Odontomes are hamartomatous developmental malformation of dental tissues which causes disturbances in the eruption of teeth. In general, odontomes occur frequently in permanent dentition and are seldom associated with primary dentition. This case report presents an odontome attached with primary tooth which was incidentally found during routine radiographic diagnosis and it spotlights the significance of early diagnosis and management of odontome to prevent future complications such as retained deciduous teeth and impaction of permanent teeth, malocclusion, etc. How to cite this article: Kavitha M, Prathima GS, Kayalvizhi G, et al.
