Question

Mention the nature of toothpastes. How do they prevent tooth decay?​

Answer 1

$\pink{\bold{\underline{\underline{Nature\:of\:toothpaste:-}}}}$

Toothpaste is alkaline in nature. The action of bacteria occurs in acidic medium in the mouth and hence toothpaste neutralises the acid and doesn't allow tooth decay to occur.

$\blue{\bold{\underline{\underline{To\:prevent\:tooth\:decay:-}}}}$

Brush twice a day with a fluoride toothpaste. Clean between your teeth daily with floss or interdental cleaner. Eat nutritious and balanced meals and limit snacking.

Answer 2

Answer:

$\huge{\underline{\mathtt{\red{❥A}\pink{N}\green{S}\blue{W}\purple{E}\orange{R}}}}$The pH in our mouth is 5.5 which is slightly acidic. If the pH in our mouth decreases it results in tooth decay due to formation of certain acids. Toothpaste is basic in nature which neutralizes the acid and protects from tooth decay.
