Small chipped enamel with no pain

If small enough, the rough area can be smoothed over with a polishing drill and left as is. The dentist will need to know why the tooth chipped to prevent it happening again. Some common reasons are trauma (knocked it), bit hard on something, weakened enamel from acid erosion (such as acid reflux, frequent softdrink or lemon consumption), weakened teeth from previous dental fillings, or dental decay.
