Trauma to the teeth occurs very often during sports or in an accident. The type of the dental injury is very variable depending on the severity of the blow. It varies from a chipped tooth to complete  avulsion  of a tooth. (knocked out completely)

Treatment depends on the type, location and severity of the injury. It depends also whether it is a permanent tooth or a primary tooth. In permanent teeth, the stage or maturity of the root formation is also very critical.

Immediate attention by a dentist or an Endodontist is very important for the prognosis and longevity   of the tooth.
