K13: Other diseases of lip and oral mucosa
K13.1: Cheek and lip biting
Cheek and lip biting is a condition wherein the individual is compelled to bite or chew on the inside of their cheeks or lips. It's typically an unconscious habit often linked with stress, anxiety, or nervousness, but can occur absent of these elements, especially during sleep or intense concentration. The condition often results in the appearance of small, often painful, ulcers or sores on the inner cheek or lip. Continuous biting or chewing in the same spot can lead to thickened skin or scar tissue. Over time, this condition can disrupt daily life due to the discomfort and irritation caused, especially when talking, eating or sleeping. This condition most commonly involves the oral and digestive system, primarily affecting the mouth's mucous membranes.
