It is possible to correct the condition of exposed gums when smiling, depending on the specific situation in the mouth. If the gums are showing when you smile because the alveolar bone and teeth are protruding outward, the problem can be solved by correcting the teeth. If the protrusion of the alveolar bone is more pronounced and severe, orthognathic surgery can be performed to correct the problem. In another case, the gums may be exposed when smiling because the lip is too short, in which case lip lengthening is required. If it is caused by high alveolar bone, in this case you need to go for surgery to correct the problem, and you need to go to a regular dental institution for symptomatic treatment.
