A dental device (such as a dental matrix or teeth tray) for use in in securing to one or more teeth during a dental restoration procedure or another dental procedure. In the case of a dental matrix, the dental matrix can be manufactured (e.g., in a dentist's facility using a three-dimensional printer apparatus or the like) after the targeted tooth of the patient in the dentist's facility is prepared for a filling material. As such, in some circumstances, the dental matrix is not necessarily a prefabricated metal band that is intended to be used with any of a variety of differently sized and shaped teeth of any of a variety of different patients, but instead the dental matrix may optionally be promptly fabricated according to the specific anatomical shape and size of a particular tooth of a particular patient while that patient is waiting in the dental chair.
