Is my gum graft falling off?
Cited to 4 sources. Reviewed 2026-08-25.
Most gum grafts that look like they are falling off are not. What people usually see is the white fibrin film sloughing off in week two, a loose suture end, or a piece of the dressing coming away. Genuine graft failure looks different: a firm patch of white tissue that has come off the tooth, meaning it lost its blood supply. If you see that, or the graft has visibly moved, call your periodontist rather than waiting.
- Most common false alarm
- White fibrin film sloughing, days 7 to 14
- Real failure sign
- White tissue detached from the tooth
- Second real sign
- Graft has visibly shifted or slid
- What to do
- Call the office, do not touch it
The four things people mistake for a failing graft
Almost every panicked call in the first two weeks turns out to be one of these.
- The white film peeling off. This is fibrin, the mouth's version of a scab, and it comes away in patches around days 7 to 14. It is on top of the graft, not the graft itself.
- A loose suture end. Sutures work loose or dissolve at different rates. A dangling thread does not mean the graft is unsecured, though it is worth mentioning at your follow up.
- Surgical dressing coming away. If a periodontal dressing or putty was placed, chunks of it detach as it ages. It looks alarming and is not tissue.
- The graft looking pale, raised or a different color from the gum next to it. Grafted tissue commonly stays lighter and thicker looking for weeks before it blends.
What actual graft failure looks like
Graft failure means the transplanted tissue did not establish a blood supply and has died. Cleveland Clinic describes the sign to watch for as a large patch of white tissue that has come off of your tooth.
The key word is off. A film sitting on the surface is normal. A firm, sheet like piece of tissue that has separated from the tooth and gum, leaving the root exposed again underneath, is not.
Partial failure is more common than total failure. You may get coverage over part of the root and lose it over another part, often at the very tip where the blood supply from the surrounding tissue has furthest to travel. That can still be a workable result, and it is your periodontist's call, not something you can judge from a mirror at week one.
| What you see | Likely explanation | Action |
|---|---|---|
| Soft white film flaking away, pink underneath | Normal fibrin sloughing | Leave it alone |
| Thread hanging from the site | Loose or dissolving suture | Mention at follow up |
| Grainy putty like material breaking off | Surgical dressing | Mention at follow up |
| Firm white sheet lifted off the tooth, root visible | Possible graft failure | Call the office now |
| Graft visibly lower or shifted from where it was placed | Graft displacement | Call the office now |
| Site newly bleeding, painful and swollen after day 4 | Possible infection or trauma | Call the office now |
What causes a graft to actually fail
A graft over an exposed root has no blood supply from the root itself. It survives on vessels growing in from the tissue at its edges, which takes days to establish. Anything that interrupts that in the first week is what puts a graft at risk.
Mechanical disturbance is the leading cause: brushing or flossing the site, pulling the lip out to inspect it repeatedly, chewing on that side, forceful rinsing, or strenuous exercise and heavy lifting in the first week. Cleveland Clinic specifically warns that brushing or flossing directly on the graft can damage it and lead to failure.
Smoking is the biggest systemic risk. Root coverage studies consistently find worse outcomes in smokers, and the National Institute of Dental and Craniofacial Research notes that tobacco delays healing.
Infection is much less common but possible, and is one reason many periodontists prescribe an antimicrobial rinse instead of brushing during early healing.
If you think it has failed
Call the office and describe what you see, or send a photo if they accept them. Do not pull at it, do not try to reposition it, and do not brush it to clean it up.
If a graft does fail, it is usually not the end of the road. Periodontists can often regraft the area once the tissue has settled, and knowing why the first one failed, whether that was smoking, trauma or a difficult defect, changes how the second attempt is planned. Getting seen early gives you more options than waiting it out.
Call your dentist or oral surgeon if
- A firm patch of white tissue that has separated from the tooth, with the root exposed underneath
- The graft has visibly moved, slid down, or looks smaller than it did
- Bleeding that restarts and will not stop with 15 to 20 minutes of steady gauze pressure
- Pus, a persistent bad taste, or redness spreading beyond the site
- Fever above 101 F
- Pain that is worsening after day 4 instead of improving
Related questions
Can a gum graft fall off?
Displacement is rare but possible, usually from trauma to the site in the first days. Far more often what looks like the graft falling off is the fibrin film or a dressing coming away. Either way it is worth a call.
What does a failed gum graft look like?
A large patch of white tissue that has come off the tooth, rather than a film sitting on the surface. The exposed root is typically visible again underneath.
How soon would a graft fail?
Failure from lack of blood supply generally shows itself in the first one to two weeks, which is exactly when the normal white fibrin stage also occurs. That overlap is why the two get confused.
Can a failed gum graft be redone?
Often yes. Periodontists commonly regraft once the tissue has settled. Getting assessed early matters, so call rather than waiting for your scheduled visit.

A healing gum graft usually turns white, gray or yellowish within the first few days, and that is normal. It is a fibrin layer over the wound, not dead or infected tissue. That film sloughs off over roughly one to two weeks and pink tissue appears underneath. The graft often stays pale, raised or slightly patchy for weeks before it blends. The appearance that actually signals trouble is a sheet of white tissue that has lifted away from the tooth.
You cannot fairly judge a gum graft at two weeks. At that point success just means the tissue is attached, not detached, and starting to turn pink. By six weeks you should see thicker tissue over the root and less exposed root than before surgery. By three months color and contour should be blending and sensitivity should be down. The clearest sign it did not work is a firm patch of white tissue that has come off the tooth.
The first week comes down to leaving the graft completely alone. Do not brush or floss at the site, do not rinse forcefully, do not chew on that side, and do not pull your lip or cheek out to inspect it. Eat soft and cool, skip exercise and heavy lifting for at least the full week, and use the rinse your periodontist prescribed. If you have a palatal stent, keep it in as instructed. Everything else in your mouth gets normal care.
You should not smoke after a gum graft, and this is one of the few aftercare rules with hard outcome data behind it. A prospective clinical study found non smokers healed with 98.3 percent root coverage versus 82.3 percent in smokers at six months, and a systematic review of root coverage procedures found non smokers gained significantly more. Tobacco also delays wound healing generally. The first two weeks matter most, but quitting entirely gives the graft its best chance.
