Several cases of the ectopic supernumerary tooth in the nasal cavity have been reported; however, an eruption of the primary maxillary tooth in the nose following trauma is extremely rare. Clinical evaluation and discriminating features on CT imaging, particularly with bone window setting, are sufficient to confirm the diagnosis. We discuss a case of deciduous central maxillary incisor in the nasal cavity and specifically focus on its clinical and radiological presentation. None of the previous authors have discussed probable theories of the post-traumatic intranasal tooth; we consider two possible theories which might be responsible for the ectopic intranasal tooth after trauma. Additionally, we discuss pertinent features which help distinguish ectopic deciduous tooth from the supernumerary tooth.
