Mesiodens are common supernumerary teeth that prominently erupt in the midline between the maxillary central incisors. If two or more mesiodens are present, they are termed mesiodentes, indicating the presence of multiple supernumerary teeth in the midline. These often cause aesthetic disharmony in the anterior teeth due to their abnormal position, leading to extraction in most cases and resulting in midline diastema when impacted or partially erupted. This case is uncommon, as the patient expressed a desire to preserve their mesiodens as a distinctive feature, considering them a familial trait worth retaining. The family history of the patient revealed the occurrence of mesiodens in three generations, highlighting a hereditary pattern of supernumerary teeth within the family. The endodontic therapy involving root canal treatment successfully treated the mesiodens, alleviating pain, and preserving them as desired.
