Post-Wisdom Tooth Extraction: What to Do About Remaining Stitches? - Dentistry

Share to:

The wisdom teeth have been extracted and the stitches have been removed?


I would like to inquire about the black thread I noticed the day after my wisdom tooth extraction and suture removal.
The doctor did not mention that I needed to return for further removal, but there is still a piece on the gum of my second molar.
Will this have any impact?

Hello: If there are remaining sutures that have not been removed, it is essential to return for a follow-up appointment to have them taken out as soon as possible, otherwise, it may lead to inflammation.

More Info


After a wisdom tooth extraction, it is common to have stitches (sutures) placed to help the healing process. These stitches can be either dissolvable or non-dissolvable. If you notice a black thread-like material on your gums after the stitches are supposed to be removed, it is essential to understand what this could mean and what steps you should take.

First, if the stitches are dissolvable, they are designed to break down on their own over time, usually within a week or two. If you see a piece of black thread, it may be a part of the dissolvable stitch that has not yet dissolved. In some cases, these stitches can take longer to dissolve, especially if the area is not healing as quickly as expected. If the stitches are non-dissolvable, they will need to be removed by your dentist or oral surgeon.

The presence of a stitch on your gums, particularly near your second molar, may not necessarily indicate a problem. However, it is crucial to monitor the area for any signs of infection or complications. Symptoms to watch for include:
1. Increased Pain: If the area becomes increasingly painful rather than improving, this could indicate an issue.

2. Swelling: Some swelling is normal after surgery, but significant or worsening swelling could be a sign of infection.

3. Discharge: If you notice pus or any unusual discharge from the extraction site, this could be a sign of infection.

4. Fever: A fever may indicate an infection and should be addressed promptly.

If you are concerned about the remaining stitch or if you experience any of the symptoms mentioned above, it is advisable to contact your dentist or oral surgeon. They can assess the situation and determine whether the stitch needs to be removed or if any further treatment is necessary.

In terms of care after wisdom tooth extraction, here are some general guidelines to follow:
- Oral Hygiene: Maintain good oral hygiene but be gentle around the extraction site. Avoid brushing directly on the area for the first few days. After a week, you can gently brush the area if it feels comfortable.

- Rinsing: You can rinse your mouth with warm salt water starting 24 hours after surgery to help keep the area clean. Avoid vigorous rinsing that could dislodge the blood clot.

- Diet: Stick to soft foods for the first few days and avoid anything hard, crunchy, or spicy that could irritate the extraction site.

- Follow-Up: Attend any scheduled follow-up appointments to ensure proper healing.

In conclusion, if you have a stitch remaining after your wisdom tooth extraction, it is essential to monitor the area for any signs of complications. If you have concerns or experience any unusual symptoms, do not hesitate to reach out to your dental professional for guidance. They will provide the best advice tailored to your specific situation and ensure that your recovery proceeds smoothly.
