How Long Do Dissolvable Stitches Last in the Mouth?

Dissolvable stitches in the mouth usually loosen and disappear within one to two weeks. Some types take two to three weeks—or a few weeks—to dissolve completely, so the timeline given by your surgeon takes priority.

For wisdom-tooth surgery, the British Association of Oral Surgeons says stitches usually dissolve by themselves in one to two weeks. Other postoperative instructions allow longer: University Hospitals Coventry and Warwickshire says mouth sutures can take up to two or three weeks, while UCLH says dissolution may take a few weeks.

What if a stitch becomes loose or falls out?

A stitch may become loose, leave a short thread against your tongue or fall out before it seems to have fully dissolved. This does not automatically mean something is wrong. Guy’s and St Thomas’ notes that stitches can loosen or be lost even immediately after dental surgery and that this does not normally cause a problem.

The gum may still have a dip or visible socket after the stitches are gone. Stitch dissolution and complete socket closure are separate parts of healing; see how a wisdom-tooth hole closes for the longer timeline.

Do not pull, cut or remove a dangling stitch yourself. If it repeatedly catches, hurts or remains beyond the timeline your surgeon gave you, call the treating office. They can identify the suture and decide whether it should be trimmed or removed.

Confirm whether your stitches dissolve

Not every mouth suture is dissolvable. Non-dissolving stitches must be removed at a follow-up appointment; Guy’s and St Thomas’ advises that these may be removed by the surgical team or a local dentist or doctor. Check your discharge instructions or ask the treating office if the suture type and follow-up plan are unclear.

Care for the area without disturbing it

Your procedure-specific instructions come first. Unless your clinician told you otherwise:

• Do not rinse, spit forcefully or touch the extraction area during the first 24 hours.
• After 24 hours, use the rinsing method your clinician recommended. A gentle salt-water rinse after extraction is commonly advised.
• Brush your other teeth and clean near the surgical site carefully without scrubbing or catching the threads.
• Avoid testing the stitches with your tongue or fingers.

These steps align with UCLH guidance to avoid rinsing, spitting or touching the area for 24 hours and Guy’s and St Thomas’ advice to brush gently around the treated area.

Stitches bring gum tissue together, but they do not guarantee that the protective blood clot remains in an extraction socket. That is why dry socket can still occur with stitches.

When to call the surgeon

Contact your surgeon or dentist promptly if:

• fresh bleeding persists despite the pressure method in your postoperative instructions
• pain starts getting worse rather than better after the first few days
• worsening pain comes with a foul taste or bad breath
• swelling spreads or worsens after it had started settling
• you develop a fever, feel generally unwell, or the skin over the jaw becomes hot, hard, red or tender
• a stitch is cutting into the tissue or remains well beyond the expected period

These pain and infection warning signs are described in the British Association of Oral Surgeons’ wisdom-teeth guidance. A stitch falling out without fresh bleeding, worsening pain or other concerning symptoms is usually not urgent. If you are uncertain, call the treating office rather than trying to repair or remove it at home.
