Question

How does tooth enamel get damaged? What should be done to prevent it?

Answer 1

Substances like chocolates and sweets are degraded by bacteria present in our mouths. When the pH falls to 5.5, tooth decay starts. Tooth enamel is the hardest substance in our body, and it gets corroded. The saliva produced by salivary glands is slightly alkaline; it helps to increase the pH to some extent, but tooth paste, which contains basic substances, is used to neutralize excess acid in the mouth.
