Tuberculosis is a chronic granulomatous infectious disease caused by Mycobacterium tuberculosis and is a major health problem in most developing countries. It can affect any part of the body including the oral cavity, though extra pulmonary tuberculosis is rare, occurring in 10% to 15% of all cases. Oral tuber­culosis can be primary or secondary. Primary oral tuberculous lesions are extremely rare and generally occur in young adults. It usually involves gingival and is associated with caseation of the dependent lymph nodes; the lesion itself remains painless in most cases. In contrast, secondary oral tuberculosis is common and is usually seen in older adults. The most commonly affected site is the tongue, followed by palate, lips, buccal mucosa, gin­giva, and frenulum. Tuberculous lesions may present as superficial ulcers, patches, indurated soft tissue lesions, or even lesions within the jaw in form of osteomyelitis
