Tooth development can present changes and alterations in the shape, size, structure, and number of teeth. Among the quantity anomalies are supernumerary teeth, which develop in addition to the typical number of teeth. On the other hand, fusion is an anomaly of form that results from the union of two dental germs, which can be complete or incomplete depending on the stage of development. Dental fusion, which can result in double teeth or a split crown, is relatively common, with a prevalence of 0.1% to 2.5%; However, three-tooth fusion, known as "triple tooth," is a rare anomaly, with a prevalence of 0.02% in the primary dentition. We present the unusual case of a 5-year-old boy with a triple fusion in his primary dentition between two lower incisors and a supernumerary tooth.
