Baking Soda Teeth Whitening

Baking Soda (or Sodium bicarbonate) is a weak alkaline powder.  When it comes in contact with water, it releases free radicals that attack teeth stains and help to remove discoloration.  It is mildly abrasive, and gentle scrubbing will also help to remove stains caused by some beverages as well as plaque (which have a yellowish color).  Baking soda teeth whitening is also inexpensive.  Personally I do not recommend baking soda as a teeth whitener; as it could harm your teeth.  However, I will still provide the information as a lot of patients ask me about baking soda teeth whitening.

Options for using Baking Soda for Teeth whitening

Baking Soda with Lemon or Strawberry

Baking Soda with Lemon or Strawberry

  1. Baking Soda with Water. You can mix the baking soda with water or simply wet your toothbrush and dip it into the baking soda powder.  Brush your teeth thoroughly and rinse your mouth afterwards.
  2. Baking Soda and Strawberry. Strawberries have anti-oxidant properties and whiten teeth pretty well, even if used without baking soda. If you prefer, you can mash it up and mix it with baking soda to make a paste to brush your teeth.  Rinse very well after brushing.
  3. Baking Soda and Lemon Juice. Lemon also has bleaching abilities.  You can mix it with baking soda to make a paste and apply to your teeth.  Leave it for 2 minutes and rinse thoroughly.  Don’t use this more than once a week as lemon juice is very acidic and could erode your teeth.
  4. Baking Soda and Salt. The salt makes the powder more abrasive and may therefore be more effective in removing tough stains.  Use about 5 ml of table salt to 15 ml (three teaspoons) of baking soda.
  5. Baking Soda and Toothpaste. The baking soda can be added to your toothpaste.  Brush for the normal 2 minutes.

Risks in Using Baking Soda for Teeth Whitening

  • As baking soda is very abrasive and regular use can cause excessive wear to your teeth (called abrasion). Do not scrub vigorously or use it more than two or three times a week.  You can literally brush away the enamel, especially close to the gumline where the enamel is quite thin.  This will weaken your teeth and is likely to result in tooth sensitivity.
  • When using strawberries, lemon juice or vinegar you must remember that they are very acidic and will cause erosion of your teeth if use too often. This will result in weaker enamel, a higher caries risk and also tooth sensitivity.
  • Baking soda doesn’t kill the bacteria that cause tooth decay. It also does not contain fluoride which is very important in strengthening your teeth and prevent cavities.
  • If you wear braces or use a permanent retainer, don’t use baking soda as it will soften the glue.

As mentioned before, Baking Soda Teeth Whitening is probably not a very good option as a lot a of other whitening products will be more efficient and less harmful to your teeth.
