Tooth Sensitivity

This article should be read if you’re experiencing tooth pain and discomfort and aren’t sure what’s wrong. Tooth pain is not the same as dentin hypersensitivity, which is what dentists refer to as a sensitive tooth. A toothache can range from a minor cavity to a serious issue that necessitates immediate attention.

However, tooth sensitivity is very easy to detect, and there are a number of excellent solutions available that can provide you with relief and comfort right away.

If your sensitivity is caused by a tooth, the next step is to figure out whether your tooth is sensitive to hot, cold, or sweets, as each type of sensitivity can mean something different.

  • Hot?
  • Cold?
  • Sweets?
  • Intermittent Dull Ache?
  • Do you have a sharp or throbbing pain?

Main causes can include:

  • Tooth decay
  • Gum disease
  • Teeth grinding
  • Worn-down enamel
  • Damaged or cracked teeth
  • Plaque build-up

What is tooth sensitivity?

The wearing down of the protective layers of your teeth causes tooth sensitivity. The crowns, or the part of the teeth above the gumline, are protected by a layer of protective enamel, according to the American Dental Association (ADA). Cementum is a material that protects the roots below the gumline. Dentin, which is less dense than the protective coverings, lies beneath the enamel and cementum. Dentin tubules are microscopic canals found in the dentin. The dentin is exposed when the enamel or cementum wears away or becomes damaged. When your gums recede and expose the dentin, the tubules allow fluid to flow through them and are affected by heat and cold, causing sensitivity and pain in the nerves of the tooth.

What Causes Sensitive Teeth?

A layer of enamel protects the softer dentine beneath the visible portion of the tooth. A tooth can become sensitive if the dentine is exposed. The enamel layer is much thinner where the tooth and the gum meet, so this is common.

  • Too hard brushing (‘toothbrush abrasion’) and brushing from side to side can wear away enamel, especially where the teeth meet the gums.
  • The newly exposed dentine may become sensitive as a result.
  • Dental erosion is the loss of tooth enamel as a result of acid attacks from acidic foods and beverages.
  • When the enamel wears away, the dentine beneath it is exposed, which can cause sensitivity.
  • Gums may naturally recede (shrink back), exposing the teeth’s roots, which can be more sensitive.
  • The enamel layer that protects root surfaces is missing.
  • Gums may naturally recede (shrink back), exposing the roots of the teeth, making them more sensitive.
  • The enamel layer that protects root surfaces is missing.
  • Gum disease occurs when plaque or tartar builds up on the teeth, causing the gums to recede and even destroy the tooth’s bony support.
  • Pockets can form in the gums around the tooth, making it difficult to keep the area clean and exacerbating the problem.
  • Tooth grinding is a habit in which the teeth are clenched and ground together.
  • This can wear away the enamel on the teeth, causing them to become sensitive.
  • A cracked tooth, also known as a filling, is one that has become broken.
  • Tooth bleaching can cause sensitivity in some patients for a short period of time during or after the procedure.
  • Before undergoing treatment, discuss this with your dental team.

Treatments for Sensitive Teeth

It is necessary to determine the cause of tooth sensitivity in order to provide the best treatment and relieve your pain.

  • Treatments with fluoride, such as fluoride paste, gel, or rinse
  • Dietary modifications
  • To cover exposed roots, fillings are used.
  • Mouthguards for teeth grinding or resin sealants to cover exposed dentin NTI
  • Brushing habits that are better
  • Dentist-recommended desensitizing pastes
  • Root canals are a type of root canal that is used

How Long Do Dental Crowns Last?

Average lifespan of a dental crown

The average lifespan of a dental crown is five to fifteen years. The amount of “wear and tear” a crown experiences, how well you practice good oral hygiene, and your personal mouth habits all have an impact on the crown’s lifespan (you should avoid such habits as grinding or clenching your teeth, chewing ice, biting fingernails, and using your teeth to open packaging).

Decay can cause serious damage to a tooth over time. The cost of a crown, as well as its longevity, is determined by a number of factors. Accidents, in addition to decay, can cause a tooth to be broken or damaged in other ways. The average lifespans of different materials differ because some are more durable than others. If a tooth’s crown has been significantly damaged for any reason, it must be repaired.

Types of dental crowns

  • Zirconia: Zirconium dioxide, a very strong type of material related to titanium, is used to make zirconium dioxide crowns, which are classified as a type of ceramic crown.  These crowns are extremely resistant to fracture due to their durability.
  • Porcelain fused to metal: PFM (porcelain-fused-to-metal) crowns are a popular option that also happens to be one of the most natural-looking.  As a result, they’re ideal for front teeth.
  • Lithium disilicate: This glass ceramic is made of lithium (a silver-white metal) and silicon and is very strong (a hard, crystalline solid).
  • Stainless Steel:  Temporary stainless steel crowns are used to protect a tooth or filling while a permanent crown (made of a different material) is being prepared.  Stainless steel crowns are frequently used on children’s teeth to protect them from further decay and to allow the crown to fall out naturally when the permanent tooth arrives.

Temporary Crowns vs Permanent Crowns

A dentist will shave down a patient’s teeth before placing permanent crowns to ensure that the crown has a properly shaped base to adhere to.  Temporary crowns made from a mold of the patient’s natural teeth will be placed after the teeth have been shaved down.  These temporary crowns protect the patient’s newly shaved teeth from damage and allow them to function normally until their permanent crowns are placed.  Temporary crowns are made of less expensive materials such as acrylic or certain types of metal because they only need to last a few weeks.

Factors that Determine Dental Crown Longevity

  • The tooth’s location (rear, front)
  • Underneath the crown, the condition of the original tooth
  • Clenching or grinding
  • Oral hygiene and crown tooth maintenance
  • Negative habits (chewing ice, fingernails, removing bottle caps)
  • Gold, zirconia, porcelain fused to metal, and other materials were used.
  • Installation
  • The crown must be made correctly.
  • Crown (full or partial)
  • The state of your gums (gum disease)
  • External adversity (accidents)

Tips To Help Your Crown Last Longer

  • To prevent crown wear and tear, avoid biting down on hard objects or foods.
  • Regular cleanings in our office will ensure that everything is in good working order and that your crown remains healthy.
  • Do not clench or grind your teeth.
  • If you have bruxism, a mouth guard may be recommended.
  • Brush and floss your teeth on a daily basis, paying special attention to the crown area.

Do crowns last longer than veneers?

The primary distinction between a veneer and a crown is coverage.  A veneer only covers the front of your tooth, whereas a dental crown covers the entire tooth.  A crown is thicker than a veneer, so there’s a difference in thickness there as well.

How Much Do Dental Crowns Cost?

A dental crown can range in price.  The cost varies between $1,000 and $3,500, depending on the needs of each patient.  Third-party financing companies can be used to create a payment installment plan if a dental crown is not covered by an insurance policy—or if a patient does not have insurance.

How will you know when a crown needs to be replaced?

Clinical examination or dental X-rays are the only ways to determine if a crown needs to be replaced.

How long do you leave whitening gel on your teeth?

For first-time users, it is recommended to leave the whitening gel on for 30 minutes to 1 hour, and to increase the wearing time if there is little or no tooth sensitivity.

The amount of time you should leave whitening gel on your teeth for whitening will be determined by the whitening gel’s (bleach) concentration percentage. The length of time will also be determined by the color of your teeth at the start. Bleaching your teeth will take longer if they are stained or very yellow. If you don’t have any sensitivity issues, you can wear the trays for up to two hours. After you’ve finished, make sure you remove all of the excess whitening gel materials from around your gums.

For sensitive teeth, we recommend that you apply it for two weeks, once a day for 15-20 minutes, or until you achieve your desired whiteness. You should only whiten your teeth once a day. Touch-ups can be done as needed after the desired shade has been achieved.

How much Gel should I put in the trays?

Apply a thin, steady ribbon of gel to the tray’s inner surface that comes into contact with the teeth.  Important: Too much gel in the trays can cause tooth sensitivity and gum irritation.  A small amount of gel goes a long way! Keep in mind that 1 gel syringe equals about 3-4 full applications (1 full application being both the upper and lower teeth).

What strength is the gel?

The 35 percent Carbamide Peroxide Bleaching Gel syringes included in the kit are 35 percent Carbamide Peroxide Bleaching Gel.

Should I use a whitening gel?

Although over-the-counter gels and pastes are available, we recommend that you use a whitening agent provided by your dentist.  They will provide you with a professional whitening gel as well as a custom mold of your mouth to assist you in achieving your desired bright smile.  Apply the gel to the inside of the mold first, then place the mold over your teeth.  Some gels can be worn for hours at a time, while others can be worn overnight; detailed instructions will be sent home with you.  The custom mold ensures a comfortable, high-quality whitening experience that lasts longer.

Side Effects of Teeth Whitening Gels

Some people are concerned about the safety of whitening products.  Peroxide-based bleaching agents, such as those found in common tooth whitening strips and gels, can irritate the gums, according to the American Dental Association.  This can happen if the gel is applied incorrectly or with an ill-fitting tray.

How long does the teeth whitening gel last?

The shelf life of our whitening gel is two years.  The whitening gel should be kept at or below room temperature and out of direct sunlight.  The gel’s life can be extended by refrigerating it.  If the gel becomes too hot, it will turn liquid and become useless.

Is It Safe to Use the Free Teeth Whitening Gel?

Hydrogen peroxide and carbamide peroxide-based tooth whitening products, according to the American Dental Association (ADA), are both safe and effective.  Another study found that hydrogen peroxide and carbamide peroxide-based tooth whitening are both safe and effective when used according to the manufacturer’s instructions.

Are Teeth Whitening Strips Safe?

Teeth whitening strips are safe as long as the ingredient chlorine dioxide is not present.  These, and many other well-known over-the-counter products, do not contain chlorine dioxide, but be sure to read the ingredients carefully, as formulations change frequently.  Because chlorine dioxide is the same chemical that is used to clean swimming pools, it will eat away at your enamel.  Teeth whitening products containing this chemical will claim to whiten your teeth, but the chlorine dioxide will begin to eat away at your surface enamel, which is a very dangerous technique.

Whitening strips, like whitening pens, are a safe and affordable option if the instructions are followed.  Most whitening strips advise that you only use one box per year.  It is best to stop treatment if gum irritation, tooth sensitivity, or other side effects occur.  If you use the strips for longer than the manufacturer recommends, you risk damaging your enamel.  If at-home whitening methods aren’t producing the desired whitening shade, an in-office treatment can help.

What are teeth whitening strips?

Strip solutions come in a variety of brands and types, but they all have some characteristics in common.  White strips are thin, flexible, transparent or translucent strips that have a tooth whitening gel coated on one side.  The main whitening ingredient in most tooth whitening strips is carbamide or hydrogen peroxide.

Teeth whitening strips are thin plastic sheets coated with teeth whitening agents such as hydrogen peroxide or carbamide peroxide, as well as an adhesive to keep them stuck to your teeth.  They usually come in kits with enough strips to use for two weeks on both the top and bottom teeth.

How Do Teeth Whitening Strips Work?

Surface stains are removed with the help of bleaching strips.  They frequently contain peroxide bleach, which is the active ingredient.  The majority of whitening strips are made of polyethylene, a thin plastic.  These peroxide bleach-coated plastic strips are placed on your teeth to allow the active ingredient to contact the enamel.  Always read the packaging to find out how and for how long to apply the strips.

How To Select The Right Whitening Strips?

With so many different teeth whitening products on the market, you may be having trouble deciding which one is right for you.  So, rather than squandering your money by trying them all out only to discover that many of them do not perform as expected, you might want to look for the best options in a different way.

Tooth sensitivity

If your teeth are normally sensitive to cold or heat, they will most likely react to the chemicals in whitening strips as well.  Too much use of the strips can result in tooth sensitivity and long-term damage to your teeth.  The enamel layer will be eroded as a result of the frequent use of whitening agents, which will not only cause pain but also increase the risk of dental decay.

How to Manage Sensitivity

If the pain and sensitivity associated with using whitening strips is too much for you, the only way to stop it is to stop using them altogether.  If the sensitivity you’re experiencing is minor, however, there are some steps you can take to make it more bearable.  First, make sure you’re using the lowest percentage of peroxide available and that you’re using it for the shortest time possible according to the instructions.  Brushing lightly with warm water after treatment, using a specially formulated anti-sensitivity toothpaste, and avoiding hot or cold foods and drinks after using whitening strips may also help.

Can whitening strips ruin your teeth?

Teeth whitening is safe, but depending on the percentage of hydrogen peroxide used in the whitening treatment, some options may cause more sensitivity and irritation to the gums than others.  There are no long-term effects on the teeth and gums if done correctly.  Of course, you should always consult your dentist before using any at-home product, follow their instructions, and always read the manufacturer’s instructions first.  While most whitening strips are safe, using them too frequently can harm your teeth’s enamel as well as the dentin underneath.

How to Prevent Teeth Stains

Brushing and flossing your teeth before whitening may appear to be a no-brainer, but many people fail to do so! Plaque and food particles stuck between your teeth can obstruct the brightening process.

Do whitening pens damage teeth?

Tooth whitening carries some risks. Carbamide peroxide-based whitening solutions (such as those used in tooth whitening pens) are safe and effective, according to a NCBI study. A whitening pen is normally very safe to use as an over-the-counter treatment. It should, however, be used according to the directions.

You may have certain adverse effects and troubles if you take it recklessly. Overusing the pen might cause gum irritation, so be sure to follow the manufacturer’s guidelines. Chemicals and additives in some teeth whitening pens might cause tooth discomfort. Within 24 hours, these side effects are usually gone.

Is teeth whitening safe?

Yes, clinical studies have proven that whitening teeth with a dentist’s supervision is safe. Whitening is considered by many dentists to be one of the safest cosmetic dental procedures offered to the general public. Sensitivity is usually always a side effect, though it fades with time. Gum inflammation is the same way. Tooth whitening carries some danger.

How long does it last?

Teeth can be stained by eating and drinking dark foods and beverages. It’s vital to keep in mind, though, that depending on your lifestyle, the effects can diminish quickly and dramatically. Other bad lifestyle decisions can also counteract the results. The amount of time tooth whitening will last is determined by the sort of whitener you use.

When you use our whitening services, your teeth will almost always be whiter than they were before. Your personal behaviors have an impact as well.

How Well Do Teeth Whitening Pens Work?

The whitening solution does not have enough time to seep into the tooth and repair existing stains because teeth whitening pens stay on your teeth for a significantly shorter period of time than strips or professional whitening. These pens can produce some positive results if used appropriately, however they do have certain limitations when compared to professional tooth whitening.

In summary, pens can help prevent future staining, but they can’t fix discoloration that has developed over time. Dentists use teeth whitening pens to dab or brush hydrogen or carbamide peroxide onto the tooth’s surface. As a result, the best time to use a peroxide-based teeth whitening pen is just after you eat or drink something staining.

Is whitening bad for teeth?

There is no doubt that teeth whitening works, but the question is whether it is harmful to your teeth.

The short answer is that it depends. In most cases, it is considered safe, but some people may take it too far and damage their teeth as a result.

The only thing we can recommend is that you always follow the instructions when purchasing the products and that you always listen to any advice and recommendations you may receive from your dentist.

To fully comprehend the impact of teeth whitening, we must first discuss what is contained in these products:

  • Hydrogen peroxide or carbamide peroxide is found in high-quality teeth-whitening products. Higher concentrations, which are only available from your dentist, are more effective and provide longer-lasting whitening results. Peroxides can also cause tooth sensitivity, gum irritation, and chemical burns to the mouth, throat, and tongue.
  • Some less expensive products contain abrasives, which do not whiten teeth but do remove surface stains. However, using these products can lead to additional problems and should be done in moderation.

Side effects of Teeth Whitening

Teeth whitening can have a number of negative side effects. Tooth sensitivity and gum irritation are possible side effects. However, according to the Cleveland Clinic, gum irritation is usually caused by ill-fitting whitening trays (rather than the bleaching agent itself), and sensitivity and tissue irritation usually go away within one to three days of finishing the treatment.

According to one 2014 study, strong bleaching agents can cause soft tissue (gum) burns, a burning sensation in the throat, and stomach upset. The review also mentions that there is still debate about whether teeth bleaching affects the physical structure of teeth, including the enamel.

When to Avoid It

While teeth whitening has cosmetic benefits, it is not for everyone. Teeth whitening is frequently costly and does not work on all types of tooth discoloration. The American Dental Association states that whitening agents are ineffective on veneers, fillings, crowns, and caps and are unlikely to work for discoloration that is brown, gray, or caused by injury or medication. That is why it is critical to consult with your dentist before investing in teeth whitening products.

How Often Should I Whiten?

Too much whitening raises the risk of negative side effects like tooth sensitivity and damage to tooth enamel and gums. However, there is no formal recommendation for how often teeth can be whitened safely. That’s why it’s critical to seek your dentist’s advice and adhere to all product directions. After one month, some people notice that the whiteness has faded, while others can last a year without needing another whitening procedure.

What about the enamel?

Enamel on teeth is the toughest tissue in the body, even tougher than bone! The enamel’s duty is to protect the dentin, which is the softer and more sensitive inner tooth. The most prevalent indicator of damaged enamel is yellow discolouration of the teeth. This raises the question of whether teeth whitening harms the enamel. Teeth whitening does not harm your tooth enamel, so the answer is no.

Signs Of Enamel Erosion

  • Pain is caused by sensitivity to specific foods and temperatures.
  • Discoloration in the color yellow.
  • Teeth may become rougher, uneven, or jagged as they age.
  • On the surface of your teeth, indentions may occur.


Always read the directions and do precisely what your dentist recommends when it comes to teeth whitening. Teeth Whitening is not harmful to your teeth as long as you follow these guidelines.


How much does teeth whitening cost?

There are several teeth whitening options, and the cost varies greatly depending on which one you choose. In-office services, such as Phillips Zoom!, typically start around $500 and increase in price depending on the number of treatments required and the severity of your teeth stains. This option is quick and effective, but it can be extremely expensive to maintain because continued results often necessitate a number of visits per year.

Dentists’ take-home options are less expensive and just as effective. These customized application trays mold to your teeth, ensuring consistent whitening while reducing the risk of tooth sensitivity and tissue irritation. Typically, the cost of a set ranges between $200 and $600. This one-time fee provides you with trays that can be used as often as necessary with professional-strength whitening gel provided by our office.

Over-the-Counter Products

Kits sold in stores range in price from $30 to $200 and include application trays and bleaching gel. Whitening strips can be as cheap as $10, but they are more commonly in the $20 range. The least expensive option, whitening toothpaste, can range from $5 to $15 or more, depending on the formulation.

These low prices for teeth whitening may appear appealing, but they are frequently a waste of time and money, and may even result in increased teeth sensitivity, soft tissue irritation, and inconsistent results.

The Benefits of Professional Teeth Whitening Kits

Our personalized tray-whitening kits provide the following two major advantages:

  • Customized application trays help ensure consistent whitening of all of your teeth while reducing the risk of solution seepage. The gums, tongue, and cheeks are protected from irritation by keeping the whitening solution in place.
  • The professional strength whitening solution we provide is not available over the counter. Our solution’s active ingredient is free elemental oxygen, which oxidizes stains to remove them permanently, safely, and comfortably – and because you keep the customized application trays, results can be maintained as you see fit, in the privacy of your own home, on your preferred schedule.

It is important to remember that while any toothpaste can claim to be “whitening,” even the most expensive can only remove stains from the surface of the teeth. Whitening strips cover the front teeth, but a full smile will reveal highly visible color differences, and over-the-counter tray whiteners – even those with “boil and bite” applicators – frequently produce inconsistencies while increasing teeth sensitivity and tissue irritation. Professional teeth whitening from a reputable cosmetic dentist is the safest, quickest, and most dependable method of brightening your smile.

Best Teeth Whitening LED Accelerator Lights

Are There Any Side Effects Related to Blue LED Light Tooth Whitening Kits?

At-home teeth whitening kits are generally safe to use as long as you follow the directions and don’t overuse them. They’ve been specifically designed to be safe for untrained users to use at home. However, you must ensure that your teeth are healthy enough to undergo whitening treatment, as the amount of whitening agent contained in some whitening kits may cause tooth damage if your enamel is not strong enough.

Can I eat or drink after using Smile Direct Teeth Whitening products?

After using the Smile Direct Club whitening treatment, we recommend waiting at least 20 minutes before eating or drinking.

Can I use an LED Light with the whitening strips?

Yes! You can use our LED Accelerator Lights at the same time as the whitening strips. To begin, place the whitening strips on your teeth. After that, turn on the LED Light and place it in your mouth while biting down on the mouthpiece. The entire whitening strip treatment can be done with the LED Light. After you’ve finished, turn off the LED light, rinse the mouthpiece, and set it aside to dry.

Do Blue Lights Whiten Teeth?

Blue lights, like ultraviolet light, do not whiten teeth when used alone. However, it is thought to improve and speed up the results by enhancing the reaction of the bleaching agent on the teeth.

Does Blue Light LED Teeth Whitening Really Work?

To summarize, at-home teeth whitening kits do produce varying levels of results and make your teeth appear whiter than they were previously. Even if you have badly stained teeth, at-home whitening kits can give you dramatic results, but the extent of your results will depend on the kit, treatment time, adherence to the treatment regimen, and whether or not you practice good oral hygiene habits both during and after the tooth whitening treatment. Learn more about how LED light can help you whiten your teeth.

Does LED actually make teeth brighter?

I drank the same amount of coffee, red wine, and tea while using the whitening kit. I’d say it works because I didn’t do anything else differently — I use a whitening toothpaste every day, but this seems to have made a bigger difference.


On this one, the jury is still out. Many studies on the effectiveness of using lights on bleaching gel to improve the speed of the magnitude of the results are currently being conducted. Some studies, such as this one from 2011, show that activating an LED light causes a significant color change. According to this study, light activation causes a faster and more intense bleaching effect. Multiple studies, on the other hand, claim that the use of lights, whether lasers, halogen lamps, or LEDs, has no increased whitening effect. “When compared to chemical bleaching, the use of light activation did not show any advantages. The length of time the gel stays in contact with the teeth, according to the researchers, is the most important aspect of the whitening process. When using an LED light, this study found a higher level of tooth sensitivity.

Does UV Light Really Whiten Teeth?

No, UV light alone does not whiten teeth. It does, however, accelerate the reaction of bleaching agents, resulting in faster and potentially whiter results.


Hydrogen peroxide or a close derivative known as carbamide peroxide is usually the main ingredient in teeth whitening gel. Hydrogen and oxygen make up these molecules. The hydrogen and oxygen in the molecule break apart as it interacts with your teeth, causing a deep cleaning action. When the molecules are exposed to your teeth, higher temperatures, or ultraviolet light, they become active (UV). This is why ordinary hydrogen peroxide (for cleaning wounds) is sold in a brown bottle (to prevent sunlight from penetrating the bottle) with instructions to keep it cool.

How do teeth whitening kits work?

I brushed my teeth, applied the gel, then the amplifier, and then watched TV while holding the LED light to my teeth for 10 minutes. The light was turned off after ten minutes, and I rinsed.

How Does An LED Light Teeth Whitener Work?

The LED light teeth whitening system is a non-invasive, bleach-based treatment. The kit consists of a whitening agent, an applicator or a syringe, mouth trays, and an LED light.

How Does LED Teeth Whitening Work?

Did you know that you could have your smile brightened about 5-10 shades in as little as 20 minutes? Not only that, but professional teeth whitening procedures are also needle-free and don’t require the use of a dental drill. Instead, the process is as simple as placing the whitening agent, applying an LED light, and letting it sit.

How Does The LED Light Device Work?

LED teeth whitening kits work by combining the bleaching ability of peroxide whitening agents which break down the chemical structure of stains with intense blue LED light which speeds up the chemical reactions.


Teeth whitening kits that use accelerator lights can be a cheap but effective way to brighten your teeth. A kit that includes a powerful 35% peroxide bleaching gel will cost between $20 to $50 which is significantly cheaper than professional treatments.

Is it worth it?

At a significantly higher price point, you may want to stick to regular whitening strips. But the process is kind of fun, and made me more inclined to keep my dental routine in line. I found myself brushing and flossing a lot more regularly as part of the regimen.

Is Led Teeth Whitening Safe?

LEDs release visible light, rather than ultraviolet light, which is known to harm cells and tissues. LED teeth whitening is therefore much safer than UV teeth whitening. However, care should be taken when applying the bleaching agent to teeth as it can cause discomfort and sensitivity to the gums.

Is LED Whitening Safe For Your Teeth?

Smile Direct Club Teeth Whitening Reviews: Does it Really Work?

Are you tired of having yellow, stained teeth? Do you wish you had a bright, white smile that dazzles every time you flash it? Smile Direct Club offers you a whitening solution that works.


The only laser teeth whitening light that actually works are the UV producing lights that are offered at your local dentist.


Ultraviolet (UV) light is a frequency of light that is proven to accelerate the whitening process. UV is a frequency of light most often associated with light from the sun, tanning bed lights, greenhouse lights, and in-office dentist “laser” teeth whitening. All of these create the UV frequency known to speed up the activation of hydrogen and carbamide peroxide.

So, how do LED lights help?

At this point, you are probably wondering how an LED light can help this process along. An LED, or light-emitting diode, releases a single color of light on the visible light spectrum when exposed to electricity. In the past UV, or ultraviolet light, was used to aid in the whitening process. However, UV light has been found to cause cell mutations that can lead to cancer.

Top 8 Teeth Whitening Myths Debunked ??

?? Welcome, it’s great to have you here. We sell aligners online and are happy to share our knowledge on the subject.

What are the basics of teeth whitening?

When you visit your local dental office to have your teeth professionally whitened, your teeth will first be cleaned to ensure that the whitener can be evenly applied to the surface of your teeth. You will also be given special tools used to hold your mouth open and protect the soft tissues of your mouth during the whitening procedure. Once applied to your teeth, the whitening gel will remain in place for about 20 minutes.

What Are The Benefits Of Using LED Tooth Whitening Systems At Home?

The first benefit is obvious: whitening your teeth in the privacy of your own home is convenient and discreet. It is also much more affordable than going to the dentist’s office every few months to have your teeth professionally whitened.


In general, based on the current research, we do not know if lights make a difference in the speed or effectiveness of whitening. We do know that adding heat to any peroxide whitening gel makes it work faster. This means that a heat-generating light will speed up the whitening process. Because LEDs do not produce much heat, if they work at all, it is not through this mechanism. Any high strength peroxide gel will produce whitening results with or without light activation. It is more important to keep the gel in contact with the teeth for the recommended period of time than to add the light.

What Does Smile Direct Club Teeth Whitening Cost?

Smile Direct whitening pens and the Smile Direct Club led accelerator light sell in a kit or individually. You get a teeth-whitening kit featuring a 12-month supply of teeth whitening formula, and an accelerator LED light for $67. A six-month supply with an LED light costs $40.

What Is Included In A Blue LED Light Teeth Whitening Kit?

While some of the components might vary from kit to kit, the main pieces are usually going to be the same. Most LED teeth whitening kits come with a whitening gel that you either place in a tray, or like in the case of some teeth whitening products that we looked at, the tooth whitening gel has been applied to strips that you can easily place on your teeth.

What Is The Best Led Teeth Whitening Kit?

What Is The Best Teeth Whitening Product On The Market?

The best teeth whitening product on the market is the AuraGlow At-Home Teeth Whitening kit. It is very easy to use and gives you fantastic, professional-looking results.

When is the best time to use Smile Direct Club teeth whitening products?

The best time to use Smile Direct Club whitening products is before you go to bed. Finish brushing your teeth and then go through your whitening protocol.


Most likely, yes. The kits we have seen use a high strength carbamide peroxide or hydrogen peroxide whitening gel, and they instruct the user to “wear” the gel under the light for about thirty minutes each day for maximum results. Applying that high strength gel to the teeth will cause a visible whitening result. Carbamide peroxide gels can penetrate tooth enamel to break down darkly colored pigments inside the tooth, thus lightening the overall color of the teeth. This will happen regardless of whether or not you also use a light on the teeth.

Will it save time?
