Question

which constituent is use to prevent tooth decay

Answer 1

Solution :-

The correct answer of this question is fluoride.

Fluoride is a mineral that occurs naturally in many foods and water. Fluoride helps prevent tooth decay by making the tooth more resistant to acid attacks from plaque bacteria and sugars in the mouth. It also reverses early decay. In children under 6 years of age, fluoride becomes incorporated into the development of permanent teeth, making it difficult for acids to demineralize the teeth. Fluoride also helps speedy remineralizeation as well as disrupts acid production in already erupted teeth of both adult and children.

Answer 2

Calcium is the most important constituent for preventing tooth decay, especially for growing children.

Dairy products such as milk, yogurt, curd and cheese play an important role in it.

Other options are leafy greens such as broccoli and bok choy, canned fish with bones, almonds, Brazil nuts and dried beans.
