Final answer:
Baking soda can be used to whiten teeth, but caution should be taken to avoid tooth enamel erosion. It is best to consult with a dentist for professional advice.
Step-by-step explanation:
Teeth whitening is a popular procedure to remove discoloration. While professional whitening treatments and toothpastes containing peroxides are most effective, baking soda can also help whiten teeth to a certain extent. The abrasive nature of baking soda helps remove surface stains from teeth, but it may not be as effective as other whitening methods and should be used with caution.
Using baking soda to whiten teeth involves making a paste by mixing baking soda with water. The paste can then be applied to the teeth and gently brushed for a couple of minutes. However, it's important to note that excessive use of baking soda can erode tooth enamel and lead to tooth sensitivity.
Therefore, it's recommended to use baking soda as a whitening agent sparingly and consult with a dentist for professional advice.
