From subtle changes to major repairs, your dentist can perform a variety of procedures to improve your smile. There are many techniques and options to treat teeth that are discolored, chipped, misshapen or missing. Your dentist can reshape your teeth, close spaces, restore worn or short teeth or alter the length of your teeth. Common procedures include bleaching, bonding, crowns, veneers and reshaping and contouring. These improvements are not always just cosmetic. Many of these treatments can improve oral problems, such as your bite.
