A gum graft is a dental surgery that repairs gum recession by adding tissue to areas where your gums have pulled back and exposed tooth roots. The procedure covers those roots back up, protecting them from decay, reducing sensitivity, and preventing further tissue loss. It’s one of the most common periodontal surgeries, typically performed by a periodontist (a dentist who specializes in gums) under local anesthesia.
Why Gum Grafts Are Needed
Gum recession happens gradually. You might notice your teeth look longer than they used to, feel a notch near the gumline with your fingernail, or experience sharp sensitivity to hot or cold drinks. Once gum tissue pulls away from a tooth, it doesn’t grow back on its own. The exposed root is softer than enamel and more vulnerable to decay, and the recession tends to worsen over time without treatment.
Not every case of recession requires surgery. When there’s still adequate tissue thickness and height around the tooth, preventive measures like adjusting brushing technique or treating grinding habits may be enough to keep things stable. Surgery becomes the recommended option when the recession is progressing, when root sensitivity is significant, or when there’s a risk of tooth loss or bone loss down the line. Cosmetic concerns in visible areas are another common reason people pursue the procedure.
Types of Gum Grafts
The three main approaches differ in where the replacement tissue comes from and how it’s placed.
- Connective tissue graft: The most common type. Your periodontist takes a small piece of tissue from beneath the surface of the roof of your mouth, then stitches it over the exposed root. This approach achieves the best root coverage results, with studies showing it covers about 86% of exposed root surface on average. It’s considered the gold standard for most recession cases.
- Free gingival graft: Instead of tissue from beneath the surface, a thin strip is taken directly from the surface of the palate. This type is best for building up a thicker band of gum tissue rather than specifically covering roots. It works well on lower front teeth and other non-visible areas, since the color match isn’t as seamless. Multiple teeth can be treated at once.
- Pedicle graft: Rather than harvesting tissue from your palate, the periodontist uses gum tissue from right next to the affected tooth, rotating or sliding it over to cover the exposed root. This only works when there’s enough healthy tissue adjacent to the recession site.
Your Own Tissue vs. Donor Tissue
Most gum grafts use your own tissue, harvested from the roof of your mouth. This is considered the gold standard because the tissue integrates reliably and contains living cells that promote healing. The trade-off is a second surgical site in your mouth, which adds to post-operative discomfort.
Processed donor tissue (from a tissue bank) is an alternative that eliminates the need for a palate harvest. It means less pain and a shorter procedure. Research on bone grafting with donor material shows comparable shrinkage rates over 12 months (about 14% for donor tissue vs. 12.5% for your own tissue), with no significant differences in outcomes. For gum grafts specifically, connective tissue from your own palate still tends to produce more predictable long-term root coverage, but donor tissue remains a reasonable option depending on your situation.
What the Procedure Feels Like
The surgery itself is painless because of local anesthesia. You’ll feel pressure and movement but no sharp pain. Most gum grafts treat one to a few teeth at a time, and the procedure is done in a single office visit.
After the anesthesia wears off, you can expect soreness at both the graft site and the palate (if tissue was harvested there). A study of 330 periodontal surgeries found that 70% of patients reported only mild pain, while about 30% experienced moderate to severe discomfort. The average duration of pain was 2 days. Over-the-counter pain relievers like ibuprofen or acetaminophen handle it for most people, though your periodontist may prescribe something stronger if needed.
Recovery Timeline
Full healing takes 6 to 8 weeks, but the most restrictive phase is the first two weeks. Here’s what to expect:
During the first one to two weeks, you’ll eat only soft foods and avoid chewing anywhere near the graft site. Think yogurt, mashed potatoes, scrambled eggs, smoothies (no straw). Skip anything hot, spicy, acidic, or carbonated. Avoid coffee for at least 48 to 72 hours because heat increases swelling and disrupts clotting. Don’t drink alcohol for at least a week. Don’t use a straw, since the suction can dislodge healing tissue.
After two weeks, you can start reintroducing more solid foods on the opposite side of your mouth. By three to four weeks, most people return to a fairly normal diet, though you’ll still want to keep crunchy or hard foods away from the grafted area.
Oral hygiene changes during recovery too. You won’t brush the graft area at all until your periodontist clears you. When you do resume, you’ll use an extra-soft toothbrush with gentle strokes. Avoid alcohol-based mouthwashes, which can burn or dry out the healing tissue. If you smoke, stopping for at least the first week is critical. Smoking delays healing and significantly raises the risk of complications.
Long-Term Success Rates
Gum grafts work well, but “success” depends on how it’s measured. A 20-year follow-up study of connective tissue grafts found that average root coverage started at 74% after one year and gradually decreased to 68% at 20 years. For milder recession cases (where the bone between teeth is intact), nearly half of patients still had complete root coverage two decades later.
Several factors influence whether results hold up over time. Teeth that had less than 2 millimeters of attached gum tissue were more likely to experience recession again. Smoking was associated with worse long-term outcomes. Teeth with existing wear notches on the root surface were also more prone to the gums shifting back down over the years. The best long-term results happen in cases where recession is caught early, before the bone between teeth has been lost.
Signs of a Failed Graft
Most grafts heal without problems, but knowing what to watch for helps you catch issues early. A large white patch of tissue pulling away from the tooth means the graft has lost its blood supply and isn’t surviving. Tissue that turns dark or black indicates tissue death and needs immediate attention. Other warning signs include persistent bleeding or swelling beyond the first few days, pus or foul odor (signs of infection), or visible gaps between the graft and surrounding gum tissue. If the graft appears to be shrinking and the root is becoming exposed again within weeks of surgery, that also suggests a problem.
Cost and Insurance
Gum grafts typically cost between $2,120 and $4,982 per area treated, depending on the type of graft, the number of teeth involved, and your geographic location. Many dental insurance plans cover at least part of the cost when the procedure is deemed medically necessary to stop ongoing recession. Grafts done purely for cosmetic reasons are less likely to be covered. Since untreated recession can lead to tooth loss, bone loss, and bacterial infection, most cases do qualify as medically necessary.
