What does this mean?
After an extraction the socket fills with blood, and within a few minutes that blood clots and covers the wound. Light bleeding in the form of oozing carrying on through the first hours is an expected course. One drop of blood mixed with saliva colours the whole mouth red, which is why the amount almost always looks far greater than it is.
What sets it apart is not saliva turning pink but the mouth filling up. In real bleeding the mouth fills again a few minutes after it has been emptied, gauze is soaked through within fifteen minutes, you have to keep swallowing, and the clot grows as a jelly-like mass hanging down. That mass does not stop the bleeding; on the contrary, it keeps the pressure from reaching the socket.
The second detail is where the pressure is applied. The gauze needs to sit directly on top of the extraction socket; a thick pad placed between the teeth that does not touch the socket will not stop the bleeding. Blood-thinning medicines, high blood pressure, hot showers, heavy work, rinsing and smoking are the main things that make it harder for a new clot to hold.
Bleeding carrying on after an extraction is most often to do with the clot failing to settle. Pressure applied to the wrong spot, the medicines you take, blood pressure and conditions that affect clotting all shape the picture together.
Likely causes
What helps at home?
- Roll a clean piece of gauze, place it directly over the extraction socket, bite down firmly and hold it for thirty minutes without opening once
- Do not rinse your mouth, spit, drink through a straw or smoke; each of these pulls the newly formed clot out of place
- Sit upright and keep your head raised; hot showers, heavy lifting, sport and hot drinks all increase bleeding
- Do not stop a blood-thinning medicine or any other regular medicine on your own decision; stopping is decided only together with the doctor
- If your mouth is still filling with blood after thirty minutes of correctly applied, uninterrupted pressure
- If the clot is growing as a jelly-like mass and hanging out of your mouth
- If you have dizziness, blacking out, palpitations or pale skin
- If you take a blood-thinning medicine and the bleeding has gone past two hours
- If there is swelling growing quickly in your face or neck, or you have difficulty swallowing or breathing
Frequently asked questions
- How much bleeding is expected?
- Saliva turning pink in the first hours is expected, and this light oozing can carry on for about a day. What is not expected is the mouth filling with blood again within a few minutes and not responding to correctly applied pressure. The measure is not the amount of blood you see but the response to pressure.
- How do I know I am applying pressure correctly?
- Roll the gauze and put it directly over the socket, not between the neighbouring teeth. Bite down firmly and, watching the clock, hold it for thirty minutes without opening once. Checking every few minutes tears away the clot that is forming each time and starts the process from the beginning.
- Should I stop my blood-thinning medicine?
- Do not stop it on your own decision. Stopping these medicines can have serious consequences such as a blocked blood vessel, and most extractions can be managed while the medicine carries on. If a change is needed, the doctor who prescribed it and your dentist decide together; the best time to discuss this is before the extraction.
