1. A process of making a custom tool for forming a dental restoration of a tooth within a mouth of a patient, the process comprising:
obtaining three dimensional scan data of a patient's mouth; and
three-dimensionally printing a custom tool for forming the dental restoration of the tooth based on the three dimensional scan data of the mouth of the patient, wherein the custom tool comprises:
a mold body providing for a customized fit with at least one tooth of the patient, the mold body including an occlusal portion forming an occlusal surface corresponding with an occlusal surface of the tooth, a mesial proximal portion forming a mesial proximal surface corresponding with a mesial proximal surface of the tooth, a distal proximal portion forming a distal proximal surface corresponding with a distal proximal surface of the tooth, and a port and a plug, wherein the plug includes a tip surface corresponding to a surface of the tooth,
wherein the mold body is configured to combine with the tooth of the patient to form a mold cavity encompassing missing tooth structure of the tooth,
wherein the occlusal portion, the mesial proximal portion, and the distal proximal portion are based on three-dimensional scan data of the mouth of the patient, and the occlusal portion, the mesial proximal portion, and the distal proximal portion form a one-piece portion that fits over the at least one tooth of the patient.
