Gingivoplasty: what it is, who it suits, recovery and limits

Gingivoplasty is a minor procedure that reshapes the gum line so it looks more balanced and shows more of the tooth. It is mainly indicated when gum tissue covers too much of the teeth, when one tooth's gum line sits lower than its neighbor's, or when the contour needs adjusting before veneers. It is done under local anesthesia in the dental office, and recovery is usually smooth.

The most important point, and one that is rarely explained, is that gingivoplasty does not fix every kind of "too much gum showing." If the cause lies in the bone, the lip or the position of the teeth, removing gum tissue alone may not work, and the gum tends to grow back. That is why the decision comes from an exam, not from a photo of the smile.

In this article, Dr. Cléo Salustiano (CRO-SP 170844) explains when gingivoplasty makes sense, how the procedure works, what to expect during recovery and which cases need a different approach. If your end goal is veneers, it is also worth reading about gum health before veneers and whitening.

This article comes from Dr. Cléo Salustiano's dental office in Mooca, São Paulo (care in English, Portuguese and Spanish). See the gum health page to learn how the treatment is done here and book your assessment.

How is gingivoplasty done, and when is it indicated?

Gingivoplasty is done by removing and shaping a thin strip of gum tissue along the edge of the teeth, under local anesthesia, until the planned contour is reached. Before any incision, the dentist measures how much gum sits above the bone on each tooth, using a gentle probe and, when needed, an X-ray or CT scan. That measurement shows whether gum tissue can be removed without invading the space the gum needs to stay healthy.

There are three common indications. The first is a gummy smile caused by excess gum tissue, when the teeth look short because the gum covers part of them. The second is asymmetry: one tooth with a lower gum line than the one next to it, which draws attention in the smile. The third is preparation for veneers, ultra-thin veneers or crowns, when the gum line needs adjusting so the cosmetic work looks proportional. Gums can also become enlarged from inflammation or from certain medications, but in those cases the inflammation is treated first, and the gum often shrinks back without surgery.

The procedure itself is usually quick when only a few teeth are involved. It can be done with a scalpel, a laser or electrosurgery, depending on the case and the clinician's technique. The new contour is planned in advance, considering tooth shape, the smile line and symmetry between both sides. No one can promise an exact number of millimeters: the limit is what that patient's gum and bone allow.

Here is the main limit. When the gum sits very close to the bone, or when bone itself covers part of the tooth crown, removing gum alone is not enough: it tends to grow back to the distance the body treats as natural. In those cases, a different procedure is indicated, crown lengthening with bone recontouring, which is a broader periodontal surgery. And if the extra gum showing comes from a lip that rises more than usual, from vertical overgrowth of the upper jawbone or from tooth position, the answer lies in other treatments, such as orthodontics or jaw surgery, and gingivoplasty may play no role at all.

In short, gingivoplasty is indicated when the problem really is excess gum tissue, with healthy gums and enough space down to the bone. A gum health assessment is what tells these scenarios apart, and it is common to find that a case calls for a combination of steps rather than a single procedure.

What is recovery like, and how should you care for your gums afterward?

Recovery from gingivoplasty is usually smooth: most people feel mild discomfort for the first few days, managed with the medication the dentist recommends, and get back to their routine quickly. The gum is tender and red at first, and surface healing usually happens within the first weeks. The final contour, however, takes longer to settle, and that time varies from person to person.

For the first few days, the usual advice is to choose soft, lukewarm or cold foods, avoid very hot, acidic, spicy or hard foods on that side, avoid smoking and skip alcohol. Brushing continues, but with a soft brush and extra care around the treated area, following exactly what you were told, sometimes with a mouthwash recommended for that period. Touching the area with your tongue or fingers slows healing.

If the plan includes veneers, ultra-thin veneers or crowns afterward, the gum needs to stabilize before the final work. If composite or porcelain is placed on a gum that is still settling, the edge may show later. The waiting time is set during follow-up, by looking closely at the gum, not by a fixed deadline that applies to everyone.

Contact your dentist before the scheduled follow-up if you notice bleeding that does not stop with light pressure, swelling that increases after the third day, fever, or pain that gets worse instead of easing over the days. These situations are uncommon, but they should be checked.

In the long run, the result depends on keeping the gums healthy. Good brushing, flossing and regular cleanings help prevent inflammation, which can change the contour over time. In clinical practice, patients who keep up their hygiene routine often maintain a stable contour for many years, but no one can predict exactly how each person's gums will behave.
