The best result with laser gum contouring is achieved in people whose teeth are covered with overgrown gum. There may also be cases where there is no overgrown gum, but a patient might just want to show less gum. Laser gum contouring can be effective in such cases as well, but it would depend on the depths of the periodontal pockets they have (ie the space around the teeth and tip of the gum). Usually the gum can be reduced between 0.5 mm and 2 mm. Also the bio-type of the gum determines how much of the gum can be reduced.

For people who want to improve their gummy smile, laser gum contouring can make a difference, but one has to be aware that it can have limited results. In dental terms, reduction of 1-2 mm of gum can make a large difference.
