Why You Get Stitches After Wisdom Teeth Removal
Stitches close the gum tissue after wisdom teeth are extracted. When a wisdom tooth is removed, especially an impacted tooth that required cutting into the gum and bone, the surgeon needs to close the surgical site to protect the underlying bone and blood clot.
Stitches serve several purposes. They hold the edges of the gum tissue together so healing occurs from edge to edge rather than from the bottom of the wound up. They help control bleeding by applying gentle pressure to the tissue. They also protect the blood clot that forms in the socket, which is essential for normal healing. Without this clot, the bone and nerves become exposed, a painful condition known as dry socket.
Not every wisdom tooth extraction requires stitches. Simple extractions where the tooth is fully erupted and comes out intact may not need sutures. However, most surgical extractions of impacted or partially impacted wisdom teeth do.
Types of Stitches Used After Wisdom Teeth Removal
The type of stitches your oral surgeon uses depends on the complexity of the extraction, their clinical preference, and how your tissue needs to heal.
Dissolvable (Absorbable) Stitches
Dissolvable stitches are the most commonly used type for wisdom teeth removal. They are made from materials that the body naturally breaks down over time, such as polyglycolic acid (Vicryl) or chromic gut. You do not need a return visit to have them removed.
These stitches lose their strength gradually as enzymes in your saliva and tissue break them down. You may notice the stitches loosening, fraying, or falling out in pieces. This is normal and expected. Some patients barely notice them dissolving, while others find small pieces of suture material in their mouth.
Non-Dissolvable (Non-Absorbable) Stitches
Non-dissolvable stitches are made from materials like nylon or silk that the body does not break down. They require a follow-up appointment for removal, typically 7 to 10 days after surgery. Removal is quick and usually painless.
Some oral surgeons prefer non-dissolvable stitches for more complex extractions because they maintain their strength throughout the critical early healing period. They provide consistent tension and hold tissue securely without weakening as the wound heals.
When Do Wisdom Teeth Stitches Dissolve?
Dissolvable stitches typically begin to loosen around day 5 to 7 after surgery. Most are fully dissolved or have fallen out by day 10 to 14. The exact timeline depends on the type of suture material used and your body's healing rate.
Chromic gut sutures tend to dissolve faster, often within 5 to 10 days. Vicryl sutures maintain their strength longer and may take 10 to 14 days to fully break down. Your oral surgeon can tell you which type they used and what dissolving timeline to expect.
If a dissolvable stitch is still present after 2 weeks and is bothering you, contact your surgeon's office. They can remove it quickly at a brief appointment. Sometimes a suture knot remains after the rest of the stitch has dissolved, and this can be clipped easily.
How to Care for Your Stitches After Surgery
Proper care of the surgical site and stitches reduces the risk of infection and promotes faster healing. The first 48 hours are the most critical.
The First 48 Hours
Do not rinse, spit forcefully, or use a straw for the first 24 hours. These actions create suction or pressure in the mouth that can dislodge the blood clot and loosen stitches. Avoid touching the stitches with your tongue or fingers. Eat soft, cool foods such as yogurt, applesauce, and smoothies (eaten with a spoon, not a straw).
If you notice mild oozing or a pink tinge to your saliva during the first day, this is normal. Bite down gently on a gauze pad for 30 to 45 minutes to help control any bleeding. If heavy bleeding continues after an hour of steady pressure, contact your surgeon.
Days 2 Through 7
Starting 24 hours after surgery, begin gentle saltwater rinses. Dissolve half a teaspoon of salt in 8 ounces of warm water and let the solution flow gently over the surgical sites. Do not swish vigorously. Rinse after meals and before bed to keep food debris away from the healing areas.
Continue eating soft foods and gradually introduce firmer foods as comfort allows. Avoid crunchy, spicy, or very hot foods that could irritate the surgical sites. Brush your other teeth normally but be very gentle around the extraction areas.
Week 2 and Beyond
By the second week, dissolvable stitches should be mostly gone and the gum tissue should be closing over the extraction sites. You can gradually return to your normal diet and brushing routine. Some tenderness and minor swelling may persist for 2 to 3 weeks, but the worst of the discomfort should be behind you.
What If a Stitch Comes Out Early?
A stitch coming out before the tissue is fully healed is one of the most common concerns patients have after wisdom teeth removal. In most cases, it is not an emergency.
If a stitch falls out in the first 1 to 2 days, check the extraction site for active bleeding. If bleeding is minimal or absent and you can see a dark blood clot in the socket, the site is likely healing normally. Continue your aftercare routine with gentle saltwater rinses.
If a stitch comes out and you notice significant bleeding that does not stop with 30 to 45 minutes of gauze pressure, or if you can see bare bone in the socket, contact your oral surgeon. They may need to evaluate the site and determine if a replacement suture or additional treatment is necessary.
Losing one or two stitches early does not automatically mean your healing will be compromised. Stitches support healing, but the blood clot and your body's natural tissue repair process do most of the work.
Signs of Infection and When to Call Your Surgeon
Some discomfort and swelling are normal after wisdom teeth removal. Knowing the difference between normal recovery and a complication helps you respond appropriately.
Normal Healing Signs
Swelling that peaks around day 2 to 3 and then gradually improves. Mild to moderate pain that responds to prescribed or over-the-counter medication. Bruising on the cheeks or jaw. Stiffness when opening the mouth. A slight pink tinge to saliva for the first day or two.
Warning Signs That Need Attention
Contact your oral surgeon if you experience any of the following: pain that gets worse after the first 3 to 4 days instead of improving, swelling that increases after day 3, a bad taste in your mouth or visible pus around the surgical site, fever above 101 degrees Fahrenheit, numbness or tingling in your lip, chin, or tongue that persists beyond 24 hours, or heavy bleeding that does not stop with gauze pressure.
Dry Socket
Dry socket (alveolar osteitis) occurs when the blood clot in the extraction site is lost or dissolves before the tissue has healed. Symptoms include severe, throbbing pain that starts 2 to 4 days after surgery, often radiating to the ear. You may be able to see exposed bone in the socket. Dry socket requires treatment from your oral surgeon, who will clean the area and apply a medicated dressing to promote healing and relieve pain.
When to See an Oral Surgeon for Wisdom Teeth Removal
While some general dentists remove wisdom teeth, an oral surgeon is the specialist trained for complex extractions. Impacted wisdom teeth, teeth positioned close to nerves, and cases requiring bone removal are best handled by an oral and maxillofacial surgeon. These specialists complete 4 to 6 years of residency training beyond dental school, with extensive experience in surgical extractions and anesthesia.
If you have been told your wisdom teeth need to come out, a consultation with an oral surgeon will give you a clear picture of the surgical plan, the type of anesthesia recommended, and what to expect during recovery.
