Two of the most common complications of replantation of avulsed teeth are pulpal necrosis and root resorption. Treatment for these would involve performing root canal therapy. For several weeks after the accident, the tooth or teeth should be monitored clinically and radiographically. Some practioners may automatically begin root canal therapy within one to two weeks after the accident to minimize the chance of further cell damage. This may be the prudent course of treatment if the apex of the root was fully formed prior to implantation.
Prognosis is variable.
We may not be able to judge the success of reimplantation for many years. If root resorption continues after root canal therapy, the tooth will most likely be lost. Then, a fixed bridge, a removable partial denture, or an implant will need to replace the missing tooth. I strongly encourage all parents and coaches to educate student athletes about the benefits of wearing mouthguards during contact sports like basketball, football, boxing, and wrestling. A mouthguard can prevent loss of tooth structure, loss of teeth, and concussions.
