Sweets and tooth decay

SWEETS AND TOOTH DECAY

Normally bacteria are present in our mouth but they are not harmful to us.
However, if we do not clean our teeth and mouth after eating, many harmful bacteria also reside and grow in it.
These bacteria break down the sugars present from the leftover food and release acids.

The acids gradually damage the teeth. This is called tooth decay.

Cavities

CAVITIES

Our mouth is inhabited by a number of micro organisms.
Bacteria - tiny colonies of living organisms are constantly on the move on our teeth, gums, lips and tongue.
Having bacteria in our mouth is a normal thing.
While some of the bacteria can be harmful, most are not and some are even helpful.

Digestion

DIGESTION

The process of digestion starts in the mouth itself where the food is mixed with saliva.
