Dissolvable stitches after wisdom tooth extraction typically fall out on their own within 7 to 10 days, though some types take up to a month to fully dissolve. The exact timeline depends on the suture material your surgeon used and how quickly your body breaks it down.
Typical Dissolution Timeline
Most people notice their stitches loosening or falling out around the one-week mark. You might feel a small thread in your mouth while eating or brushing, and that’s completely normal. The stitches have usually done their job by this point, holding the tissue in place long enough for the early stages of healing.
The material matters. Natural gut sutures break down through enzymatic activity in your saliva and typically dissolve fastest. Synthetic stitches made from polyglycolic acid, one of the most common materials used in oral surgery, are broken down by a chemical process called hydrolysis that takes 21 to 28 days inside the mouth. So if your stitches are still hanging around at two or three weeks, that’s well within the normal range. Some people don’t see the last traces disappear for a full month.
How the Stitches Actually Break Down
Your mouth is a surprisingly effective environment for dissolving sutures. Saliva contains enzymes that actively digest natural suture materials, while the constant moisture breaks apart synthetic ones at the molecular level. The warm, wet conditions inside your mouth speed this process along compared to stitches placed elsewhere on the body. You won’t feel the stitches dissolving. They gradually weaken, fray, and fall apart in small pieces that you’ll either spit out or swallow harmlessly.
What If Stitches Come Out Early?
It’s common for a stitch to come loose within the first few days, especially if it catches on food. If this happens before the 3-day mark, contact your surgeon’s office. They’ll want to check whether the incision still needs support.
If your stitches fall out between days 3 and 10, they’ve generally already served their purpose. The key factor is whether the extraction site looks like it’s healing properly. If the gum tissue appears to be closing and there’s no visible gap at the incision, a replacement stitch usually isn’t necessary. If the incision still looks open, your surgeon may need to place a new one.
Non-Dissolvable Stitches Are Different
Not every surgeon uses dissolvable sutures. Some prefer silk or nylon stitches, which won’t break down on their own and require a quick office visit for removal. If your surgeon used non-dissolvable stitches, you’ll typically have them taken out within 7 to 10 days. The removal process is fast and generally painless. Your surgeon should tell you at the time of your extraction which type was used, so if you’re unsure, call the office and ask.
Caring for Your Stitches While They Dissolve
The goal during the first week is to keep the surgical site undisturbed so the blood clot stays in place. That clot is what protects the exposed bone and allows healing to begin. Losing it too early leads to a condition called dry socket, which causes significant pain (though it’s treatable with a medicated dressing placed at your surgeon’s office).
For the first 24 to 48 hours, avoid rinsing, spitting forcefully, or using a straw. All of these create suction that can dislodge the clot. After that initial period, gentle saltwater rinses help keep the area clean without putting stress on the stitches. Stick to soft foods and chew on the opposite side of your mouth. Avoid poking at the stitches with your tongue or fingers, even if they feel loose or irritating.
Signs Something Isn’t Right
Some swelling and discomfort in the first two to three days is expected. What you’re watching for are symptoms that get worse after initially improving. The American Association of Oral and Maxillofacial Surgeons identifies these signs of infection: fever, increasing pain, worsening swelling (especially if it feels fluid-filled), a persistent salty or foul taste, and pus at the surgical site. White or yellow discharge from the area, a bad odor, or swollen glands in your neck also warrant a call to your surgeon.
Pain that spikes three to four days after surgery, particularly if you notice a foul taste and can see the empty socket, may indicate dry socket rather than infection. Either way, contact your surgeon’s office. Both conditions are manageable but benefit from prompt treatment.
