==>tooth decay starts when the pH of the mouth is lower than 5.5.

-(+)-(+)-(+)-(+)-(+)-(+)-(+)-

==> Tooth decay enamel , made up calcium phosphate is the hardest substance in the body.

-(+)-(+)-(+)-(+)-(+)-(+)-(+)-(+)

==> it does not dissolve in water, but it is corroded when the PH in the mouth is below 5.5.

-(+)-(+)-(+)-(+)-(+)-(+)-(+)-(+)-

==> bacteria present in the mouth produce acids by degradation of sugar and food particles remaining in the mouth.

==> I hope this answer is useful to you.

Answer 2

Tooth decay start when your ph of teeth get down to lower than 5.5
It can be stop by washing our mouth after eating food which has having lower ph.
