A dentist, depending on the condition of the tooth, extracts the tooth. The dentist will try to fix a damaged tooth with a filling, crown or other treatment. Sometimes, though, there's too much damage for the tooth to be repaired. In this case, the tooth needs to be extracted. A very loose tooth also will require dental extraction if it can't be saved, even with bone replacement surgery. Some teeth may need to be extracted if they could become a source of infection after an organ transplant. People with organ transplants have a high risk of infection because they must take drugs that decrease or suppress the immune system. Most simple extractions can be done using just an injection (a local anesthetic). You may or may not receive drugs to help you relax. For a surgical extraction, you will receive a local anesthetic, and you may also have anesthesia through a vein (intravenous). Some people may need general anesthesia for the tooth to be pulled out. They include patients with specific medical or behavioral conditions and young children. A gentle rinse with warm salt water, started 24 hours after the surgery, can help to keep the area clean. Use one-half teaspoon of salt in a cup of water. Most of the swelling and bleeding comes down within a day or two after the surgery. Initial healing takes at least two weeks. The dentist may recommend painkillers and an antibacterial mouthwash. You may be prescribed some antibiotics, to reduce your chances of developing an infection.
