Question

how dental decay is caused​

Answer 1

Answer:

Cavities are permanently damaged areas in the hard surface of your teeth that develop into tiny openings or holes.

Answer 2

Explanation:

When decay-causing bacteria come into contact with sugars and starches from foods and drinks, they form an acid. This acid can attack the tooth’s enamel causing it to lose minerals.

This can happen if you eat or drink often, especially foods and drinks containing sugar and starches.
