Are you looking for the best teeth-whitening method? Visit this in-depth post to discover these incredible techniques.

Effectiveness and Results of Baking Soda in Teeth Whitening

This very common ingredient has a slightly abrasive texture, which in theory makes it a candidate for removing those superficial stains caused by smoking or the consumption of certain foods and drinks, including:

● Coffee

● Tea

● Red wine

● Soda

● Soy sauce

● Energetic drinks

Many people swear that after using baking soda, their teeth acquire a shine and whiteness they did not have before. But here’s the fine print: baking soda is not a magic wand that can change the intrinsic color of your teeth, nor is it effective on deep stains.

The results you can get from using baking soda to whiten your teeth will vary greatly, depending on how marked the stains are, the tooth structure, and how often the substance is used.

In addition, it is important to mention that this study was carried out on extracted teeth, repeating the application of sodium bicarbonate 2 times a day. This frequency, however, is not recommended by dentists because it could generate sensitivity and porosity of the teeth.
