A tooth socket is called an alveolus in medical terms.
The fibrous connective tissue joining the tooth to the tooth socket is the periodontal ligament.
The part of the tooth that fits into the socket of the jaw(mandible) or maxilla(for upper teeth) is the "root" of the tooth.
The empty tooth socket following removal of the tooth.
Strong fibers known as the periodontal ligament (PDL) connect the root of the tooth to the socket. They help suspend the tooth in the socket, resist forces while chewing and grinding, and keep the tooth in place.
the reinsertion and splinting of a tooth that has been avulsed (knocked or torn out) of its socket
If you still feel what may be part of your tooth left in the socket, that is not good. I would suggest seeing your dentist, or oral surgeon about this as part of your tooth may have broken in the process of the extraction. If there is no partial tooth remaining, you may have what is called dry socket, which is extremely painful. This website will explain "dry socket" to you: http://www.dentalgentlecare.com/dry_socket.htm
To loosen or dislocate the tooth from the socket.
If the socket turns white after a tooth extraction, it means you have a dry socket. The white you are seeing is bone. After you have a tooth pulled, there is a socket or bone and sensitive nerves. Dry sockets occur when a blood clot either fails to form in the socket or it disintegrated. Dry sockets can lead to terrible pain and inflammation You should call your dentist right away if you have one!
