Wisdom teeth removal is a common dental procedure, and experiencing some bleeding afterward is a normal part of the healing process. The body initiates a natural response to close the surgical site and promote recovery. Understanding what to expect and how to manage this bleeding can help ensure a smoother post-operative experience.
What to Expect: Normal Bleeding After Extraction
Immediately following wisdom teeth removal, some bleeding is expected due to the disruption of blood vessels in the mouth. The initial bleeding may be most noticeable in the first few hours after the procedure. During this time, the body begins to form a blood clot at the extraction site, which is important for healing and protecting the underlying bone and nerves.
Over the first 24 hours, the bleeding should gradually lessen. While the heaviest flow occurs right after surgery, it should slow significantly within about four hours. Light oozing or saliva tinged with pink or red is common for up to 24 to 48 hours. Beyond this, any continued bleeding should be minimal and gradually taper off. Some minor, occasional bleeding might persist for up to one to two weeks as the site continues to heal.
Managing Bleeding at Home
Patients can take several steps to manage bleeding after wisdom teeth removal. Immediately after the procedure, a gauze pad will be placed over the extraction site; bite down firmly on this gauze for 30 to 60 minutes to apply pressure and aid in clot formation. If bleeding continues, replace the gauze with a clean, folded piece, dampened with water, and apply firm pressure for another 30 to 45 minutes. Repeat this process with fresh gauze as needed.
Elevating the head with pillows when resting helps reduce blood pressure, which can decrease bleeding. Applying a cold compress to the cheek for 20-minute intervals (20 minutes on, 20 minutes off) during the first 24 hours can also help constrict blood vessels and slow bleeding. To avoid dislodging the blood clot, avoid vigorous rinsing, spitting, or using straws for at least one week after surgery. Also, refrain from smoking, as this can significantly increase the risk of complications like dry socket.
When Bleeding Becomes a Concern
While some bleeding is normal, certain signs indicate abnormal bleeding requiring professional evaluation. Heavy, continuous bright red bleeding that does not slow down or stop after applying firm pressure with gauze for 45 minutes to an hour is concerning. If you need to change gauze frequently due to saturation, or if you observe large blood clots, this may signal an issue with clot formation.
Bleeding accompanied by worsening pain, fever, or swelling that spreads to other parts of the face also warrants immediate attention. A persistent bad taste or odor, pus, or ooze from the extraction site could indicate an infection. If any of these symptoms occur, contact your oral surgeon or dentist promptly for further evaluation and guidance.
