Gum recontouring is one of the easiest ways to give someone a bigger, broader smile without doing anything to the teeth themselves. You may have naturally large beautiful teeth that look small or smaller, simply because there is too much gum covering your own natural tooth. Gum recontouring is done with a laser and simply removes the excess gum tissue from the tooth, leaving you with a bigger broader smile instead of a “gummy smile.” Sometimes a small amount of extra gum can make a tooth look short square instead of its natural shape and size.
