A gum graft is an outpatient procedure where tissue is placed over areas where your gums have receded, covering exposed tooth roots and rebuilding the gumline. The surgery typically takes one to two hours, is performed under local anesthesia, and involves harvesting tissue from the roof of your mouth (or using donor material) and attaching it to the recession site. Most people return to normal activities within one to two weeks.
Why Gum Grafts Are Performed
Gum recession exposes the roots of your teeth, which aren’t protected by enamel the way the crowns are. This can cause sensitivity to hot and cold, increase the risk of decay at the root surface, and eventually compromise the tooth’s stability. Recession happens gradually, often from aggressive brushing, gum disease, genetics, or teeth grinding, and it doesn’t reverse on its own.
Periodontists evaluate recession severity to determine whether grafting is appropriate and how much root coverage you can expect. Mild to moderate recession where the bone and tissue between your teeth is still intact offers the best outlook, with full root coverage often achievable. More advanced cases, where bone loss has occurred between the teeth, typically achieve partial coverage. Recession so severe that both bone and soft tissue between teeth are largely gone may not be a candidate for grafting at all.
Types of Gum Grafts
The most common type is a connective tissue graft. Your periodontist removes a layer of tissue from beneath the surface of the roof of your mouth and places it under the gum tissue at the recession site. Because the transplanted tissue sits beneath the outer layer of your gums, it blends in with the surrounding color and texture, making it the preferred option when appearance matters. It’s also the go-to choice for more significant recession.
A free gingival graft takes tissue directly from the surface of the palate rather than from underneath it. This approach requires less tissue overall and allows for more precise, smaller adjustments. It’s often used when the goal is to thicken thin gum tissue rather than cover a large area of exposed root.
In some cases, your own tissue isn’t used at all. Allografts use processed human donor tissue, while xenografts use processed animal tissue. Both eliminate the need for a second surgical site on the roof of your mouth, which reduces discomfort. Your periodontist will recommend a tissue source based on the size of the area being treated, the thickness of your existing tissue, and your overall health.
Step by Step: What Happens During Surgery
The procedure begins with local anesthesia to numb the graft site and, if tissue is being harvested from your palate, the roof of your mouth. Many periodontists also offer sedation options like nitrous oxide, oral sedation, or IV sedation if you want to feel more relaxed during the procedure.
Once you’re numb, the periodontist prepares the recipient site. For a connective tissue graft, this involves making a small partial-thickness incision around the area of recession and creating a pouch or flap in the gum tissue. This pouch is carefully separated from the underlying bone and root surface, creating a space where the new tissue will be placed.
Next comes the donor tissue. If tissue is being taken from your palate, the periodontist makes an incision on the roof of your mouth and removes a strip of connective tissue from beneath the surface layer. The surface layer is then sutured closed. If donor material is being used instead, this step is skipped entirely.
The harvested tissue is positioned inside the pouch over the exposed root and sutured into place with gentle tension. The goal is full contact between the graft and the root surface so that blood vessels can grow into the new tissue and integrate it. The outer gum flap is then repositioned over the graft and sutured shut. The entire process typically takes 60 to 90 minutes for one or two teeth.
The Pinhole Technique: A Minimally Invasive Alternative
The Pinhole Surgical Technique is a newer approach that skips incisions and sutures. Instead of transplanting tissue, the periodontist makes a tiny, pinhole-sized entry point in the gum and uses specialized instruments to loosen the existing tissue. The loosened tissue is then gently repositioned downward (or upward, for lower teeth) to cover the exposed roots. Small collagen strips are placed through the pinhole to stabilize the tissue and support healing.
The advantages are notable. Healing takes days rather than weeks, discomfort is minimal compared to traditional grafting, and multiple teeth can be treated in a single session. The aesthetic improvement is essentially immediate. Traditional grafting, by contrast, is often limited to one or two teeth per session and involves moderate discomfort during the recovery period. Not every case of recession is suitable for the pinhole technique, so your periodontist will assess whether the approach is right for your situation.
What Recovery Looks Like
The first two to three days are the most restrictive. You should avoid any strenuous physical activity to prevent heavy bleeding. Do not use a straw, as the suction can dislodge the blood clot that protects the surgical site. Eat soft foods and avoid anything hard, crunchy, or very hot. Don’t spit or rinse forcefully.
Oral hygiene around the graft site changes significantly. You’ll be told to avoid brushing and flossing the surgical area entirely. Instead, your periodontist may recommend using a soft cotton swab with toothpaste to gently clean tooth surfaces near the graft. You can brush the rest of your mouth normally. One of the most important instructions is simply to leave the area alone: don’t pull your lip or cheek to look at it, don’t touch it with your fingers, and don’t probe it with your tongue. Disturbing the graft during early healing is one of the most common reasons it fails.
Most people feel significantly better within a week, and the tissue continues maturing over the following months. The palate donor site, if applicable, heals on its own but can be sore for several days. Over-the-counter pain relief is usually sufficient for managing discomfort at both sites.
Success Rates and Long-Term Results
Gum grafts have strong success rates. A study following 39 patients across 66 recession sites found an average root coverage of 86.2% overall, and results improved with time. At 12 months, root coverage averaged about 73%, but by five years or longer it reached approximately 98%, with over three-quarters of patients in that group achieving complete root coverage. Shallower recessions (1 to 3 mm) had the best outcomes at around 88% coverage, while deeper recessions exceeding 6 mm still achieved about 80%.
The severity classification of your recession matters. Cases where the bone between teeth is intact routinely achieve full coverage. Even more advanced recession with some bone loss between teeth can reach around 86 to 90% root coverage, which is enough to protect the root, reduce sensitivity, and improve the appearance of the gumline.
Signs the Graft Isn’t Healing Properly
Some swelling, mild bleeding, and discomfort in the first few days are normal. What isn’t normal is pain or throbbing that gets worse instead of better, or tissue that looks grayish, feels dead, or starts peeling away from the tooth. If you notice the graft feeling loose or shifting when you eat or talk, it may not be attaching. Swelling accompanied by pus, a foul taste, or an odor around the site points to infection.
The most common culprits behind graft failure are things within your control: brushing the area too soon, eating hard foods before the tissue stabilizes, pulling your lip to check on the site, or skipping prescribed rinses and medications. Smoking is a major risk factor because it reduces blood flow to the healing tissue. Certain medications and conditions like diabetes can also slow the process. If the graft does fail, the gum will continue receding and the procedure can typically be repeated once the area has healed.
