How does the periodontium work?
The periodontium keeps our teeth firmly in place in the mouth. It is made up of four parts:
- Tooth sockets (dental alveoli)
- Periodontal ligament
- Gums (gingiva)
The holes in the jaws that contain the roots of the teeth are called tooth sockets, or dental alveoli. The jaws and the walls of the tooth sockets are made up of bone tissue. This part of the periodontium is not usually visible.
