The diagnosis of a "gummy smile" varies from patient to patient and is mostly determined by how the patient feels about his or her grin. As the downsides of a gummy smile are often cosmetic, it's widely termed as a perception problem. A gummy smile can make a person self-conscious, which might lower his/her self-esteem.
What Is the Cause?
Malaligned Teeth
Teeth erupted improperly and partially covered by gum tissue
Genetics
Short or hyperactive upper lip
Gingival hypertrophy
Vertical maxillary excess, that makes gums bulge out
How Are Gummy Smiles Treated?
A few common treatments are as follows:
Laser Treatment: When the gum tissue is the issue, laser treatment is a popular alternative for patients.
Braces/Aligners: Braces can minimize the look of a gummy smile by realigning a person's teeth.
Gum Recontouring: To improve the look of a gummy smile, the gums and the bones to which they are attached can be "sculpted."
