Tooth extraction is the removal of a tooth from its socket in the bone. 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. In this case, the tooth needs to be extracted. A very loose tooth also will require extraction if it can't be saved, even with bone replacement surgery (bone graft).
Here are other reasons:
Your dentist or oral surgeon will take an X-ray of the area to help plan the best way to remove the tooth. Be sure to provide your full medical and dental history and a list of all medicines you take. This should include both prescription and over-the-counter drugs, vitamins and supplements. If you are having wisdom teeth removed, you may have a panoramic X-ray. This X-ray takes a picture of all of your teeth at once. It can show several things that help to guide an extraction.
It normally takes a few days to recover after a tooth extraction. The following steps help ensure that your recovery goes smoothly.
