Strawberries and Baking Soda for Whiter Teeth: Debunked – Roya Arbab, D.D.S
You may have heard the recent claim that a mixture of fruit and baking soda applied to the teeth will whiten them dramatically, inexpensively and in a much more “organic” way than traditional bleaching methods.
In particular, young adults and teens have shown themselves to be susceptible to this advice. They readily experiment with it and spread the idea throughout their community because the materials involved are so easily accessible.
While the claim has some merit and certainly comes from well-meaning sources, we feel that we should set the record straight. New research done on the subject from Professor So Ran Kwon of the University of Iowa shows that while the mixture does brighten the smile a bit, it does so merely by removing superficial debris. So although the teeth may look whiter, the effect is short-lived. As plaque and debris build up again, the teeth will darken.
In addition to that, the fruit and baking soda mixture method may reduce the surface hardness of your teeth, leaving them vulnerable to decay.
To achieve a permanently whiter smile, what you really need is a substance that penetrates into teeth and breaks down stain molecules, whitening teeth from the inside out for better and longer-lasting results.
If you want whiter teeth, we urge you to use ADA approved methods for achieving that brighter smile!
