After wisdom teeth removal, some bleeding is a normal part of the healing process. The body forms a blood clot to facilitate recovery. While the presence of blood can be concerning, understanding what to anticipate helps manage post-operative expectations.
Normal Bleeding Expectations
After wisdom teeth extraction, active bleeding should slow significantly within 2 to 4 hours. Light oozing or pink-tinged saliva may occur for up to 24 to 48 hours. Due to the mouth’s rich blood supply, a small amount of blood mixed with saliva can appear more substantial.
A blood clot forms within the empty socket, important for healing. This clot protects underlying bone and nerves from external elements like food particles and bacteria. It also forms the foundation for new tissue and bone growth, aiding site closure. A healthy clot typically appears dark red or brownish, resembling a scab.
Managing Bleeding at Home
To control bleeding and support clot formation, firmly bite down on gauze pads over the extraction sites. Consistent pressure is important. Change gauze every 30 to 45 minutes until bleeding significantly subsides. The pressure helps the blood clot form effectively.
Avoid activities that could dislodge the blood clot. Refrain from spitting, rinsing vigorously, or using straws for at least the first 24 hours after surgery. These actions create suction that can disrupt the delicate clot. Avoid hot liquids and strenuous physical activity for the first day, as these can increase blood flow and prolong bleeding. Applying a cold compress to the cheek near the extraction site for 20-minute intervals can help constrict blood vessels and reduce bleeding and swelling.
When to Seek Professional Advice
While some bleeding is expected, certain signs indicate professional medical attention is necessary. Contact your oral surgeon or dentist if you experience heavy, continuous bleeding that soaks through multiple gauze pads quickly and does not slow down after applying consistent pressure. Bleeding that persists or restarts heavily beyond 24 to 48 hours is also a reason for concern.
Other symptoms that warrant contacting your dentist include severe pain that is not managed by prescribed medication or worsens over time, especially if accompanied by a foul odor. A fever, excessive swelling that increases after 48-72 hours, or any pus-like discharge from the surgical site can indicate an infection. These signs suggest a possible complication, such as a dislodged blood clot (dry socket) or infection, which requires professional assessment and treatment.
