Introduction: supernumerary teeth are dental development anomalies, also known as hyperdontia or extra teeth. Their prevalence ranges between 0.3% and 3.8%. Their morphology may be normal or dismorphic and are associated to the etiology of occlusal alterations. It is important to make an early diagnostic through a radiographical study.    Case presentation:this article presents a clinical case of a supernumerary tooth that caused rotation and crowding of the anterior bottom teeth, which was addressed properly by extracting the supernumerary tooth surgically and providing orthodontic treatment.   Discussion: to avoid complications and sequels in patients with supernumerary teeth, it is important to perform an early diagnostic with a proper radiographical evaluation.
