The present disclosure is generally directed toward a pontic material that is pliable and easily moldable, possesses a higher tear resistance to resist fragmenting and thus is long lasting, can be pigmented to achieve a good color match to adjacent teeth, and be fashioned into a pontic by the patient at home so as to free the orthodontist and their staff from having to do this purely aesthetic and time-consuming procedure. In addition, the pontic material of the present disclosure is typically permanently pliable so that an untrained person such as a patient would have unlimited time to make corrections to the shape of the material to obtain an aesthetically pleasing shape and typically do so without the use of tools or any specialized tools or equipment.
