Stitches you were told to have removed are made of thread your body can’t break down, so they stay until someone takes them out. Leaving them a few extra days is rarely an emergency, but the longer they stay, the more your skin treats them as a permanent part of the wound. The real costs of waiting are mostly a worse-looking scar and a higher chance of a lingering infection, not sudden danger.
Why Some Stitches Have To Be Removed
Dissolving stitches are broken down by the body, many by water slowly splitting the thread, until nothing remains.1Dolphin Sutures. Absorbable vs Non-Absorbable Sutures: How They Differ and When Each Is Used Non-absorbable (non-dissolving) stitches resist that process and stay for as long as they are left in.2Dolphin Sutures. Absorbable vs Non-Absorbable Sutures: How They Differ and When Each Is Used They are chosen when a wound needs firm, lasting support, such as skin under tension.3Pipeline Medical. 5 Critical Differences: Absorbable Vs Non-Absorbable Sutures So when your clinician used them, they planned a removal visit.
Checking which kind you have is easier than it sounds. Your discharge papers often say, and a quick call to the clinic can confirm the stitch type and the planned removal date. Thread color is a clue, not proof: blue, black, or stiff shiny thread sitting on top of the skin is often non-dissolving, but some dissolving thread is dyed too, so color alone shouldn’t decide it. If someone told you to come back to have them removed, treat them as non-dissolving however they look. And if you can’t find out, assume visible thread on the skin needs a clinician’s check rather than waiting for it to vanish.
Non-dissolving thread is a foreign material, so the body never fully accepts it. Thread left in tissue keeps a low level of inflammation going where it touches the body.4PubMed Central. Imaging of Foreign Body Reactions to Non-absorbable Sutures in Achilles Tendon Repair: Radiologic and Histopathologic Correlation in Two Cases Over time the body builds scar-like tissue and eventually a tough capsule around it.5PubMed Central. Imaging of Foreign Body Reactions to Non-absorbable Sutures in Achilles Tendon Repair: Radiologic and Histopathologic Correlation in Two Cases
The stitches only need to hold the wound edges together while new tissue builds strength. That’s why the removal date depends on how fast that body area typically gains strength, not on how the wound looks. The surface can seem fully closed well before it is.
Skin Grows Over the Stitches and Leaves Marks
It’s common for skin to start covering stitches left in past their date.6HealthTap. My skin is growing over my stitches, they are prolene(non dissolving). should i be worried? Removal can then be harder, and the clinician may need to numb the area first.7HealthTap. My skin is growing over my stitches, they are prolene(non dissolving). should i be worried? On its own, this is not usually cause for worry.8HealthTap. My skin is growing over my stitches, they are prolene(non dissolving). should i be worried?
What overdue stitches look like: the thread sits in tiny pits, with the skin edge rolling slightly over it so parts are hard to see. The skin right around each stitch may look pink, puckered, or slightly raised. That is often just the skin reacting to thread, though it’s worth telling apart from the spreading redness of infection. The stitches may feel tight, tugging, or itchy, especially as early swelling goes down and the skin settles around the thread.
The lasting cost is stitch marks. Where each stitch passes through the skin, the hole fills with skin cells and scars if the thread is left too long.9Dr. George Sanders | Excellence in Plastic Surgery in the Los Angeles Area. What’s Up With Stitches? You can end up with a “railroad track” scar: a central line with rows of dots on either side.10Dr. George Sanders | Excellence in Plastic Surgery in the Los Angeles Area. What’s Up With Stitches? These stitch marks are permanent,11Health Research Authority. Timing of Suture Removal to Reduce Scarring in Skin Surgery and the risk rises the longer stitches stay in.12Health Research Authority. Timing of Suture Removal to Reduce Scarring in Skin Surgery In skin surgery, people whose stitches came out at 7 days rated their scars better than those at 10 days, with no more wounds reopening.13Health Research Authority. Timing of Suture Removal to Reduce Scarring in Skin Surgery
Tension makes this worse, so stitches pulled tight, or sitting on a stretchy area, tend to leave clearer marks than those on calm skin. The marks come from time spent in the skin, not from the stitching itself, so a well-placed wound can still be marked if removal is delayed.
Marks fade somewhat over months but usually don’t vanish. Timing matters most on the face and other visible areas. If the marks bother you once the skin has healed, ask about scar treatment options.
Old Stitches Can Hold On to Infection
Stitch thread gives germs a surface to cling to. Germs can form a sticky protective layer on it.14PubMed Central. Microbiology of explanted suture segments from infected and noninfected surgical patients In stitches taken from infected wounds, this layer was found every time, and on two-thirds of stitches from wounds that weren’t infected.15PubMed Central. Microbiology of explanted suture segments from infected and noninfected surgical patients Braided thread holds far more of this germ layer than smooth single-strand thread in lab tests.16PubMed Central. Gardnerella biofilm formation in vitro is facilitated by braided sutures: implications for cervical cerclage
The layer shields germs from the immune system and from many antibiotics, so the same germs can be much harder to clear on thread than when they float free. Washing the skin cleans the surface but can’t reach germs living in the thread tunnel under the skin.
Even after a wound is washed out, any remaining thread can still harbor bacteria.17PubMed Central. Does Suture Type Influence Bacterial Retention and Biofilm Formation After Irrigation in a Mouse Model? In one reported chronic wound infection, removing the stitches is what finally cleared it.18PubMed Central. Chronic Surgical Site Infection Due to Suture-Associated Polymicrobial Biofilm
Redness that spreads outward from the stitches over a day or two, along with growing warmth, is more worrying than a thin pink rim hugging the wound. Growing swelling, pus, or a bad smell suggests germs are active and not just normal healing. Pain that gets worse after the first few days is a warning too, since a healing wound should hurt less over time. Fever, chills, or red streaks running from the wound need same-day medical care, because they suggest the infection is spreading.
A clinician may remove some or all of the stitches early, because taking out the thread takes away the surface the germs are clinging to. If pus has collected, they may open the wound slightly to drain and clean it. Antibiotics may be added, though they may work less well while infected thread is still in place. If you suspect infection, don’t wait for the original removal date.

Timing also depends on the thread used and how you heal.26Suture Manufacturer in India. A Complete Guide on When to Remove Sutures Safely If your clinician gave you a date that differs from these, follow theirs.
The face has a rich blood supply and heals quickly, and scars there are the most visible, so stitches come out early to avoid dots. Hands, feet, and joints stretch and bend constantly, so the wound needs longer support before it can hold on its own. Legs and lower areas often heal more slowly, which is part of why they sit in the longer range.
Should You Take Them Out Yourself
Removal is usually simple, but you shouldn’t do it yourself.27CVS MinuteClinic. Stitch and staple removal The clinician first checks that the wound has healed enough to hold without stitches.28CVS MinuteClinic. Stitch and staple removal They also look for infection, bleeding, or other problems needing care.29CVS MinuteClinic. Stitch and staple removal
Your surgeon’s office, a family doctor, urgent care, or a walk-in clinic can generally remove stitches, so you don’t need to return to the original place if that’s hard. The visit usually takes minutes: the clinician snips each stitch and pulls the thread out. They may put thin tape strips across the wound afterward for extra support while it finishes strengthening. Tell them how many days overdue you are, and mention any redness, pain, or discharge so they can check for infection.
Doing it yourself carries real risks. If the wound isn’t ready, pulling stitches can let it reopen, which can mean new stitches or a worse scar. Household scissors and tweezers aren’t sterile and can bring germs into a wound that is still healing. Thread that is partly buried can snap, leaving fragments in the skin that are harder to remove later. Pets licking or pulling at stitches can yank them out early or introduce germs, so keep the area covered and out of reach.
Dissolving Stitches and Stitches Inside the Body
A buried dissolving stitch can be pushed to the surface along the scar, which is called “spitting.”30Cutis. An Algorithm for Managing Spitting Sutures It often brings redness, swelling, discharge, and a poking feeling, and can lead to infection.31Cutis. An Algorithm for Managing Spitting Sutures In skin surgery this happened with about 3 in 100 stitches of one common type and about 11 in 100 of another.32PubMed. Comparison of poliglecaprone-25 and polyglactin-910 in cutaneous surgery It usually happens during the weeks of healing, as the body pushes the stitch outward while the thread is still breaking down, and it doesn’t mean the surgery failed.
A stitch poking through the skin can be tempting to pull, but yanking it can tear tissue or leave part of it behind. A clinician can trim or remove the exposed end cleanly, which is a quick fix. Meanwhile, keep the area clean and dry and avoid picking at it. Get it checked sooner if it becomes red, swollen, or starts draining.
Stitches inside the mouth are usually the dissolving kind. They usually loosen and fall out in 3 to 14 days, with fragments lasting up to a month.33Acibadem Hospitals Group. Dissolvable Stitches in Mouth: How Long They Last & Care You generally don’t need a removal visit, and lingering fragments aren’t a problem by themselves. Contact your clinician if you have increasing pain, swelling, or a bad taste, as these can signal infection.
Permanent stitches inside the body can, rarely, cause an abscess long after surgery, especially braided silk.34PubMed.
