Gum Grafting: Types, Procedure and Recovery

Gum grafting — known clinically as a gingival graft or soft-tissue graft — is a periodontal surgical procedure that adds tissue to the gum line where it has thinned or pulled away from the tooth. The goal is to rebuild a band of healthy, attached gum: to cover an exposed root, to thicken gum that has become too thin, or to protect the tooth from further loss of supporting tissue.

The most common reason a graft is recommended is gum recession, where the gum margin migrates down the tooth and exposes part of the root. Recession can follow periodontal disease, aggressive brushing, a naturally thin gum type, or grinding habits such as bruxism that load teeth heavily.

As the root becomes exposed, patients often notice the tooth looking longer, sensitive teeth when eating or drinking, and a higher risk of root-surface tooth decay because the exposed root has no protective enamel.

It is worth being clear about what grafting is and is not. A graft addresses the soft tissue around a tooth; it does not treat the colour or shape of the tooth itself, which is the territory of veneers or dental crowns.

Where bone rather than gum is deficient, the relevant procedure is a bone graft, which is a different operation. Gum grafting is a recognised, well-studied technique, but it is surgery, and whether it is the right call is a clinical decision made by a periodontist after examining the specific tooth and gum type.

There is no single "gum graft." The term covers a family of techniques that differ mainly in where the replacement tissue comes from and how it is positioned. The right choice depends on the goal — root coverage versus thickening thin gum — the amount of tissue available, and the periodontist's judgement of which technique is most predictable for that tooth.

The table below sets out the main types patients are likely to hear discussed.

Graft type

Where tissue comes from

Main use

Connective tissue graft (CTG)

A layer taken from beneath the surface of the palate (roof of the mouth), leaving the surface layer in place

Covering exposed roots; widely regarded in the literature as the most predictable option for root coverage

Free gingival graft (FGG)

A full-thickness piece taken directly from the surface of the palate

Thickening a thin band of gum and increasing the zone of attached tissue, rather than maximum root coverage

Pedicle (lateral) graft

Gum borrowed from immediately next to the recession, kept partly attached and rotated over the defect

Covering a root when there is plenty of healthy gum directly beside the affected tooth, preserving its own blood supply

Donor / substitute tissue graft

Processed donor tissue (allograft) or a collagen matrix derived from animal tissue (xenogeneic matrix) instead of the patient's own palate

Avoiding a second surgical site on the palate; used when own-tissue harvest is undesirable or insufficient

The connective tissue graft is the technique most often described in periodontal research as the reference standard for covering exposed roots, frequently combined with a flap that is advanced over it. Free gingival grafts are more about reinforcing thin or fragile gum than achieving full coverage. Pedicle grafts rely on having a generous donor zone right next to the problem area.

Donor or substitute materials — processed human donor tissue or animal-derived collagen matrices — are increasingly used to avoid taking tissue from the patient's own palate, though the evidence on whether they match own-tissue grafts for coverage is still evolving. None of these is universally "best"; each suits a different defect.

Gum grafting is usually a single-visit outpatient procedure carried out under local anaesthesia, so the patient is awake but the area is fully numbed. For anxious patients or larger cases, sedation may be discussed. The treatment begins with a periodontal assessment of how much recession is present, how thick the surrounding gum is, and the health of the underlying tooth and root surface.

The technical steps depend on the graft type chosen. For a connective tissue graft, the periodontist gently lifts a small flap of gum at the recession site, harvests a thin layer of tissue from beneath the surface of the palate, places it over the exposed root, and secures it with fine sutures, often drawing the existing gum over the top.

For a free gingival graft, a surface piece of palatal tissue is positioned and sutured to widen the band of attached gum. For a pedicle graft, adjacent gum is partially freed and slid across the defect while keeping its own blood supply intact. Where donor or substitute material is used, it takes the place of the palatal harvest, removing the need for a second surgical site.

The procedure typically takes from around forty-five minutes to a couple of hours depending on how many teeth are involved and the technique. A dressing or protective layer may be placed over the site. The periodontist's experience and accurate case selection — choosing the right graft for the defect — matter more to the outcome than any single brand of material.

As with any oral surgery there are risks, including bleeding, infection, partial graft loss and incomplete coverage, which the surgeon should explain and document in advance.

Recovery from gum grafting is generally manageable but does require care, particularly at the donor site if tissue was taken from the palate. Most patients describe more discomfort from the roof of the mouth than from the graft site itself; using processed donor or substitute material avoids this second wound entirely, which is one reason it is sometimes preferred.

In the first one to two weeks, the priority is protecting the newly placed tissue while it establishes a blood supply. Periodontists commonly advise a soft, cool diet, avoiding chewing directly on the treated area, and steering clear of pulling the lip or cheek to inspect the site, which can disturb the sutures.

Brushing the grafted area is usually paused and replaced with a prescribed antimicrobial rinse for a defined period, with normal cleaning reintroduced gradually on the surgeon's instruction. Some swelling, minor bleeding and colour change in the graft during early healing are expected as it integrates.

Initial soft-tissue healing typically settles over a few weeks, while full maturation and final gum contour continue over several months. Outcomes vary between patients: many grafts achieve substantial or complete root coverage, but the degree of coverage depends on the defect, the technique and individual healing, and no clinic can responsibly promise a specific percentage in advance.

Follow-up appointments check that the graft has taken and that suture removal, where needed, happens at the right time. Long term, protecting the result means addressing the original cause — gentle brushing technique, treating any underlying gum disease, and managing grinding — so the recession does not simply return.

Gum grafting is considered for patients with noticeable gum recession that is causing root sensitivity, root-surface decay risk, progressive loss of attached gum, or aesthetic concern from exposed roots — and for people with a naturally thin gum type that needs reinforcing before or alongside other treatment.

It is not a first response to every minor recession; mild, stable cases are often monitored rather than operated on. Candidacy is confirmed by a periodontist after examining the gum type, the extent of recession and the health of the supporting tissues, ideally once any active periodontal disease has been brought under control first.

There are also situations where a graft is not the answer. If teeth are already failing or missing, the conversation shifts toward replacement options such as dental implants, and where recession has occurred around an existing implant — a sign of peri-implantitis — management differs from grafting around a natural tooth.

A responsible plan rules these in or out before recommending surgery.

On cost, gum grafting is usually priced per site or per tooth rather than as a flat fee, because a single recession costs less to treat than several teeth grafted together. As an indicative guide, periodontal grafting in Turkey is typically a fraction of the equivalent fee in the USA, UK or Germany, but the only meaningful figure is a written, itemised quote produced after a clinical examination.

A complete quote should make clear how many sites are planned, which graft technique and material are proposed, whether donor or substitute tissue is included, and what follow-up and suture removal are covered. All figures are indicative ranges and vary by case.
