Gum contouring is a procedure, done by a dental specialist, that reshapes or resculpts your gumline. The process of gum contouring involves cutting away or removing excess gum tissue around your teeth. If you have gum recession, the procedure involves restoring gum tissue. In many cases, gum contouring is an elective procedure. This means that it isn’t medically necessary. Instead, it’s done to improve the look of the gums, teeth, or smile. But there may be times when your dentist recommends gum contouring for oral health reasons.
