The interdisciplinary team is often confronted with the decision of whether to retain or remove questionable teeth that have already been treated endodontically. The purpose of this article is to review the restorative criteria that must be met in order for these teeth to be predictable over the long term. In many instances, the decision of whether to restore or remove a tooth is quite clear. Untreatable periodontal conditions, untreatable endodontic conditions, unmanageable root resorption, or root fractures make the decision to remove a tooth an easy one. For the purpose of this article the author is going to assume that the teeth in question are treatable endodontically as well as periodontally and focus specifically on the issues of restorative predictability.
