Wisdom tooth removal is a common dental procedure undertaken for various reasons, such as impaction or overcrowding. Some bleeding is a natural and expected part of the healing process after the extraction. This bleeding occurs as the mouth’s blood vessels are disrupted, leading to a protective blood clot.
Expected Bleeding After Wisdom Tooth Removal
Bleeding following wisdom tooth extraction follows a predictable timeline. Immediately after the procedure, bleeding will be at its heaviest for the first few hours. Within about 4 hours, the flow should significantly slow down. This initial bleeding allows for the formation of a blood clot in the empty socket, a necessary step for proper healing.
Over the next 24 to 48 hours, light oozing or pinkish saliva mixed with blood is common and should be minimal. This discoloration is not a cause for concern, indicating a small amount of blood seeping into the saliva. Some people may even notice slight bleeding when brushing their teeth or eating during the first few days, which is also normal. Beyond 48 hours, any continued bleeding should be mild and taper off.
Managing Bleeding and Knowing When to Seek Help
Managing post-extraction bleeding contributes to a smoother recovery. Immediately after surgery, a dentist will place a gauze pad over the extraction site. Bite down firmly for about 30 to 45 minutes to apply pressure and aid in clot formation. If bleeding continues, the gauze may need to be replaced every 30 to 45 minutes, ensuring it is placed directly over the bleeding area. Using a moistened tea bag, particularly one with tannic acid, can also be effective in stopping bleeding by constricting blood vessels and promoting clotting; it can be bitten on for 30 to 60 minutes.
To further minimize bleeding, keep your head elevated, especially when resting, as this reduces blood pressure in the area. Limiting physical activity for the first few days and avoiding actions that could dislodge the blood clot, such as vigorous rinsing, spitting, or using straws, is also important. Applying a cold compress to the cheek near the extraction site for 15-20 minute intervals during the first 24 hours can help constrict blood vessels and reduce bleeding.
While some bleeding is expected, certain signs indicate that professional medical attention may be needed. If heavy bleeding continues for more than 24 hours, or if you experience uncontrollable bleeding, contact your dentist. Signs of concerning bleeding include frequent gauze changes due to saturation, bright red blood, or large blood clots. Persistent, profuse bleeding that does not subside with direct pressure or is accompanied by severe pain, increasing swelling, or a foul odor could indicate dry socket or infection, requiring immediate dental evaluation.
