Question

C. If we do not clean our teeth and mouth after eating food, then many harmful microorganisms called A begin to grow and live on the tooth. These microorganisms act on the substance B present in the left-over food particles sticking to the tooth to form C which affect the teeth. This causes tooth decay and leads to the formation of a hole called D.

Answer 1

Answer:

Is this a question I can't understand

Answer 2

Answer:

A=PLAQUE

B=SUGAR

C=ACID

D=PULP

E=ENAMEL

F=ROOT

Explanation:If we do not clean our teeth and

mouth after eating food, then many

harmful microorganisms called PLAQUE

begin to grow and live on the tooth.

These micro organisms act on the

substance SUGAR present in the leftover

food particles sticking to the tooth to

form ACID. The ACID eats up the part PULP and

ENAMEL of the tooth gradually and

ultimately makes a hole in the tooth.

When this hole reaches part ROOTS of the

tooth it becomes painful and we get

toothache.
