Will brushing teeth with baking soda make teeth whiter?

Brushing teeth with baking soda may, to some extent, make teeth appear whiter, but the effect is limited and should be used cautiously. Baking soda has mild abrasive properties that can help remove surface stains on teeth, such as those caused by coffee, tea, or smoking, thereby making teeth appear slightly brighter. Additionally, baking soda's alkaline properties can neutralize the acidic environment in the mouth, reducing bacterial growth and promoting oral health. However, long-term or excessive use may lead to tooth enamel wear, increasing tooth sensitivity and the risk of damage.

If choosing to brush with baking soda, it is recommended to limit the frequency to no more than once or twice per week, and avoid applying pure baking soda powder directly onto the teeth. It can be mixed with a small amount of water to form a paste and used with a soft-bristled toothbrush to gently clean the tooth surface. Regular brushing should still be done with fluoride toothpaste to ensure adequate dental protection. For persistent tooth discoloration, professional teeth whitening methods, such as in-office light-activated whitening or dental cleaning, may be safer and more effective. If you have any concerns or experience tooth sensitivity, consulting a dentist is a more reliable option.
