A cavity is a hole in the tooth that is caused by bacteria. If left untreated, a cavity can cause pain, infection, and tooth loss. There are a number of things you can do to get rid of a cavity before it becomes a serious problem.
One of the most important things you can do is to brush and floss your teeth regularly. This will help to remove plaque and bacteria from your teeth and prevent cavities from forming. You should also avoid sugary foods and drinks, as these can contribute to the formation of cavities. If you have a cavity, you should see a dentist as soon as possible to have it treated.
