Tooth gemination, also known as schizodontia, twinning, or double teeth, occurs when a single tooth germ splits during development.^[1] Splitting of the tooth may be partial or complete. If the splitting is complete, the extra tooth is known as a supernumerary tooth.^[2] Tooth gemination is difficult to distinguish from tooth fusion, thus, both conditions are often referred to as “double teeth”.^[1]

Double teeth can cause other dental problems such as crowding, ectopic eruption of adjacent teeth, gum issues, cavities, malocclusion, poor esthetics, and more.^[1] Treatment depends on whether the tooth is primary or permanent, the degree of splitting, and its functional & esthetic impact.^[2]
