Oral mucosa
Swelling and redness of the oral mucous membranes may be a sign of an intolerance or allergy.
Tattoo-like markings in the oral mucosa suggest metal deposits. There is usually chronic bone inflammation beneath these markings. This may be painful or painless. Painful chronic inflammation of the jawbone is known as NICO (Neuralgia Inducing Cavitational Osteonecrosis). This condition causes non-specific nerve pain (neuralgia) in the head.
Mucosal changes (lichen) may also be a precursor for cancer of the mucous membranes.
