Mesiodens, supernumerary teeth located between the upper permanent central incisors, are common, affecting 0.15%-1.9% of the population.

Report of the Case: A 6 year old male patient with deciduous dentition attended the pediatric dentistry postgraduate course at the Universidad Autonoma de Nuevo Leon for general evaluation. At the time of taking radiographs mesiodens were observed between 5.1 and 6.1. Diagnosis: Panoramic and periapical radiographs showed mesiodens near the floor of the nasal cavity. Treatment: Surgical approach by incision in the palatal area of the maxilla for the correct lifting of the flap in addition to the exodontia in dental organ 5.1, 6.1.

Results: After local anesthesia, incision was made to expose the mesiodens, using an elevator for its displacement and extraction, followed by silk suture.

Conclusion: Early identification and treatment of mesiodens are crucial to avoid future complications. This case highlights the importance of early diagnosis and accurate surgical intervention to ensure proper oral development and prevent potential problems.
