An attractive smile exposes minimal gum tissues. In a gummy smile more amount of gum is visible which makes the smile less attractive. This problem can be treated in many ways. A periodontist chooses a particular process based on the complexity of the condition. Laser treatment is one of the commonly performed procedures. However, in more complex cases a surgical contouring or lip repositioning may be necessary. The treatment for gummy smile can also be called crown lengthening. A periodontist or a dentist who has specialized experience in curing gum problems can treat a gummy smile.
