Please describe to me the healing process after a tooth extraction?

Simplistic answer : Blood clot will form in the socket(s) where the root(s) of the tooth was/were. Within 48 hrs changes happens in the clot. Bone cell started to form and bone production begins. Also there is a formation of gum tissue at the top. Within weeks the socket is closed and healed. But the bone level is lower than the original height. And will continue to resorb. Therefore it is better to keep the tooth.

Blood clot is formed: A blood clot is formed. The blood clot covers the extraction site and allows the area to heal. It usually takes gum tissue about 3-4 weeks to heal. The bone can take up to 6 months to heal completely. However, it depends on how easy or difficult the tooth removal was.
