A tooth presenting in the nasal cavity is an unusual phenomenon. Supernumerary teeth usually occur in the upper incisor area. Other locations may be the maxillary third molar and the mandibular bicuspid areas. Nasal teeth are a rare form of supernumerary teeth. They may be asymptomatic or may present with nasal obstruction and infection. They may be removed through a nasal approach.
牙齿出现在鼻腔内是一种不寻常的现象。多生牙通常发生在上颌切牙区。其他部位可能是上颌第三磨牙和下颌双尖牙区。鼻内牙是多生牙的一种罕见形式。它们可能没有症状，也可能表现为鼻塞和感染。可以通过鼻腔途径将其拔除。
