Question

How plaque is formed?What is tooth decay?​

Answer 1

Answer:

Plaque forms when bacteria in your mouth mix with sugary or starchy foods, such as milk, juice, soft drinks, bread, pasta and fruit. These bacteria release acids that break down carbohydrates in food and drinks.

Tooth decay is damage to a tooth's surface, or enamel. It happens when bacteria in your mouth make acids that attack the enamel. Tooth decay can lead to cavities (dental caries), which are holes in your teeth.

Cavities are permanently damaged areas in the hard surface of your teeth that develop into tiny openings or holes. Cavities, also called tooth decay or caries, are caused by a combination of factors, including bacteria in your mouth, frequent snacking, sipping sugary drinks and not cleaning your teeth well.
