Dental term explained

Gingivectomy

Gingivectomy removes selected gum tissue for disease management, access or contouring without necessarily reshaping supporting bone.

It differs from crown lengthening that may include bone adjustment. A useful question to ask your dentist: “Is only soft tissue being changed, and how will the final contour affect cleaning or restoration?”

A question that makes the term useful

“Is only soft tissue being changed, and how will the final contour affect cleaning or restoration?”

Full explanation

In depth

A gingivectomy is the surgical removal of gum tissue to reshape the gum line. It is performed for two quite different reasons. Knowing which applies to you changes the conversation entirely. Therapeutically, it removes overgrown or diseased tissue that cannot be maintained: for example where medication has caused gum overgrowth, or where a pocket cannot be cleaned. Cosmetically, it reshapes the gum line to address a gummy smile or teeth that appear short because gum covers more of them than it should. The critical planning question in the cosmetic case is whether bone also needs recontouring; where it does, the procedure becomes crown lengthening instead of a soft-tissue gingivectomy, with a longer healing period. A gummy smile can also result from a short or highly mobile upper lip, or from vertical growth of the upper jaw, neither of which removing gum tissue will correct, which is why establishing the actual cause should precede any procedure aimed purely at appearance.

Also called: gum reshaping, gum contouring, gingival recontouring, gum lift.

Two purposes

Therapeutic and cosmetic indications

FactorDetail
Gum overgrowthCertain medications are associated with gingival enlargement that can make cleaning impossible and may need surgical reduction.
Pocket reductionRemoving tissue so a pocket that cannot be cleaned becomes accessible and maintainable.
Gummy smileReshaping the gum line where excess tissue makes teeth appear short. Requires assessment of why the smile appears gummy.
Delayed passive eruptionWhere gum has not receded to its normal position, leaving teeth looking short with tissue that can be reshaped.
Access for restorative workExposing tooth structure so a restoration margin can be placed and cleaned properly.
Where bone is involvedIf bone must also be recontoured, the procedure is crown lengthening: a different operation with different healing.

Assessment

Why the cause of a gummy smile matters

A smile can appear gummy for several reasons, and they need different treatments. Excess gum tissue is one. A short upper lip or a lip that lifts unusually high is another. Vertical growth of the upper jaw is a third, and that may need orthodontic or surgical management instead of gum surgery. Removing tissue where the cause is skeletal or muscular will not produce the intended result. This is why an assessment establishing the cause should precede a procedure aimed at the appearance.

Ask specifically whether bone recontouring is needed. That single question distinguishes a gingivectomy from crown lengthening. The two differ substantially in healing time and in how the final result settles.

Practicalities

What to establish before treatment

  1. What is the cause of the appearance or the tissue problem being treated?
  2. Is bone recontouring required, making this crown lengthening, not a gingivectomy?
  3. How long before the tissue settles into its final position, particularly if restorations are planned afterwards?
  4. Is the tissue likely to grow back. Relevant where medication-associated overgrowth is the cause?
  5. Will the underlying medication or cause be addressed, or will the problem recur?
  6. What does the result depend on, and what would be done if the tissue heals asymmetrically?

Questions people ask

Common questions

01

Will my gums grow back?

It depends on the reason for the surgery. Where overgrowth was caused by a medication that continues, recurrence is a genuine possibility and managing the underlying cause matters as much as the surgery. Where tissue was reshaped for a cosmetic reason and the cause is not ongoing, the result is generally more stable. Ask specifically about recurrence in your situation. The answer differs substantially.

02

Is this the same as crown lengthening?

Not quite. The distinction matters. A gingivectomy removes soft tissue only. Crown lengthening also recontours the bone beneath, which is necessary where the bone level determines how much tooth can be exposed. Crown lengthening involves a longer healing period before restorations can be made. Asking which procedure is planned tells you what to expect from the timeline.

03

How long does it take to heal?

Soft tissue healing after a gingivectomy is generally quicker than after a procedure involving bone, but the tissue continues to settle for a period afterwards. Where restorations are planned, that settling period matters. Placing a margin before the tissue has stabilized risks the result changing afterwards. Ask what interval is planned before any restorative work begins.

04

Will it fix my gummy smile?

Only if excess gum tissue is actually the cause. A gummy appearance can also result from a short or highly mobile upper lip, or from vertical growth of the upper jaw. Neither is corrected by removing gum. An assessment should establish the cause first. If gum surgery is proposed without that assessment, asking what is causing the appearance is a reasonable and important question.

05

Is it covered by insurance?

It depends heavily on the indication. Treatment of gum overgrowth or a periodontal problem is assessed differently from a procedure performed for appearance, which is commonly excluded as cosmetic. The procedure code and the documented reason drive the determination. A pretreatment estimate is worthwhile here, since the same procedure can be covered or excluded depending on why it is being done.

06

Can a gingivectomy be performed using a laser instead of a scalpel, and does that change recovery?

Yes, laser gingivectomy is a recognized technique some practices offer, and it can offer some advantages in bleeding control during the procedure, though overall healing time and the underlying principle of removing tissue to the planned shape remain fundamentally similar regardless of instrument. The choice between laser and traditional technique is more about a practice's specific equipment and preference than a dramatic difference in outcome for you.

07

Is it normal to have difficulty eating normally for a few days after a gingivectomy?

Yes, some tenderness and sensitivity around the treated area commonly makes chewing on that side less comfortable for the first few days, so a softer diet during that period is typically advised, and this is an expected part of soft-tissue healing instead of a sign of a problem.

08

Can gum tissue removed during a gingivectomy for a gummy smile grow back and undo the cosmetic result over time?

If the underlying cause was purely excess tissue with no ongoing driver like a specific medication, the result is generally stable long-term, but where an ongoing cause such as continued medication-associated overgrowth is present, some regrowth is a genuine possibility, which is exactly why addressing or at least understanding the underlying cause is part of a durable outcome instead of the surgery alone.

09

How is it decided how much gum tissue to remove during a cosmetic gingivectomy?

Planning typically involves measuring the specific amount of excess tissue relative to an ideal, aesthetically balanced gum line, sometimes using a surgical guide based on photographs or a digital smile design, so the amount removed is a planned, measured decision, not an estimate made freehand during the procedure itself.

10

Is a gingivectomy performed on just one tooth, or is it usually done across several teeth at once for a more even result?

It depends on the indication: a therapeutic gingivectomy addressing a specific isolated problem, like an unreachable pocket on one tooth, may be limited to that tooth, while a cosmetic gingivectomy for an uneven or gummy smile is typically planned across several front teeth together specifically to achieve a symmetrical, balanced result instead of treating one tooth in isolation.

11

Does a gingivectomy performed for medication-related gum overgrowth need to be repeated if the medication is continued long-term?

It can: if the causative medication continues, some degree of overgrowth can recur over time, which is why managing the underlying cause, potentially in coordination with the prescribing physician about whether an alternative medication is possible, is discussed alongside the surgery itself instead of the surgery alone being expected to provide a permanent solution.

12

Can a gingivectomy be combined with teeth whitening or veneers in the same overall treatment plan for a smile makeover?

Yes, this is a common sequence for a comprehensive cosmetic plan. The gum reshaping is typically done first and allowed to heal and stabilize before whitening or veneers proceed, since the final gum position needs to be settled before shade selection or veneer margins are finalized against it.
