cavity

A cavity is a hole in a tooth that is caused by decay. Decay is caused by bacteria that live in your mouth. These bacteria produce acids that break down the enamel, the hard outer layer of your teeth. If the decay is not treated, it can eventually reach the inner layers of your teeth, causing pain and infection.

Cavities are very common, especially in children. They can be caused by a number of things, including not brushing your teeth regularly, eating sugary foods and drinks, and having dry mouth.

There are a few things that you can do to prevent cavities, such as:

• Brushing your teeth twice a day for two minutes each time
• Flossing your teeth once a day
• Eating a balanced diet that is low in sugar
• Drinking water instead of sugary drinks
• Visiting your dentist for regular checkups and cleanings

If you have a cavity, it is important to see your dentist as soon as possible. The dentist will be able to fill the cavity, which will prevent the decay from spreading.
