Question

Tooth enamel is one of the hardest substances in our boady how does it undergo damage due to eating chocolatees and sweets hoe do tooth pastes prevent this damage

Answer 1

When we eat sweet things the the bacteria present in our mouth starts releasing acid which decreases the pH value of our mouth 5.5.

so due to decrease in pH value our tooth enamel starts corroded..

so to overcome this problem we are advised to use toothpaste which is basic in nature and neutralises the effect of acid..

Answer 2

Answer:

Sugar present in chocolates and sweets gets broken to acids by bacteria present in the mouth. This lowers the pH in the mouth. Tooth enamel is made up of calcium phosphate, which gets corroded when the pH in the mouth is below 5.5. To prevent tooth enamel from decay, toothpaste is used because it is alkaline and neutralises the acid produced in the mouth and helps to prevent lowering of pH in mouth.
