Observing a black or dark patch near a recent tooth extraction site can be alarming, but this discoloration is common after a tooth removal. While the dark color might suggest something is wrong, it is frequently a normal part of the body’s natural healing process, indicating the correct formation of protective structures for recovery.
Normal Healing and the Blood Clot
The most frequent reason for a black appearance in the socket is the presence of the blood clot, known as a coagulum. This clot is a dense, jelly-like plug that forms immediately after the tooth is pulled, filling the empty space where the tooth root once sat. The clot is a mixture of red blood cells, platelets, and a sticky protein called fibrin, all working together to form a bandage for the wound.
The clot’s function is necessary; it shields the underlying jawbone and nerve endings from the oral environment, preventing a painful condition called dry socket. Because it is essentially concentrated, dried blood, it appears dark red, deep brown, or even black against the pink gum tissue. This color is expected and confirms that the initial stage of healing is progressing.
As the healing advances, the clot begins to transition into granulation tissue, which acts as a scaffold for new gum and bone growth. Around two to four days after the procedure, the dark clot may develop a gray or yellowish film on its surface. This film is often not pus or infection, but a layer of white blood cells and fibrin that are actively cleaning and organizing the wound for the next stage of repair. The dark material will gradually be replaced by new, healthy pink tissue over the course of several weeks.
Bruising and Residual Materials
If the dark spot is flat and spread across the gum tissue itself, rather than confined within the socket, it is likely a hematoma, which is simply a bruise. The force and manipulation required during a tooth extraction can cause trauma to the soft tissues and blood vessels surrounding the site. Blood leaks into the gum tissue, resulting in a discoloration that can appear deep purple, blue, or black.
Like any bruise on the body, this discoloration will change color over several days, shifting to green and yellow as the body reabsorbs the trapped blood components. This type of bruising is temporary and will fade entirely as the gum heals, usually resolving within one to two weeks.
Another distinct cause for a permanent dark spot is an amalgam tattoo, a small, localized area of gray, blue, or black pigmentation. This occurs when tiny particles of silver filling material, or amalgam, become lodged in the soft tissue during the extraction procedure. The metal fragments, which contain silver, tin, and copper, stain the gum tissue permanently. An amalgam tattoo is harmless and requires no treatment, but it is a lasting cosmetic change.
Signs of Complications
While a dark appearance is often normal, it is important to recognize signs that indicate a possible complication requiring dental attention. The most common concern is a dry socket, which occurs when the protective blood clot is dislodged or dissolves prematurely, exposing the bone. If you experience intense, throbbing pain that worsens two to four days after the extraction, especially pain that radiates to your ear or temple, you should contact your dentist.
Other symptoms, particularly when paired with a dark or discolored site, suggest a potential infection. These warning signs warrant an immediate call to your dental office:
- A persistent, foul odor or a bad taste in the mouth that cannot be rinsed away.
- Rapidly increasing swelling in the face or gum.
- A general feeling of malaise or a fever.
- Gray or white tissue that appears to be sloughing off, which could indicate tissue death.

If the dark tissue appears gray or white and seems to be sloughing off, this could indicate a rare, localized issue with tissue death that needs professional evaluation.
