Hello. What you're describing is known as cheek biting - a type of body-focused repetitive behavior (BFRB). It’s commonly seen in individuals with anxiety disorders or obsessive-compulsive spectrum conditions. It often acts as a coping mechanism during stress or mental tension, and becomes a repetitive habit cycle.
Next Steps
Please consult a psychiatrist or clinical psychologist trained in CBT for BFRBs. Habit Reversal Training (HRT) is a specific technique proven helpful. Medications like SSRIs may also help reduce the urges when used alongside therapy.
Health Tips
Avoid guilt- this behavior is not your fault and is treatable. Keep a log of triggers and practice grounding techniques. Mouth guards or barrier methods can help prevent injury while behavioral strategies work to break the cycle.
