State of the art dentistry uses CAD/CAM. 3D imaging creates base model which is tweaked by dental technician then created in an automatic milling machine. Takes about 45 minutes and eliminates a second visit (think one round of anesthesia).

Not sure that 3D printing could make anything nearly as strong as necessary for a tooth.
