Traumatic dental injuries often result from sports injuries and accidents. Major types include a chipped tooth, a partially dislodged tooth, and an avulsed tooth (total knockout of a tooth from its socket), or abscessed teeth.
A chipped tooth is often a minor injury, but checking with a dentist is recommended. The injury may superficially seem like only the chipped tooth is affected, whereas nearby teeth and tissues may suffer unnoticed injuries. Dental exams can help detect any superficially obscured injuries.
Dislodged or avulsed teeth are more serious and can cause a complication called root resorption. Root resorption happens when the immune system no longer recognizes a tooth as a part of the body. The immune system treats the tooth like a foreign invader and fights it, resulting in pain and toothache, swollen gums, tooth discoloration, and tooth shifting. To prevent repulsion, a dentist or endodontist may provide preemptive treatment and frequently monitor the patient's dental health for up to five years.
