Contouring, also known as tooth reshaping, is the simplest treatment now available in cosmetic dentistry. Dental reshaping and contouring is a procedure to correct small irregularities of teeth in just one session. The dental contouring procedure can make substantial changes in the appearance of the smile even though it is a procedure of subtle modifications. It can alter the length, shape or perceived position of teeth, and frequently be used instead of more involved and costly options. Smoothing chips and irregularities on the biting edges of anterior teeth can make them not only more attractive, but less likely to continue to chip.
