A) Describe how tooth decay takes place?
b) How to prevent tooth decay?

Explanation:

a) Tooth decay occurs when foods containing carbohydrates (sugars and starches), such as breads, cereals, milk, soda, fruits, cakes, or candy are left on the teeth. Bacteria that live in the mouth digest these foods, turning them into acids. Which damages the enamel and then damages the dentine towards the nerve ends.

b.)

1. Brush your teeth at least twice a day with a fluoride-containing toothpaste.

2. Clean between your teeth daily with dental floss or interdental cleaners.

3. Rinse daily with a fluoride-containing mouthwash.

4. Eat nutritious and balanced meals and limit snacks. Avoid carbohydrates such as candy, pretzels and chips, which can remain on the tooth surface.

5. After sticky foods are eaten, brush your teeth soon afterwards

6. Check with your dentist about use of supplemental fluoride, which strengthens your teeth.
