Tooth extraction is a small surgery, for the use of anaesthetics, so that the extraction of teeth will not have pain, so now people no longer have a fear of tooth extraction, but after the extraction of teeth if you do not do a good job of care work, sometimes can cause some sequelae of tooth extraction, so after the extraction of teeth, we have to pay attention to the following aspects:

　　First, follow the doctor's advice, after the extraction of teeth to bite the pressure on the wound of the antiseptic cotton ball or gauze, in order to achieve the purpose of compression of the wound, to help stop the bleeding, to insist on half an hour before spitting out. This is because the blood in the wound after tooth extraction may form a blood clot within half an hour. If you spit out the cotton ball or gauze earlier, bleeding is likely to occur.

　　Do not touch the wound with your fingers after tooth extraction, because there are a lot of pathogenic microorganisms on your fingers, which can easily cause infection of the extraction wound and also destroy the blood clot that has been formed.

　　Second, do not rinse your mouth within 24 hours after extraction, not to mention brushing your teeth. Due to the extraction of teeth about 24 hours after surgery, the local fibroblast cells just from the alveolar bone wall to the blood clot extension growth, and gradually make the blood clot mechanisation and become solid and sturdy.

　　If you are in a hurry to rinse and brush your teeth, you may rinse out the blood clot, brush it off and cause bleeding again, or cause the socket to be empty and lead to unbearable pain "dry socket", prolonging the healing time. Care should also be taken not to lick the wound with the tongue or suck the wound with force to prevent the wound from becoming infected or to dislodge the blood clot on the wound, which may affect the coagulation process and cause continuous bleeding.

　　Third, two hours after tooth extraction can eat, but should pay attention to eat some liquid food, do not drink hot water or eat too hot, too hard food. Hot food will cause vasodilatation and easy to bleed; too hard food is a mechanical stimulation of the wound, which can cause bleeding and aggravate the injury, so it should be avoided.

　　Fourth, do not smoke a few days after tooth extraction, because cigarette smoke on the extraction wound will also produce harmful stimulation, affecting the coagulation process, and do not drink alcohol or eat spicy and other stimulating foods, so as not to aggravate pain or bleeding. Never use unsterilised paper, cotton, tooth powder, etc. to insert into the extraction wound.

　　Fifth, after tooth extraction, if the wound bleeding or spitting blood from time to time, you can take a simple way to stop bleeding, such as using a clean cold towel or dipped in ice water gauze on the side of the face of the tooth extraction, the local blood vessels encounter cold stimulation will contract on its own and stop bleeding. You can also use a sterilised cotton ball or gauze to stop the bleeding by stuffing it on the wound and biting it with a little force. If you can't control it, ask your doctor to deal with it as soon as possible.

　　Sixth, the use of medication must be used under the guidance of a doctor. Slight pain after tooth extraction is normal, you can take pain relief tablets as appropriate.
