You may be surprised to learn that you might lose pieces of your teeth. While this may sound like something out of a horror movie, some dental traumas or irritations can cause sections of your tooth to degenerate. The enamel, dentin, cementum, pulp, and root can all be affected by this process known as dental resorption. Dental resorption usually begins on the tooth’s exterior and progresses inside; however, this is not always the case.
