Answer 2

Hey mate..

Here's your answer..

=========================================================

Tooth enamel is the outermost covering of teeth...It is made
up of ✳CALCIUM CARBONATE✳..

The sugars and the acids present in the food we eat remain
in our buccal cavity ...the acids released spoil our teeth.

When the pH of our mouth falls below 5.5 tooth decaying may
begin...

❇There are some bacteria, however, that we'd rather do without,
since they cause tooth decay and gum disease. Streptococcus
mutans is the bacteria you've probably heard the most about.
It lives in yourmouth and feeds on the sugars and starches that
you eat.❇


⭕PREVENTION:

We use toothpaste which are alkaline in nature and neutralise
the acids.
