Supernumerary tooth (ST) or hyperdontia is a dental anomaly characterized by the presence of additional tooth to the normal series in either of the dentition. Mesiodens are 80% of all the supernumerary teeth with a ratio of 2:1 among the males and females. Supernumerary molars usually referred to as paramolar and distomolar, are small and rudimentary in size than the actual molar. paramolar is commonly situated in the location buccal or palatal to maxillary permanent molars while distomolars are located distal to the maxillary third molars. Occurrence of ST is 0.3% – 0.8% in deciduous dentition and 1.5% – 3.5% in permanent dentition as reported in the literature. Usually unerupted ST is asymptomatic and is accidentally found on radiograph. This is a case of distomolar with right erupted maxillary third molar causing recurrent ulceration and extreme distress to the patient.
