Answer 2

Answer:

if we do not clean our teeth and mouth after eating food ,then many harmful bacteria begin to grow and live on the teeth. these bacteria act on the sugar present in the left-over food particles sticking to the teeth yo form acid. the acid thus formed eats up the enamel and dentine of the tooth gradually and ultimately makes a cavity in the tooth . when this cavity reaches the pulp cavity of the tooth , our tooth becomes painful and we get toothache . if the cavities caused by tooth decay are not treated in time by a dentist, then it causes severe toothache. in extreme cases , tooth decay can lead to the loss of whole tooth
