What Is a Gingivectomy? Gum Removal Surgery Explained by a Periodontist

If your dentist or periodontist has used the word "gingivectomy," it probably sounded more alarming than it is. A gingivectomy is the surgical removal of a small amount of gum tissue. It is one of the oldest and most predictable procedures in periodontics, and today it is often done with a laser, with minimal discomfort and a short recovery.

As a Yale-trained periodontist, I perform gingivectomies for two very different reasons: to treat gum overgrowth and certain periodontal pockets, and to reshape the gumline for function or appearance. This article explains what a gingivectomy is, when it is the right choice and when it is not, what the procedure and healing look like, and how it differs from similar-sounding procedures such as gingivoplasty and crown lengthening.

What Is a Gingivectomy?

The word breaks down simply: "gingiva" means gum, and "-ectomy" means surgical removal. A gingivectomy removes part of the gum tissue that sits over the teeth. The goal is either to eliminate excess gum that is trapping bacteria and plaque, or to expose more of the natural tooth so that it can be cleaned, restored, or displayed properly.

A related procedure, gingivoplasty, reshapes the gum without necessarily removing much tissue. The two are frequently done together, and many patients (and some websites) use the terms interchangeably. In practice, gingivectomy removes tissue, while gingivoplasty contours it so that the gumline looks natural and is easy to keep clean.

When Is a Gingivectomy Needed?

Gum overgrowth (gingival enlargement)

Gums can thicken and grow over the teeth for several reasons. Some medications are well-known causes, including certain anticonvulsants (phenytoin), calcium channel blockers used for blood pressure (such as nifedipine and amlodipine), and cyclosporine used after organ transplantation. Hormonal changes during puberty and pregnancy, mouth breathing, orthodontic appliances, and chronic plaque-induced inflammation can also produce enlarged gums. Rarely, hereditary gingival fibromatosis causes thick, fibrous overgrowth.

Overgrown gums create "pseudopockets," which are deep-looking spaces that are not caused by bone loss but are still very hard to clean. Plaque collects, inflammation worsens, and the overgrowth often gets worse. Removing the excess tissue returns the gumline to a cleanable shape.

Certain periodontal pockets

In periodontal disease, pockets form between the tooth and gum. Most true pockets, where the bone has been lost, are treated with deep cleaning, laser therapy, or regenerative surgery rather than with gum removal. A gingivectomy is appropriate mainly when the pocket is due to excess gum tissue, the bone level is healthy, and there is enough firm, attached gum that removing some will not leave the tooth exposed. For true bone-loss pockets, the modern approach is to preserve tissue, not cut it away. That is the reason I often recommend LANAP laser therapy instead, which treats deep pockets without cutting or suturing.

A "gummy" smile caused by excess gum

When teeth are covered by too much gum tissue, they look short and the smile shows a lot of pink. If the cause is gum tissue alone and the bone sits at a normal level, gingivectomy with gingivoplasty can restore the natural proportions of the teeth. If the cause is bone position, jaw growth, or lip movement, a different approach is needed. Our article on the gummy smile fix covers how that diagnosis is made.

Making room for a restoration

When a tooth is broken at the gumline or decay extends below the gum, a dentist may need more exposed tooth structure to place a filling or crown that seals properly. If a small amount of gum tissue is the only obstacle, gingivectomy can help. If the crown margin would end up too close to the bone, crown lengthening is the right procedure instead. See crown lengthening before a crown and functional versus cosmetic crown lengthening for the difference.

Uneven or irregular gumlines

Some patients have one tooth with a much lower gumline than its neighbors, or ragged gum edges after orthodontic treatment. Gingivoplasty can even out the contour. For recession, where gum has been lost, the answer is the opposite: adding tissue with gum grafting, not removing it.

When a Gingivectomy Is Not the Right Choice

The honest answer is that gingivectomy is used less often today than it was decades ago, because it is easy to overuse. I would steer a patient away from it when:

• There is bone loss. Removing gum over a bone defect hides the problem and sacrifices tissue you may need. Bone defects are treated by cleaning and, where possible, rebuilding with bone regeneration.
• There is very little attached gum. Attached gum is the firm, pink band that anchors around the tooth. Removing too much can lead to recession, sensitivity, and an unstable gumline.
• The gum looks "too long" because the teeth are worn. Teeth that have worn down from grinding can look short even though the gum is normal. Treating the wear is the real fix. See our article on grinding for how grinding affects the mouth.
• An underlying cause has not been addressed. If medication, plaque, or mouth breathing caused the overgrowth, gum tissue will return unless the cause is managed.

A thorough exam, periodontal probing, and a 3D scan or X-rays show whether the problem is gum alone or gum plus bone. That distinction determines the procedure.

What Happens During a Gingivectomy

A gingivectomy is typically an in-office procedure under local anesthetic. Most patients are comfortable and awake, and sedation is available for anxious patients (see our overview of sedation dentistry options).

1. Evaluation and planning. We measure gum thickness, pocket depth, and the position of the bone, and mark exactly how much tissue will be removed. Careful planning is what prevents over-removal.
2. Numbing. The area is anesthetized so that you feel pressure but not pain.
3. Tissue removal. The excess gum is trimmed along a planned, beveled line using a scalpel, an electrosurgery unit, or a dental laser. Lasers seal small blood vessels as they cut, which usually means less bleeding and often less swelling.
4. Contouring. The gum edge is shaped (gingivoplasty) so that it tapers naturally to the tooth and follows the correct scalloped pattern.
5. Protection. Some cases receive a thin protective dressing, while laser cases often need none. Sutures are usually not required because the wound heals from the surface.

A single area can take as little as 15 to 30 minutes. Treating several teeth, or the whole smile line, takes longer. Our practice uses laser technology throughout the office, and you can read more about it on our laser dentistry page.

Scalpel vs. Laser Gingivectomy

Both can deliver an excellent result in skilled hands. The practical differences are:

• Scalpel: precise and inexpensive, but bleeding is greater and a dressing is often used.
• Laser: controlled bleeding, a clearer field, and usually less post-operative discomfort. The tradeoff is that heat must be managed carefully near the tooth and bone, which is why technique and training matter more than the device itself.

The laser is a tool, not a guarantee. What determines the outcome is the diagnosis and the planning. A well-planned scalpel gingivectomy beats a poorly planned laser one every time.

Gingivectomy Recovery: What to Expect

Because the wound is left open to heal rather than closed with sutures, healing is gradual but typically straightforward.

• First 24 to 48 hours: mild soreness and light oozing are normal. Over-the-counter pain relievers usually are enough.
• Days 3 to 7: the surface looks whitish or yellow as a protective layer forms, and soreness fades. This is normal and not a sign of infection.
• Weeks 1 to 2: the surface tissue covers the area and most patients return to normal comfort. Many go back to work the next day.
• Weeks 4 to 6: the gum matures, and the final contour and color become apparent. Complete maturation of the tissue can take a few months.

Practical tips for a smooth recovery:

• Eat soft, cool foods for several days and avoid spicy, crunchy, or very hot items. Our guide on gum surgery recovery has useful food ideas that apply here too.
• Rinse gently with warm salt water or a prescribed rinse after the first day.
• Keep the area clean with a soft brush, and avoid aggressive brushing right at the surgical site for the first week.
• Avoid smoking and vaping, which delay healing considerably.
• Call us if you have heavy bleeding that does not stop with pressure, worsening pain after day three, swelling that increases, or fever.

Risks and Limitations

Gingivectomy is safe when properly planned, but it is not risk-free. Possible issues include bleeding, temporary sensitivity to temperature, slower healing in smokers or people with uncontrolled diabetes, and, if too much tissue is removed, permanent recession or exposed root surfaces. Removed gum does not grow back to its original position, so conservative planning is essential. It is better to remove a little less and refine later than to take too much.

Gum overgrowth caused by medication can recur. If you take a medication that causes overgrowth, we coordinate with your physician where appropriate, because sometimes an alternative drug can be used. Meticulous home care and regular periodontal maintenance reduce the chance that tissue returns.

Gingivectomy vs. Similar Procedures

• Gingivectomy: removes excess gum tissue. No bone is changed.
• Gingivoplasty: reshapes and contours the gum. Often performed together with gingivectomy.
• Crown lengthening: removes gum and, when needed, reshapes bone to expose more tooth. Used when bone is the limiting factor.
• Cosmetic gum contouring: a gum reshaping approach used to improve smile proportions.
• Gum grafting: the reverse of a gingivectomy. It adds tissue to cover receded roots.
• LANAP: a laser treatment for periodontal disease that preserves gum tissue and encourages reattachment instead of trimming gum away.
