Tooth resorption
Tooth Resorption
Tooth resorption (/tuːθ rɪˈzɔːrpʃən/) is a process by which the dentin and cementum, the hard tissues of the tooth, are broken down and absorbed into the body. The process can occur on any tooth in the oral cavity and can lead to the loss of the tooth if not treated promptly.
Etymology
The term "resorption" is derived from the Latin word "resorbere", which means "to swallow back". This refers to the body's process of absorbing its own tissues.
Types of Tooth Resorption
There are two main types of tooth resorption: internal and external.
- Internal Resorption occurs when the body begins to absorb the tooth from the inside out. This is often due to inflammation of the pulp, the innermost part of the tooth, which can be caused by trauma or infection.
- External Resorption is when the body absorbs the tooth from the outside in. This can be caused by factors such as pressure from orthodontic treatment, trauma, or inflammation of the periodontal ligament.
