After wisdom tooth extraction, gauze helps control bleeding and encourages the formation of a blood clot. This clot acts as a natural protective barrier over the extraction site, preventing complications and promoting healing.
Initial Gauze Management
Following extraction, a sterile gauze pad is typically placed over the surgical area to apply pressure and help initiate clotting. Patients are usually advised to keep this initial gauze in place for about 30 to 45 minutes by biting down firmly. The pressure helps compress blood vessels, allowing a stable blood clot to form in the socket. Removing the gauze too soon can disrupt this crucial initial clot, potentially leading to a condition known as a dry socket.
When changing gauze, perform the action gently to avoid dislodging the newly formed clot. Carefully remove the old gauze. If significant bleeding continues, prepare a new, clean gauze pad by folding it into a compact square and placing it directly over the extraction site. Apply firm, consistent biting pressure on the new gauze for another 30 to 45 minutes. This process should be repeated every 30 to 45 minutes if active bleeding persists, until the bleeding substantially reduces.
Ongoing Gauze Use
Gauze is generally needed only as long as active bleeding or significant oozing is present at the extraction site. Active bleeding typically appears as a bright red flow that quickly soaks through multiple gauze pads. In contrast, a light pink tinge in saliva or minimal oozing on the gauze is considered normal and can persist for up to 24 to 48 hours after the procedure. Once the bleeding has slowed to this light pink tinge or has stopped entirely, and the gauze comes out mostly clean, it is usually safe to discontinue its use.
Most individuals find they can stop using gauze within the first one to four hours following surgery. If minor oozing continues but is not heavy, an alternative is to bite down gently on a damp black tea bag for 30 to 45 minutes. The tannins in black tea can help blood vessels constrict and promote clotting, assisting in controlling the oozing. Always remove gauze or tea bags when eating or sleeping to prevent choking.
When to Contact Your Dentist
While some bleeding and discomfort are expected after wisdom tooth extraction, certain signs indicate a need to contact your oral surgeon or dentist. You should seek professional guidance if you experience heavy, continuous bright red bleeding that soaks through multiple gauze pads quickly and persists beyond 24 hours. Similarly, worsening pain that does not improve with medication, or pain that significantly increases after a few days, warrants attention.
Other concerning symptoms include swelling that increases significantly after 48 to 72 hours, rather than subsiding. A fever, chills, pus discharge from the socket, a foul odor or bad taste in the mouth, and difficulty swallowing can also be indicators of a potential complication, such as an infection. If you notice these signs, contacting your dental professional promptly can help ensure proper healing and prevent further issues.
