It is made of harmful microscopic bugs that use sugar to attack teeth. With time this creates a little hole in a tooth, and if not repaired with a filling, the cavity continues to grow. If a cavity is not treated it can destroy a good part of the tooth, making it hard to be rapaired with a conventional filling.
A cavity is the result of bacteria in the mouth, and its reaction to sugars and starches. As bacteria break down the sugars and starches, sticky plaque filled with acids form over the tooth. If left unchecked, plaque can form tartar, which cannot easily be brushed away.
