Morsicatio buccarum

Morsicatio buccarum is a condition marked by chronic irritation or injury to the buccal mucosa, the lining of the inside of the cheek within the mouth. The cause is repetitive behaviour: the affected person habitually chews, bites or nibbles at the tissue of the cheek, and the repeated minor trauma is what produces the change in the lining. The source lead defines the condition in a single sentence and does not describe its appearance, frequency, diagnosis or management, so this entry records only what that lead supports and leaves further detail to later depth work. This entry is a record of the condition, not medical advice.
