A 25-year-old female who presented with unilateral mandibular bone exostosis had her clinical diagnosis confirmed using cone beam computed tomography. Additionally, a nodular torus palatinus was found in the midline of the palate. Wear faces on the vestibular cusps of 46 as well as thickening of the periodontal ligament space were present. Both are signs of occlusal trauma. The presence of mandibular tori could indicate other underlying conditions, such as the presence of parafunctional activity or systemic health conditions. Mandibular exostosis can remain for life without the need to be surgically removed unless it compromises prosthetic rehabilitation.
