Why do dentists fill holes in your teeth?
Cavities, also called tooth decay or dental caries, are caused by bacteria. If brushing and flossing don’t clean the bacteria off the teeth, it has a chance to eat away at the tooth’s enamel. The result is a hole: a cavity. Dentists numb the area and use a drill to remove the decayed part of the tooth. They then fill the hole.
