A cavity is a hole in the tooth that is caused by tooth decay. Tooth decay is a bacterial infection that eats away at the tooth's enamel, the hard outer layer of the tooth. Cavities can be painful and can lead to tooth loss. It is important to see a dentist regularly to check for cavities and to get them treated as soon as possible.
There are a number of ways to tell if a dentist is lying about a cavity. One way is to look at the dentist's examination. A dentist who is lying about a cavity may not be able to explain where the cavity is located or may not be able to describe the symptoms of a cavity. Another way to tell if a dentist is lying about a cavity is to get a second opinion. If you are not sure whether or not you have a cavity, it is always a good idea to get a second opinion from another dentist.
