Onychophagia, another name for nail biting, is the unhealthy practice of biting one's own fingernails or toenails. It is a typical anxious behavior that can last into age and usually starts in infancy or adolescence. The actions frequently take place unintentionally when under stress, worry, boredom, or inaction. In addition to causing discomfort, bleeding, infections, and an ugly appearance, nail biting can also harm the cuticles, surrounding skin, and nails themselves. A long-term habit of chewing your nails can potentially harm your teeth, jaw, and oral health. It frequently takes a mix of awareness, self-control, relaxation techniques, and professional assistance, as needed, to break the habit.
