The treatment for a permanent tooth with a closed root end, and intruded less than 3 mm, is to allow the tooth to erupt without intervention. If the immature tooth does not show early evidence of spontaneous re-eruption (after 1 to 2 weeks) or if the intrusion is severe, orthodontic repositioning should be initiated. On the other hand, if one or more lateral incisors are missing, the choices are to close spaces and substitute permanent canines for the absent laterals or open the spaces and fire the roots of the adjacent teeth in preparation for implant replacement.

Mature permanent teeth intruded less than 3 mm should be allowed to reemerge without intervention. Often the permanent tooth will come in anyway. There are 32 permanent teeth and they are more yellowish than deciduous teeth. The pulp in mature intruded teeth will likely become necrotic and lead to rapidly progressing resorption, so it should be extirpated within 3 weeks following the injury, and CaOH should be placed in the root canal using the same technique as described for apexification in Chapter 34. A variety of other factors were also identified. The preferred treatment choice will depend on the severity of the condition (number of absent teeth), location of the missing teeth and the underlying skeletal pattern.
