Vedclass · Answer

(C) Tooth decay starts when the $pH$ of the mouth falls below $5.5$.This happens because bacteria present in the mouth produce acids by degrading sugar and food particles remaining in the mouth after eating.These acids corrode the tooth enamel,which is made of calcium hydroxyapatite (a crystalline form of calcium phosphate),the hardest substance in the body.

At which value of $pH$ of the inner side of the mouth does the decay of teeth take place?
