There are two main categories of tooth resorption:
Internal resorption:
This begins inside the tooth and involves changes within the root canal space. Treatment often involves root canal therapy to remove the affected tissue and seal the tooth.
External resorption:
This begins on the outside surface of the root. Treatment depends on the location and severity and may involve monitoring, surgical treatment, root canal therapy, or a combination of approaches.
An accurate diagnosis is essential because treatment differs significantly depending on the type of resorption present.
