cheekchewing

Cheek chewing, also known as morsicatio buccarum, is a common habit characterized by the repetitive biting or gnawing of the inner cheek tissue. It is considered a body-focused repetitive behavior (BFRB) and is often grouped with other behaviors such as nail biting and skin picking. This behavior can occur unconsciously, particularly during periods of stress, anxiety, boredom, or concentration. While some individuals may engage in mild cheek chewing, for others it can become a more persistent and compulsive habit.

The causes of cheek chewing are not fully understood, but it is believed to be influenced by a combination of psychological and physiological factors. It may serve as a self-soothing mechanism, providing a sense of comfort or distraction from uncomfortable emotions. In some cases, it can develop as a learned behavior or be triggered by specific environmental cues. While often considered benign, chronic or severe cheek chewing can lead to physical consequences.

These physical effects may include irritation, inflammation, and soreness of the inner cheek lining. In more extreme instances, persistent chewing can result in the formation of small lumps or ulcers on the affected tissue, which may become painful and interfere with eating or speaking. While generally not a cause for significant medical concern, persistent and bothersome cheek chewing can sometimes be associated with underlying anxiety or stress disorders, and individuals experiencing significant distress or physical discomfort may benefit from consulting a healthcare professional. Treatment often focuses on identifying and managing triggers, developing alternative coping strategies, and, in some cases, behavioral therapies.
