What to Do If Dissolvable Stitches Are Sticking Out

A dissolvable stitch poking through your skin is almost always harmless and far more common than most people realize. Surgeons call this a “spitting suture,” and it happens when a buried stitch works its way toward the surface instead of quietly dissolving underneath. In most cases, the right move is gentle wound care and a bit of patience, though there are specific signs that warrant a call to your doctor. What matters most is knowing the difference between a minor annoyance and a developing problem.

Why Dissolvable Stitches Work Their Way Out

Dissolvable (absorbable) stitches are designed to be placed beneath the skin surface, where they hold tissue together while healing progresses. Your body breaks them down through an inflammatory process over weeks to months, depending on the material. Sometimes, though, that inflammatory response pushes the stitch upward instead of dissolving it in place. The stitch migrates through the tissue layers until a small loop, knot, or tail pokes through the skin. This is a spitting suture, and it is one of the most common complications after any surgery that uses buried stitches to close a wound.¹

Several things make spitting more likely. Stitches placed close to the surface have less tissue to travel through. Areas with thin skin or a lot of movement, like the chest, shoulders, and extremities, are especially prone. Your body’s immune response also plays a role: some people mount a stronger inflammatory reaction to the suture material, which accelerates the push toward the surface. And certain suture materials provoke more tissue reaction than others, a point worth understanding if you keep having this problem.

What You Can Safely Do at Home

If you notice a small thread or loop sticking out of your incision, here is what you can do without panicking:

Leave it alone if possible: A stitch that is simply visible or barely protruding often resolves on its own. The body continues to dissolve the material, and within a few days to a couple of weeks, the exposed portion may soften and fall off or retract back beneath the skin.
Keep the area clean: Gently wash the area with mild soap and water. Pat dry. You do not need special antiseptic solutions unless your surgeon told you to use one.
Do not pull on it: Tugging on a stitch that is still anchored beneath the surface can reopen part of the wound or damage healing tissue. Even if the exposed thread looks like it would come out easily, the buried portion may still be holding tissue layers together.
Trim only what is clearly loose: If a long tail of suture is dangling free and catching on clothing, you can carefully trim it with clean, sharp scissors right at the skin surface. Sterilize the scissors with rubbing alcohol first. Do not cut below the skin line, and do not dig around the area.
Cover it lightly: A simple adhesive bandage over the spot prevents the exposed thread from snagging on fabric and keeps the area reasonably clean.

Written discharge instructions from emergency departments and surgical clinics typically advise patients to watch for loose stitches and to keep follow-up appointments for this reason.² The emphasis is always on monitoring rather than self-removal. If your surgeon’s office gave you specific aftercare instructions that differ from the general advice above, follow those instead.

When You Should Call Your Doctor

Most spitting sutures are a nuisance, not a danger. But a stitch poking through the skin creates a tiny channel from the outside world into your wound, and that channel can become an entry point for bacteria. The complication that dermatologic surgeons worry about most with spitting sutures is surgical-site infection and abscess.¹ Contact your doctor if you notice any of the following:

Spreading redness: Some pinkness right around the stitch site is normal. Redness that expands outward from the incision, especially with streaking, suggests infection is spreading.
Increasing pain: Mild tenderness near a spitting stitch is expected. Pain that gets worse over a couple of days, or that throbs, is a warning sign.
Pus or cloudy drainage: A small amount of clear or slightly yellow fluid can be normal wound drainage. Thick, opaque, foul-smelling discharge is not.
Fever: Any temperature above about 100.4°F (38°C) in the days after surgery deserves a call.
A growing lump: A firm, persistent bump forming around the stitch site may indicate a suture granuloma, which sometimes needs professional treatment.
Wound separation: If the edges of your incision are pulling apart near the exposed stitch, your doctor needs to assess whether the closure is holding.

When in doubt, send a photo to your surgeon’s office. Many practices now handle these questions through patient portals or telehealth visits, and a quick image often tells the surgeon everything they need to know without you making a trip in.

What Happens If You Go In

If you do see your doctor about a protruding stitch, the visit is usually brief and straightforward. The most common intervention is simply removing the offending suture. By the time a buried stitch has migrated to the surface, the deeper tissue it was holding together has often healed enough to stay intact without it. Your doctor can clip and pull the stitch out with forceps in a few seconds, typically without any local anesthetic because the surrounding tissue has lost sensation in the area or the stitch is superficial enough that removal feels like a slight tug.

If there is a small abscess forming around the stitch, the doctor may need to open it slightly, drain it, and possibly prescribe a short course of antibiotics. This is uncommon but not rare, and it heals well once the foreign material is removed and the pocket is cleaned. In cases where multiple stitches are spitting along a long incision, the surgeon may remove several at once and reinforce the closure with adhesive strips if needed.

Dissolvable Stitches in Specific Locations

Where your stitches are located changes the advice somewhat, because different body sites heal at different rates and face different stresses.

Inside the mouth, dissolvable stitches after wisdom tooth extraction or other oral surgery commonly loosen within a week. The warm, wet, enzyme-rich environment of saliva speeds up the breakdown of suture material. A stitch dangling from your gum line after a tooth extraction is rarely a problem. You can usually leave it alone; if it is bothering you or making you gag, your oral surgeon can snip it at your next check-in. Rinsing gently with warm salt water helps keep the site clean without disturbing the stitch mechanically.

After a cesarean section, spitting sutures on the abdomen are common because the incision is long, under tension from normal movement, and closed in multiple layers. The abdominal area also has varying skin thickness across the incision. If you see a stitch poking through your C-section scar, the same general rules apply: keep it clean, do not pull, and contact your OB if you see signs of infection. Because the incision is in a skin fold that can trap moisture, keeping the area dry is especially worthwhile.

On the face, cosmetic concerns matter more. A spitting stitch on a facial incision can leave a small scar or pockmark if it sits there for weeks causing chronic irritation. Facial skin also tends to be thinner, so buried sutures do not have far to travel before they surface. If you notice a stitch poking through a facial incision, it is worth contacting your surgeon sooner rather than later. Early removal of a spitting facial suture gives you the best chance at a clean cosmetic result.

The Timeline Problem

One of the most frustrating things about dissolvable stitches is how unpredictable their absorption can be. The label says “dissolvable,” so patients reasonably expect them to just disappear. In reality, absorption time varies dramatically based on the suture material, the location in the body, and individual biology. Some fast-absorbing sutures break down in about ten days. Others can take several months, and fragments occasionally persist much longer than expected.

Rapidly absorbing synthetic sutures were developed in part to reduce the need for suture removal while still offering wound support comparable to standard synthetics.³ Faster-dissolving materials are designed to minimize the window during which a stitch might cause irritation. But even with these newer materials, the rate of dissolution depends on local blood supply, tissue pH, and how much mechanical stress the site experiences. A stitch on a joint that moves constantly may irritate tissue and provoke a stronger inflammatory response, while the same material in a low-movement area might quietly dissolve on schedule.

The practical takeaway: if your dissolvable stitches have not dissolved by the time you expected, that alone is not cause for alarm. But if a stitch is visibly sticking out and has not budged in two to three weeks, and especially if the area around it is getting irritated, a quick visit to have it removed is reasonable.

Suture Granulomas

Sometimes the body’s reaction to a buried stitch goes beyond simple inflammation and forms a granuloma, a firm, rounded bump of immune cells that walls off the foreign material. Suture granulomas represent a foreign body reaction and can occur with both absorbable and non-absorbable suture materials.⁴ They tend to show up as a painless or mildly tender lump near the incision, sometimes weeks or months after surgery, and they can be mistaken for a cyst, an abscess, or even a tumor.

Most suture granulomas are small and eventually resolve on their own once the suture material finishes dissolving. But if the suture remnant persists or the granuloma is large enough to be bothersome, a doctor may excise it. In a study of canthal (inner eyelid) surgeries, the overall granuloma rate was about 2.4%, and the type of suture material made a substantial difference: non-absorbable braided sutures were roughly 23 times more likely to cause granulomas than absorbable braided sutures.⁵ That finding lines up with broader evidence that absorbable materials, because they eventually disappear, give the immune system less reason to mount a prolonged foreign body response.

If you develop a firm lump along your incision line weeks after surgery, mention it to your surgeon. It is almost certainly benign, but distinguishing a granuloma from an infection or other complication usually requires a clinical exam, and occasionally imaging or a biopsy if the lump is in an unusual location.

Why Suture Material Matters

Not all dissolvable stitches are created equal, and if you have had repeated problems with spitting sutures or granulomas, the type of material used may be part of the explanation. Sutures come in two basic structural categories: monofilament (a single smooth strand) and multifilament or braided (multiple strands woven together). Research on tissue reactions in oral surgery has found that multifilament materials like silk, polyester, and cotton provoke a significantly stronger inflammatory response compared to monofilament materials like nylon and surgical gut.⁶

The reason is partly mechanical: braided sutures have a rougher surface with tiny crevices that can harbor bacteria and irritate tissue as they pass through it. Monofilament sutures slide through tissue more smoothly and offer fewer hiding places for microorganisms. For the patient, this does not mean one type is always better. Braided sutures hold knots more securely and are easier for surgeons to handle, which is why they remain widely used. But if you are someone who repeatedly develops spitting sutures or granulomas, it is worth asking your surgeon whether a monofilament alternative could be used for your next procedure.

Modern synthetic absorbable sutures, such as polyglactin and poliglecaprone, have largely replaced older materials like catgut in most surgical settings. Synthetic sutures tend to cause less short-term pain and require resuturing less often than catgut.³ The shift toward synthetics has reduced but not eliminated the problem of spitting and granuloma formation. No suture material is invisible to the immune system, but the newer synthetics provoke less drama on average.

What Surgeons Do to Prevent Spitting

Surgeons have developed specific techniques to reduce the odds of a buried stitch working its way out. The depth at which the suture is placed matters enormously. A stitch buried deep in the dermis has more tissue between it and the surface, giving the body more time to dissolve it before it can migrate upward. Knot placement also matters: if the knot faces the surface rather than the deeper tissue, it is more likely to poke through.

Specialized techniques like the lateral pulley buried dermal suture were designed partly to address this problem. This method places the knot and the main loop of suture deep under the skin, reducing tension on the wound edges and compressing less tissue near the surface.⁷ The result is a closure that distributes mechanical stress across a wider area, which means each individual stitch is under less pressure and less likely to be pushed outward by the body’s inflammatory response. Techniques like this are especially useful for wounds under high tension, such as those on the back, shoulders, or chest where the skin constantly pulls against the closure.

None of this guarantees zero spitting. Even with optimal technique and the best available materials, some patients will still have stitches work their way to the surface. The variables that affect it, including individual inflammatory response, wound tension, body site, and movement during healing, are only partially under the surgeon’s control. But if you have a history of problematic wound healing or suture reactions, sharing that information before your next procedure gives your surgeon the chance to choose materials and techniques that reduce the odds.

Stitches Left in Too Long

A related concern that sometimes gets confused with the spitting-stitch problem: what happens if dissolvable stitches do not dissolve and just stay put? For truly absorbable sutures, the material will eventually break down. The process can be slower than expected, but it does happen. However, if non-absorbable stitches were used (which happens more often than patients realize, sometimes as deeper anchor sutures in a wound that also has dissolvable ones closer to the surface), those will not dissolve at all and do need to be removed.

Discharge guidance from emergency departments emphasizes that if sutures or staples are in place, keeping the removal appointment is important because stitches left in too long can cause permanent marks on the skin.² This applies mainly to non-absorbable surface sutures, but the principle extends to any stitch that is sitting at the skin surface for an extended period. Even a dissolvable stitch that has partially extruded and is now essentially sitting on top of the skin can cause small scars or track marks if left for weeks. If you are unsure whether your stitches are absorbable or not, your surgeon’s office can tell you from the operative notes, and it is always a fair question to ask at the time of surgery.

The broader lesson is that “dissolvable” does not always mean “no follow-up needed.” Your body handles the breakdown on its own schedule, and sometimes a stitch needs a little human help to exit gracefully. Keeping your follow-up appointments and watching the incision site for changes are the two most reliable things you can do to catch small issues before they become bigger ones.
