Using baking soda for teeth whitening or cleaning can cause several side effects, especially if used too often or too aggressively[2]. Its abrasive texture can wear down the protective enamel on your teeth, which may lead to increased sensitivity to hot, cold, or sweet foods and drinks[2][4][7]. Once enamel is damaged, it does not regenerate, making teeth more vulnerable to cavities and decay[4][7].
Frequent or improper use of baking soda may also irritate the gums, leading to discomfort, inflammation, or even sores in your mouth—particularly in sensitive individuals who may develop allergic reactions such as rashes or burning sensations[1][4]. Aggressive brushing with baking soda can also cause gums to bleed or recede[4].
Baking soda does not contain fluoride, which is necessary for strengthening enamel and protecting against cavities. As a result, relying on baking soda alone for oral care may increase your risk of tooth decay, especially if you do not use fluoride toothpaste in addition[4][7]. Additionally, baking soda’s whitening effect is limited to removing surface stains; it does not address deeper, intrinsic discoloration and is not as effective as professional whitening treatments[5].
Other potential disadvantages include unpleasant taste and gritty texture, the possibility of softening adhesives in dental fixtures (such as braces), and the lack of standardized guidelines for safe use[5][7]. Individuals with pre-existing oral health problems should consult a dentist before using baking soda for dental hygiene[7].
