Root resorption is a condition in which biological or disease-related changes occur within the root of the tooth. There are two types of root resorption:
Internal resorption occurs when the loss of tooth structure is in the root canals of the tooth. Internal resorption can be caused by oral trauma or a bacterial infection. When internal resorption occurs, an individual may notice a pinkish tint to the affected tooth.
External resorption occurs when the loss of tooth structure is on the external surface of the tooth. Trauma, orthodontic treatment, or infection can cause external resorption.
Various factors are considered when treating root resorption. It's critical that treatment begins as soon as possible to prevent additional damage from occurring and to save the affected tooth. Root canal treatment may be recommended to you by your endodontist or dentist. If the tooth cannot be saved, extraction may be necessary.
Avoiding infection by regularly brushing and flossing your teeth and having routine dental cleaning can help prevent root resorption. In addition, individuals who play sports should wear a mouth guard to prevent dental trauma.
