They start dissolving within about 5 to 10 days and disappear over the weeks after that.
NHS guidance on absorbable sutures explains they are made of material the body absorbs naturally, so they never need taking out. Timing varies by design: surface stitches in fast-healing areas go quickly, while buried stitches are made to hold tension for weeks before the body breaks them down, so a firm ridge under the skin can be normal for a while. Loose ends and itchy knots are common and can be trimmed by a nurse. MedlinePlus is firm on one rule: do not pull at stitches or try to remove them yourself.
What to do
Common questions
How long do dissolvable stitches last?
Most dissolvable stitches start to absorb within about 5 to 10 days and soften away over the weeks that follow, no removal appointment needed. NHS guidance on absorbable sutures says they are made of material the body absorbs naturally, typically starting 5 to 10 days after they are put in. The exact lifespan depends on the material and where they are: stitches in the mouth can vanish within days, while deeper stitches under the skin are built to hold for weeks before dissolving, which is why you sometimes feel a firm ridge under a healed scar. Ends poking out and a knot catching on clothing are common annoyances; a practice nurse can trim a bothersome knot easily. What you should not do is pull, cut, or pick at them yourself. MedlinePlus warns not to pull at stitches or try to remove them on your own. If the wound becomes inflamed, increasingly painful, or leaks discharge, contact your surgery team rather than waiting for the stitches to disappear.
