If a tooth has been broken or damaged by decay, your dentist will try to fix it with a filling, crown or other treatment. Sometimes, though, there's too much damage for the tooth to be repaired. This is the most common reason for extracting a tooth.
Here are other reasons:
- Some people have extra teeth that block other teeth from coming in.
- People getting braces may need teeth extracted to create room for the teeth that are being moved into place.
- People receiving radiation to the head and neck may need to have teeth in the field of radiation extracted.
- People receiving cancer drugs may develop infected teeth. These drugs weaken the immune system, increasing the risk of infection. Infected teeth may need to be extracted.
- People receiving an organ transplant may need some teeth extracted if the teeth could become sources of infection after the transplant. People with organ transplants have a high risk of infection because they must take drugs that decrease or suppress the immune system.
How is it done?
A simple extraction is performed on a tooth that can be seen in the mouth. General dentists commonly do simple extractions. Most of these can be done using just an injection (a local anesthetic), with or without anti-anxiety drugs. In a simple extraction, the dentist will grasp the tooth with forceps and loosen it by moving the forceps back and forth. Then the tooth will be pulled out. Sometimes the dentist will use a dental "elevator" to help loosen the tooth. This is an instrument that fits between the tooth and the gum.
Follow-up
Most simple extractions do not cause much discomfort after the procedure. You may take an over-the-counter nonsteroidal anti-inflammatory drug (NSAID) such as ibuprofen (Advil, Motrin and other brand names) for several days. You may not need any pain medicine at all.
A cut in the mouth tends to bleed more than a cut on the skin because it cannot dry out and form a scab. After an extraction, you'll be asked to bite on a piece of gauze for about 20 to 30 minutes. This will put pressure on the area and allow the blood to clot. It still may bleed a small amount for the next 24 hours or so and taper off after that. Don't disturb the clot that forms on the wound.
You can put ice packs on your face to reduce swelling after the operation. If your jaw is sore and stiff after the swelling goes away, try warm compresses. Eat soft and cool foods for a few days. Then try other food as you feel comfortable. 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 swelling and bleeding end within a day or two after the surgery. Initial healing takes at least two weeks.
You should not smoke, use a straw or spit after surgery. These actions can pull the blood clot out of the hole where the tooth was. That causes more bleeding and can lead to a dry socket, which occurs in about 3% to 4% of all extractions. Dry socket occurs 20% to 30% of the time when impacted teeth are removed. It happens more often in smokers and women who take birth control pills. It is also more likely after difficult extractions.
