However, recontouring is not a substitute for veneers or bonding. Recontouring probably would not be the best course if your teeth have a major imperfection such as a deep chip or fracture.
You should understand what recontouring can and can't do for you so you have realistic expectations. Your dentist may show you before-and-after photographs of other patients. This will allow you to see exactly what sorts of improvements are possible. Or your dentist may use a computer imaging program to show what your teeth will look like after the procedure is done.
Sometimes, recontouring can't completely fix tooth imperfections. Then your dentist may combine the treatment with bonding. In this procedure, a composite resin is used to repair or restore fractures, chips or cavities.
Recontouring doesn't affect the living pulp of the tooth. For this reason, it usually can be done without an anesthetic.
