Question

8. What is tooth decay? How it is caused? List the preventive measures one should adopt to prevent tooth decay.

Answer 1

Explanation:

Tooth decay is the softening of your tooth enamel and refers to the damage of the structure of the tooth caused by acids that are created when plaque bacteria break down sugar in your mouth. If this loss of mineral from the enamel is left untreated, a cavity, or hole in the tooth, can eventually occur.

To prevent tooth decay: Brush your teeth at least twice a day with a fluoride-containing toothpaste.
