Can Orthognathic Surgery Fix a Gummy Smile?
If you feel you show too much gum when you smile, here is how jaw surgery can help.
Yes β orthognathic surgery can effectively correct a gummy smile (excessive gingival display) when it is caused by the position of the upper jaw. This is done through a procedure called a maxillary impaction or maxillary osteotomy.
- When jaw surgery is appropriate for a gummy smile:
- The upper jaw (maxilla) is too long vertically
- Showing 4+ mm of gum above the teeth when smiling
- The problem is skeletal, not just related to the teeth or gums themselves
- You also have other functional issues (open bite, difficulty closing lips)
- How it is done:
- The upper jaw is moved upward (impacted) through a maxillary osteotomy
- This raises the gum line and reduces gum show
- The procedure is done through incisions inside the mouth
- The lower jaw may need to be repositioned as well to maintain a proper bite
- Alternatives for a gummy smile:
- Botox β temporarily relaxes the upper lip. Lasts 3β4 months
- Gum contouring β removes excess gum tissue. Works if the gum itself is the issue
- Lip repositioning β surgical shortening of the lip
- Crown lengthening β removes gum and bone around teeth
When to Consider Surgery
If your gummy smile is caused by a long upper jaw (not just excess gum tissue or a hyperactive lip), and you also have other functional issues like an open bite or lip strain, orthognathic surgery can provide a permanent solution.
Clinical Guidance
A gummy smile caused by a vertically long upper jaw can be corrected with orthognathic surgery (maxillary impaction). This shortens the upper jaw and reduces gum show permanently. Less invasive options exist for non-skeletal causes of a gummy smile.
