Endodontically treated teeth with the loss of coronal tooth structure when left untreated for a long period may cause supraeruption, drifting, tipping, and rotation of adjacent and opposing teeth. This may be challenging to the clinician, when fabricating a crown because of inadequate interocclusal space. This case report describes a simple technique to restore an endodontically treated maxillary first premolar with the loss of coronal tooth structure and lack of interocclusal space. The maxillary first premolar had a single root canal and was endodontically treated. The lower premolar had supraerupted reducing the interocclusal space. A minimally invasive and esthetic technique was used to restore the tooth with limited interocclusal clearance. The tooth was restored with a Richmond crown, which had the morphology of a canine instead of a premolar. Thus, the tooth was salvaged by changing the morphology of the crown and the desired functional and esthetic results were obtained.
