Tooth socket (lat. alveolus) - (literally) “hollow hole”, literal translation “tooth pit”.
The socket of a tooth is a depression in the bone tissue of the jaw where the tooth is located. This is a shallow depression bounded by the dental alveolar process. It is a reservoir for the pulp tissue of the tooth, in which blood vessels and nerve endings are located.
As you know, teeth are formed from unformed tooth germs located in the jaw. These rudiments are elongated pieces of bone tissue connected to each other by cell division. When the embryo becomes an adult, the cells begin to multiply by division, while they expand and increase in size. This process is called growth.
