Essential for the prognosis of an avulsed permanent tooth is the conduct at the site of the accident. The type and duration of extraoral storage of the tooth prior to replantation have an impact on the survival of the periodontal cells on the root surface and on the probability of revascularisation of the pulp in case of an immature tooth with a wide-open apical foramen (>2 mm). In order to secure the survival of the periodontal cells for a longer period of time (up to 24 hours), the avulsed tooth should immediately be placed in the transport medium for organs in a tooth rescue box.

Treatment of an avulsed permanent tooth has to be handled as an emergency case in private practice. Since children and adolescents are most often affected, replantation of the tooth is the preferred treatment. Numerous factors like the chain of rescue, the condition of the tooth, the diameter of the apical foramen, any intraoral accompanying injuries and the age of the patient all influence the exact procedure. By means of local and systemic drug intervention in terms of antiresorptive regenerative therapy, periodontal healing and the probability of revascularisation of the immature tooth may be influenced in a positive way.
