A filling is a material that your dentist uses to fill a cavity after he or she removes any tooth decay. To fill a tooth, your dentist will: 1  Numb your teeth, gums, tongue, and surrounding skin. 2  Sometimes use a small sheet of rubber on a metal frame (rubber dam) to target the decayed tooth and to stop liquid and tooth chips from entering your mouth and throat. 3  Drill out all the decay and replace it with a filling.
