Oral tuberculosis (TB) is an extremely rare event in both phthisiatic and dental practice. The paper describes a clinical case of a patient who visited a dental clinic for acute pain. After tooth extraction, the patient was observed to have atypical clinical presentations. Histological examination revealed alveolar socket TB. Further examination diagnosed pulmonary TB in the patient. Dentists recommend that the duration of planned fluorography should be specified for patients. In addition, patients with pulmonary TB should undergo oral cavity sanation to reduce the risk of oral TB.
