Gum Contouring: Fixing a Gummy Smile or Uneven Gum Line

The basic process involves a dentist or periodontist removing small amounts of gum tissue, sometimes using a scalpel, sometimes using a laser, along the gum line to reveal more of the tooth's crown and create a more even, symmetrical appearance across your smile. It's typically done under local anesthesia and doesn't involve any change to the teeth themselves — the teeth are already fully formed underneath; the gum tissue is simply covering more of them than proportion would call for.

### What Causes Uneven Gums?

A few different things can lead to a gummy smile or uneven gum line. Genetics play a significant role — some people are simply born with a gum line that sits lower on the teeth than average. Certain medications, particularly some used for blood pressure or seizure control, can cause gum tissue to grow more than usual, a condition sometimes called gingival hyperplasia. A tooth that erupted only partially, leaving more gum tissue covering it than typical, can also create unevenness in specific spots rather than across the whole smile. And in some cases, a naturally short upper lip combined with a completely normal gum line can create the visual impression of a gummy smile even when the gum tissue itself is proportionate — which is actually an important distinction, since it changes what kind of treatment would actually help.

### Conditions Treated With Gum Contouring

Beyond purely cosmetic gumminess, gum contouring is sometimes used to correct gum tissue that's grown excessively due to certain medications, to even out a gum line where some teeth show more gum than others due to uneven eruption, or as part of preparing a tooth for a crown or other restoration where excess gum tissue is in the way of getting a proper fit.

Usually not — most gum contouring is elective and purely cosmetic, done because a person wants to change how their smile looks rather than to address a health problem. That said, there are situations where it crosses into medical necessity, such as correcting gum overgrowth caused by medication that's affecting oral hygiene or comfort, or as a functional step before another dental procedure that requires better access to the tooth structure. It's worth discussing directly with your dentist which category your specific situation falls into, since this can affect whether any part of the procedure might be covered by insurance.

Gum contouring can be performed by a general dentist trained in the procedure, though more complex cases, or cases involving significant tissue removal, are often referred to a periodontist — a dentist who specializes specifically in the gums and supporting structures of the teeth. If your case is more involved, or if you have a history of gum disease that needs to be factored into the treatment plan, a periodontist referral is common and reasonable.

### Before Gum Contouring

Your dentist or periodontist will examine your gum line, sometimes using photos or a digital mock-up to plan exactly how much tissue to remove and where, to achieve a natural, symmetrical result rather than an uneven or overcorrected one. This planning stage matters more than people expect, since the goal is a gum line that looks like it was always meant to be there, not an obviously "done" appearance.

### During Gum Contouring

Local anesthesia is used to numb the treatment area. The excess gum tissue is then removed and reshaped, either with a traditional scalpel or a soft-tissue laser, depending on the provider's preferred technique and your specific case. The procedure is usually completed within a single visit, often in well under an hour depending on how many teeth are involved.

### After Gum Contouring

Most patients experience mild swelling and some tenderness for a few days afterward, generally manageable with over-the-counter pain relief. A soft diet is often recommended for the first several days to avoid irritating the healing tissue.

Laser-based gum contouring has become a common alternative to traditional scalpel techniques, and it comes with a few genuine practical advantages. Lasers tend to cause less bleeding during the procedure since they cauterize tissue as they cut, which can also mean a somewhat more comfortable recovery for some patients. Healing time with laser techniques is sometimes shorter than with traditional methods, though this varies by individual case and by how much tissue is being reshaped. Not every provider offers laser gum contouring, so it's worth asking directly if this is something you're specifically interested in.

For gummy smiles caused primarily by an overactive upper lip muscle — one that lifts higher than average when smiling, exposing more gum regardless of where the actual gum line sits — Botox injections into that specific muscle can reduce how high the lip rises, decreasing how much gum shows without touching the gum tissue itself at all. This is a fundamentally different approach from gum contouring, addressing muscle behavior rather than gum tissue, and it's temporary, typically needing to be repeated every several months as the effect wears off. It's worth having your specific case properly evaluated to determine whether your gumminess comes from excess gum tissue, an overactive lip muscle, or some combination of both, since that determines which treatment — or combination of treatments — would actually address your specific situation.

Crown lengthening is a related but distinct procedure, sometimes involving not just gum tissue but also a small amount of underlying bone, used when more of the tooth structure needs to be exposed than gum reshaping alone can achieve — often because a tooth needs more visible surface for a crown or other restoration to be properly placed, or because the gumminess involves excess bone height in addition to excess gum tissue. Gum contouring alone addresses soft tissue only. If your case involves bone as well, crown lengthening is the more appropriate procedure, and this distinction is exactly what your dentist's initial examination is meant to determine.

The most obvious benefit is a more proportional, symmetrical smile, which for a lot of people translates into real, lasting confidence in social situations where they might have previously felt self-conscious. It's also a relatively quick procedure with minimal downtime compared to more invasive cosmetic or restorative treatments, and results are typically visible almost immediately, with final healing completing over the following weeks.

As with any minor surgical procedure, there's a small risk of infection at the treatment site, though this is uncommon with proper aftercare. Some swelling, tenderness, and minor bleeding in the days following the procedure are normal and expected, not complications in themselves. There's also a possibility, though relatively rare with a skilled provider, of gum tissue not healing perfectly symmetrical, which can sometimes require a minor touch-up procedure to fully even out.

### Recovery Tips

Sticking to soft foods for the first several days helps avoid irritating the healing gum tissue. Gentle oral hygiene, avoiding vigorous brushing directly over the treated area initially, while still keeping the rest of your mouth clean, is typically recommended. Avoiding smoking during the healing period is also advised, since it can slow healing the same way it does with other oral procedures.

### When You Can Return to Work or School

Most people return to normal daily activities, including work or school, within a day or two, since the procedure itself is minor and doesn't typically require significant downtime. Some mild visible swelling in the first day or two is common, which is worth factoring in if you have an event or important commitment very soon after your procedure.

Cost varies based on how many teeth are involved, whether a laser or traditional technique is used, and your geographic location. Because gum contouring is usually considered a cosmetic procedure, dental insurance typically doesn't cover it unless there's a specific medical justification, such as correcting medication-related gum overgrowth, in which case partial coverage may apply. It's worth asking your provider directly for an itemized quote before proceeding, since pricing can vary noticeably between practices.

Does gum contouring hurt? The procedure itself is performed under local anesthesia, so you shouldn't feel significant pain during treatment. Afterward, mild soreness and tenderness are common for a few days, generally manageable with over-the-counter pain relief, similar to recovering from a minor dental procedure.

Is gum contouring permanent? Generally, yes. Once excess gum tissue is removed, it typically doesn't grow back to its previous level under normal circumstances. That said, certain factors — like starting a new medication known to cause gum overgrowth — could affect results over time, which is worth discussing with your dentist if it applies to your situation.

Is gum contouring worth it? For people genuinely bothered by a gummy smile or uneven gum line, many find the relatively quick procedure and short recovery well worth the boost in confidence it provides. Since it's a personal, cosmetic decision, "worth it" really comes down to how much the current appearance bothers you weighed against the cost and minor recovery involved.

Can gum contouring fix a gummy smile caused by a short upper lip? Not on its own, since gum contouring addresses gum tissue, not lip position or movement. If a short or highly mobile upper lip is the main cause of your gummy smile, Botox or, in some cases, a surgical lip repositioning procedure may be more appropriate, sometimes combined with gum contouring if excess gum tissue is also part of the picture.

How long do the results of gum contouring last? For purely cosmetic gum reshaping unrelated to medication or other ongoing causes, results are generally long-lasting and don't require the touch-ups that something like Botox for a gummy smile would need. If gum overgrowth is being caused by an ongoing factor, like a specific medication you continue taking, some regrowth is possible over time, which is worth discussing with your provider if it applies to you.
