The mold body includes a facial portion forming a facial surface corresponding with a facial surface of the tooth, and a separate lingual portion forming a lingual surface corresponding with a lingual surface of the tooth. 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. ## Claims ### Claim 1 A custom tool for forming a dental restoration in a mouth of a patient, the custom tool comprising: a mold body providing for a customized fit with at least one tooth of the patient, the mold body including a facial portion forming a facial surface corresponding with a facial surface of the tooth, and further including a separate lingual portion forming a lingual surface corresponding with a lingual 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. ### Claim 2 (depends on 1) The custom tool of claim 1, wherein the facial portion is separable from and engageable with the lingual portion. ### Claim 3 (depends on 1) The custom tool of claim 1, wherein the custom tool forms a proximal surface corresponding with a proximal surface of a first adjacent tooth. ### Claim 4 (depends on 3) The custom tool of claim 3, wherein the facial portion forms the proximal surface, wherein the proximal surface corresponds with a proximal surface of the first adjacent tooth. ### Claim 5 (depends on 3) The custom tool of claim 3, wherein the lingual portion forms the proximal surface, wherein the proximal surface corresponds with a second adjacent tooth. ### Claim 6 (depends on 1) The custom tool of claim 1, further including an occlusal portion including an occlusal surface, wherein the occlusal surface corresponds with an occlusal surface of the tooth. ### Claim 7 (depends on 6) The custom tool of claim 6, wherein the facial portion, lingual portion, and occlusal portion are all customized to fit around a tooth receiving a restoration. ### Claim 8 (depends on 7) The custom tool of claim 7, further including a tooth receiving the restoration in the patient's mouth. ### Claim 9 (depends on 1) The custom tool of claim 1, wherein the facial portion and the lingual portion are based on three-dimensional scan data of the mouth of the patient. ### Claim 10 (depends on 9) The custom tool of claim 9, wherein the facial portion and the lingual portion are manufactured by three-dimensional printing. ### Claim 11 (depends on 1) The custom tool of claim 1, wherein the facial surface and the lingual surface together form an inner surface corresponding to the tooth's outer surface prior to restoration. ### Claim 12 (depends on 1) The custom tool of claim 1, further comprising a dental restorative material located within the mold cavity. ### Claim 13 (depends on 1) The custom tool of claim 1, wherein the custom tool forms a gingival surface corresponding with gingiva surrounding the tooth. ### Claim 14 (depends on 13) The custom tool of claim 13, wherein the custom tool retracts the gingiva from the tooth for a restoration of the tooth. ### Claim 15 (depends on 1) The custom tool of claim 1, wherein the facial portion and lingual portion assist in separating the first adjacent tooth and a second adjacent tooth from the tooth receiving the restoration. ### Claim 16 (depends on 1) The custom tool of claim 1, wherein the facial portion and lingual portion isolate the tooth receiving the restoration from blood or saliva. ### Claim 17 (depends on 1) The custom tool of claim 1, wherein the facial portion and lingual portion are manufactured by CAD/CAM milling processes. ### Claim 18 (depends on 1) The custom tool of claim 1, further including a dental restorative material fill level indicator for the tooth receiving the restoration. ### Claim 19 (depends on 1) The custom tool of claim 1, wherein the facial surface and the lingual surface correspond to outer surfaces of the tooth prior to restoration of the tooth. ### Claim 20 (depends on 1) The custom tool of claim 1, wherein the facial portion engages and disengages along the mesial-distal arch of the mouth of the patient. ### Claim 21 (depends on 1) The custom tool of claim 1, wherein the facial portion is a buccal portion. ### Claim 22 (depends on 1) The custom tool of claim 1, wherein the facial portion is a labial portion. ### Claim 23 (depends on 1) The custom tool of claim 1, wherein the custom tool forms an occlusal surface corresponding with an occlusal surface of the tooth. ### Claim 24 (depends on 1) The custom tool of claim 1, wherein the at least one tooth is a plurality of teeth, wherein the mold cavity is a first mold cavity adjacent a first one of the plurality of teeth, and wherein the mold body is configured to combine with a second one of the plurality of teeth to form a second mold cavity encompassing missing tooth structure of the second one of the plurality of teeth. ### Claim 25 (depends on 1) The custom tool of claim 1, wherein the mold cavity is adjacent one of more of a group consisting of: an occlusal or incisal surface of the tooth; the lingual surface of the tooth; and the facial surface of the tooth. ### Claim 26 (depends on 1) The custom tool of claim 1, wherein the custom tool is the first custom tool in a set of custom tools that combine to facilitate a dental restoration of the tooth of the patient, wherein mold cavity is a first mold cavity, and wherein a second custom tool in the set of substantially similar custom tools combines with the tooth as well as dental restorative material layered on the tooth using the first custom tool to form a second mold cavity configured to encompasses additional missing tooth structure of the tooth. ### Claim 27 (depends on 1) The custom tool of claim 1, wherein the mold body forms a port leading to the mold cavity, wherein the port is configured to receive an injection of dental restorative material. ### Claim 28 (depends on 27) The custom tool of claim 27, wherein the mold body forms a vent port configured to facilitate the venting of the mold cavity during the injection of dental restorative material. ### Claim 29 (depends on 1) The custom tool of claim 1 comprising an element, the location of the element being selected on the basis of optical scan data, the element selected from a group consisting of: a parting line; an injection port; a vent; a gate; and a boundary line. ### Claim 30 (depends on 1) A kit for forming a dental restoration within the mouth of a patient comprising: the custom tool of claim 1; and dental restorative material. ### Claim 31 (depends on 30) The kit of claim 30, further comprising a dental capsule including a cannula adapter to fit with a port on the custom tool, wherein the dental restorative material is provided in the dental capsule. ### Claim 32 (depends on 30) The kit of claim 30, further comprising adhesive. ### Claim 33 (depends on 30) The kit of claim 30, further comprising a matrix band. ### Claim 34 (depends on 30) The kit of claim 30, further comprising: a pad;
