What Should I Do About the Stitches in My Mouth?
Some oral stitches dissolve and others need removal. Learn how to protect them, handle a loose thread and confirm when the dental team should check it.

A thread against your tongue can be surprisingly noticeable after mouth surgery. Before trying to work out whether it should still be there, check which kind of stitch was used. Dissolving, or resorbable, stitches break down over time. Other stitches need a planned removal visit. The procedure name alone does not tell you which kind you have.[1][2]
Use your own expected timetable
Cambridge University Hospitals describes many oral dissolving stitches lasting about ten days to two weeks. Different materials and procedures can have different timelines, so ask the treating team when yours should disappear and when a remaining thread needs review. A removal appointment for non-dissolving stitches still matters even if the wound feels comfortable.[1][2]
Write down the answer while it is easy to ask. 'These dissolve; call if they remain beyond the time we discussed' is a different plan from 'Come back to have these removed.' If you cannot remember which you were told, contact the clinic rather than deciding from the colour of the thread.
Leave the thread alone
Do not fiddle with stitches using your tongue or fingers. Do not pull or cut a loose end yourself. Follow the cleaning instructions for the operation, which may differ between an extraction, gum surgery and a biopsy. Avoid borrowing a mouthwash schedule from a different procedure simply because both involved stitches.[4]
If a thread catches on food or feels sharp, explain that to the clinic. They can decide whether it needs checking or trimming professionally. You do not have to tolerate an irritating end until an arbitrary two-week deadline, and removing it yourself is not the only alternative.
A loose stitch is not the whole story
A stitch can loosen or come away early without necessarily causing a problem. What matters is the condition of the wound and the symptoms with it. Contact the team if the edges appear to separate, bleeding persists, pain or swelling is increasing, or you are unsure what has happened. Seek urgent help for heavy bleeding or difficulty breathing or swallowing.[3]
When you call, give the date and type of surgery, whether the stitch fell out or is still attached, and what changed afterward. Avoid repeatedly pulling your cheek aside to obtain a better photograph. The team can tell you whether a picture would help or whether they need to examine the site.
