Nail biting, or onychophagia, often signals anxiety and ranges from a mild habit to a serious compulsion. It can damage nails, cause infections, and even lead to dental problems. Persistent nail biting may also affect self-esteem and social interactions. Treatment options include cognitive behavioral therapy, habit-reversal training, and stress management techniques. Stress balls, fidget toys, or bitter-tasting nail polish can help. Severe cases may require working with a mental health professional to address underlying causes.
