Gum and Bone Grafting Around Teeth
Regenerative periodontal procedures attempt to rebuild what the disease destroyed, rather than reshaping around it. Bone grafting places material into a bony defect around a tooth to act as a scaffold for new bone. Guided tissue regeneration adds a membrane over the graft to stop the faster-growing gum tissue from filling the space before bone can. Soft-tissue grafting — connective tissue or pedicle grafts — rebuilds gum over an exposed root.
What periodontal grafting and regeneration involves
Regenerative periodontal procedures attempt to rebuild what the disease destroyed, rather than reshaping around it. Bone grafting places material into a bony defect around a tooth to act as a scaffold for new bone. Guided tissue regeneration adds a membrane over the graft to stop the faster-growing gum tissue from filling the space before bone can. Soft-tissue grafting — connective tissue or pedicle grafts — rebuilds gum over an exposed root. The distinction from resective surgery matters. Osseous surgery accepts the bone loss and creates a maintainable shape at the new level. Regeneration tries to get some of the attachment back. Regeneration works best in specific defect shapes — narrow, contained, two- or three-walled defects — and poorly in wide flat ones.
When this treatment is used
Bone grafting and guided tissue regeneration are used for contained defects around teeth worth a substantial investment. Soft-tissue grafting is used for recession that is progressing, causing sensitivity, compromising appearance, or leaving too little tissue to be maintained.
Gum grafting, which patients ask about most
A connective tissue graft takes a thin layer of tissue from the palate and places it over an exposed root, usually under a flap raised from the adjacent gum. It covers the root, thickens the tissue, reduces sensitivity and improves appearance. Donor site alternatives exist — processed human or porcine tissue — which avoid a palatal wound at the cost of slightly less predictable results. Recovery involves the palate more than the graft site. Expect a week or so of discomfort where the tissue was taken, eating soft food, and a protective plate in some cases. Success rates for root coverage are good in suitable cases; the main determinant is how much tissue remains between the teeth adjacent to the recession. Not all recession needs grafting. Recession that is stable, not sensitive and not bothering the patient can reasonably be monitored with photographs and measurements. Progressive recession, or recession with no keratinised tissue left, is a different matter.
Coverage, which is the hard part
These are among the least reliably covered procedures in dentistry. Bone grafts and membranes around natural teeth are frequently excluded outright or paid at a fraction of the fee. Soft-tissue grafts fare somewhat better where recession is documented as progressive with a functional consequence, and worse where the documentation suggests appearance. A pre-treatment estimate is close to essential. So is a conversation about what the realistic alternative is — often extraction of the tooth in the case of bone defects, which changes the economics considerably.
Costs and insurance in summary
Typical fee range across the group: $0–$0 where a single band applies. Several codes here are priced individually and carry their own range on their own page. Priced per site as specialist surgery. Graft materials and membranes are frequently reported as separate line items.
Benefit category: Major periodontal, 0–50% on a typical plan. The least predictable area of periodontal coverage. Bone grafts and membranes around natural teeth are commonly excluded; soft-tissue grafts are sometimes paid with good documentation of a functional problem.
Common restrictions: Bone grafts and membranes around teeth are frequently excluded; Soft-tissue grafts need documented progression or functional consequence; Pre-authorisation and a pre-treatment estimate are strongly advisable; Grafts for cosmetic root coverage are excluded.
The codes this guide covers
Each of these describes a variant of the same procedure. Follow a code for its own fee range, its coverage notes and what distinguishes it from the rest of the group.
| Code | Variant | Typical fee |
|---|---|---|
| D4263 | Bone graft around a natural tooth (first site) | $500–$1,300 |
| D4264 | Bone graft around a natural tooth (additional site) | $300–$800 |
| D4266 | Guided tissue regeneration — resorbable membrane | $500–$1,400 |
| D4267 | Guided tissue regeneration — non-resorbable membrane | $700–$1,800 |
| D4273 | Connective tissue graft (gum graft) — most reported | $900–$2,200 |
Common questions
Do I need a gum graft for receding gums?
Not always. Recession that is stable, comfortable and not bothering you can be monitored with photographs and measurements. Grafting is indicated when it is progressing, causing sensitivity, or has left too little tissue to maintain.
Where does the tissue for a gum graft come from?
Usually a thin layer from the palate. Processed donor tissue is an alternative that avoids a palatal wound, with slightly less predictable results.
Is gum grafting covered by insurance?
Sometimes, where recession is documented as progressive with a functional consequence. Grafting purely to improve appearance is excluded.
Can bone lost to gum disease grow back?
Partially, in the right defect shape. Narrow contained defects respond reasonably well to grafting and membranes; wide flat bone loss does not regenerate predictably.
