Does more gum show than you’d like when you smile? It’s one of the more common cosmetic questions patients bring up, and the cause is usually straightforward to pin down. Here’s what’s behind it, and the full range of ways it can be corrected.
What Is a Gummy Smile?
“Gummy smile” is just the everyday name for excessive gingival display. A normal smile shows about 1 to 2 millimeters of gum above the upper teeth; many clinicians consider anything beyond 3 to 4 millimeters excessive, though definitions vary.
It’s not a health issue by itself. For most people, it comes down to one or more structural things: how the teeth came in, how the jaw grew, or how the upper lip moves.
What Causes a Gummy Smile?
There are a few different reasons this happens, and it’s often more than one at once. Figuring out which applies to you is the first step before anything gets treated.
- The gum tissue didn’t fully recede — gum tissue normally migrates down the tooth as it matures, and sometimes it doesn’t fully get there, leaving more gum covering the upper teeth than usual
- The teeth erupted further than average — when the upper teeth come in a bit too far, the gumline comes down with them, so more gum shows when the lip lifts
- The upper jaw grew slightly long — a skeletal cause where the upper jaw is a touch longer top to bottom than average, often alongside lips that don’t quite close at rest
- The upper lip simply lifts higher — for some people, it’s not about teeth or jaw at all; the lip muscle just raises more when they smile
A short upper lip, or a labial frenulum (the little tissue band connecting lip to gum) sitting close to the gumline, can add to this too, pulling the lip up as you smile.
How Is a Gummy Smile Diagnosed?
Since each of those causes needs a different fix, it’s worth getting a proper look before deciding anything. Most people start with their general dentist or a Specialist Periodontist, who’ll check how much gum shows on a full smile, where the gumline actually sits, and whether lip movement or jaw position is the bigger factor.
If tooth position turns out to be the main driver, you’d then be referred on to a Specialist Orthodontist for that specific piece.
How Is a Gummy Smile Treated?
What works depends entirely on what’s causing it. There’s no one-size-fits-all fix here.
-
Gum contouring
When the gum tissue is simply covering more tooth than it should, reshaping the gumline tends to be the most direct fix. It’s a minimally invasive, in-clinic procedure done by a Specialist Periodontist. Gum contouring walks through exactly how it works, what recovery feels like, and who performs it at our centers.
-
Orthodontic treatment
If tooth position or a mild bite issue is behind it, a Specialist Orthodontist can gradually move the teeth and gumline into place. It takes longer than other options, but there’s no surgery involved.
-
Lip repositioning surgery
When a hyperactive upper lip is the cause, this procedure limits how far the lip travels upward on a smile. Case reports describe good results, though outcomes depend heavily on surgical technique and some relapse within the first year has been reported — it’s not right for every case.
-
Orthognathic (jaw) surgery
For a more noticeable vertical maxillary excess, repositioning the jaw surgically may be the recommended route. It’s the most involved option on this list, reserved for cases where the skeletal difference is significant, and it would mean a referral to an Oral & Maxillofacial Surgeon for a proper evaluation.
More often than not, it’s a mix of causes, and the treatment reflects that — gum contouring paired with lip repositioning, for example. That’s really why the evaluation matters more than guessing at a single cause.
If you’re thinking about treatment, a consultation is the way to find out which of these actually fits your situation.

Frequently Asked Questions
Not usually. It’s mostly a cosmetic thing tied to gum tissue, tooth position, lip movement, or jaw structure, not a sign of disease. Still, a dental check is the right way to know which factor applies to you.
No. Whatever’s causing it, gum, bone, or muscle, doesn’t really change on its own once you’re an adult. Treatment is what changes it, not time.
Most patients describe it as mild discomfort rather than pain, and it’s managed with local anesthetic during the procedure. Gum contouring goes into more detail on what recovery actually feels like.
Most gummy smile treatment is classified as cosmetic, so it’s rarely covered by insurance. There are occasional exceptions where a related functional issue is involved, so it’s still worth checking.
