Key Takeaway
Note that endoscopic transnasal removal is the primary reported approach for managing intranasal teeth.

This narrative review synthesizes 170 patient records from 139 articles to describe the clinical presentation and management of intranasal teeth. The review highlights that 71.2% of cases involved supernumerary teeth and 79.4% involved the nasal floor. Imaging documentation was available in 97.6% of cases, with 68.8% utilizing CT, CBCT, or MSCT imaging.

Management findings indicate that removal or direct extraction was performed in 92.4% of the cases. The authors note that endoscopic transnasal removal is the predominant published approach for these cases. The review highlights that the majority of patients were male (63.3%) with a median age of 24.0 years.

Limitations include a lack of consistent reporting on adverse events and a lack of post-treatment outcome data. Because the evidence is based on case reports and narrative synthesis, it does not support comparative claims between different surgical approaches. Clinical management should be individualized based on patient symptoms, anatomical depth, and procedural risk.

Imagine feeling a constant blockage or a strange sensation in your nose that just won't go away. For some people, the cause is an unusual physical reality: an extra tooth growing inside the nasal passage. This condition, known as an intranasal tooth, can cause significant discomfort, including pain, nosebleeds, and a feeling of a foreign object stuck inside.

A review of 170 patient records highlights how these cases typically present. Most patients were around 24 years old, and about 63% were male. In many cases, these were supernumerary teeth, which are extra teeth that shouldn't be there. These teeth often involve the nasal floor and can lead to issues like runny noses or a buildup of mucus.

While the review notes that surgical removal is the most common way to treat these cases, the evidence is limited. Because the data comes from individual cases rather than a large controlled trial, we don't have much information on long-term outcomes or specific side effects. Doctors recommend that treatment be tailored to each person based on their specific symptoms and the location of the tooth.

What this means for you:
Extra teeth in the nasal passage can cause pain and blockage, usually requiring surgical removal based on individual needs.

Common questions

What symptoms do intranasal teeth cause?

People with extra teeth in their nasal passages may experience several issues. These include a feeling of a foreign object in the nose, nasal blockage, pain, nosebleeds, and a runny nose or discharge. Because these symptoms can be uncomfortable, doctors look at the specific location and depth of the tooth to decide on the best treatment.

Who is most commonly affected by this condition?

The data from 170 cases showed a median age of 24 years for patients. Among those recorded, 63.3% were male. The review also noted that about 71.2% of the cases involved supernumerary teeth, which are extra teeth that are not part of the normal dental structure.

How is an intranasal tooth typically treated?

The most common approach reported is endoscopic transnasal removal. However, because the evidence comes from a review of individual cases, doctors suggest that treatment should be individualized. They must consider the patient's specific symptoms, the depth of the tooth, and the risks involved before choosing a method.

Intranasal teeth are rare ectopic teeth situated wholly or partly within the nasal cavity. Because the evidence is dominated by case reports and terminology and anatomical boundaries vary across reports, diagnostic assessment and management have not been standardised. This review characterises the clinical presentation and synthesises patient-level evidence relevant to imaging, operative planning and multidisciplinary management. We conducted a structured narrative review of PubMed, Embase, Web of Science and Scopus, supplemented by citation searching. Reports were eligible when a tooth entered or projected into the nasal cavity; teeth confined to a paranasal sinus without nasal-cavity involvement were excluded from the dataset. The included reports were critically appraised using the appropriate JBI checklist for case reports or case series. The dataset comprised 139 articles and 170 patient records. Age was reported for 169 patients (median 24.0 years, range 1.67–78), and sex for 169, of whom 107 (63.3%) were male. Supernumerary teeth were reported in 121 records (71.2%), and nasal-floor involvement in 135 (79.4%). The most frequently reported manifestations were nasal obstruction (n = 94), rhinorrhoea or purulent discharge (n = 73), mass or foreign-body sensation (n = 50), epistaxis (n = 46), and pain (n = 44). Any imaging was documented in 166 records (97.6%), including CT, CBCT or MSCT in 117 (68.8%). Removal or direct extraction was performed in 157 records (92.4%). Critical appraisal identified limitations in adverse-event reporting and post-treatment outcome reporting. CT or CBCT interpreted with nasal endoscopy and oral examination provides the basis for confirming tooth identity, defining three-dimensional anatomy and selecting operative access. Endoscopic transnasal removal is the predominant published approach, whereas deeply embedded nasal-floor or nasal-maxillary-junction teeth may require oral or combined access. Management should be individualised according to symptoms, anatomical depth, procedural risk and the feasibility of surveillance. The case-based evidence does not support comparative claims between approaches.
