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 harmfulbacteria also begin to live and grow in it. These bacteria break down the sugars

present from the leftover food and release acids (see Chapter 5 to know what an

acid is). The acids gradually damage the teeth (Fig. 2.5). This is called tooth decay.

If it is not treated in time, it causes severe toothache and in extreme cases results

in tooth loss. Chocolates, sweets, soft drinks and other sugar products are the

major culprits of tooth decay. Therefore, one should clean the teeth with a brush

or datun and dental floss (a special strong thread which is moved between two

teeth to take out trapped food particles) at least twice a day and rinse the mouth

after every meal. Also, one should not put dirty fingers or any unwashed object in

the mouth.
