Nail Biting

Nail biting, or onychophagia, is a common compulsive habit affecting up to one third of children and many adolescents before declining in adulthood. It often occurs during times of stress, boredom or anxiety, serving as a coping mechanism for managing tension or mental focus.

Health & Cosmetic Concerns:

• Damages nails and cuticles, leading to ragged edges, bleeding, hangnails or infections such as paronychia.
• May harm oral health, causing gingival injury, jaw (TMJ) pain, or tooth misalignment from habitual chewing.
• Introduces germs and dirt into the mouth, increasing risk of infections and swallowing bacteria-laden particles.
• Can also lead to psychological and social distress such as embarrassment or reduced self-esteem.

How to Stop Nail Biting:
Track when and what triggers you to bite your nails. It maybe boredom, concentration or tension. Try to replace nail biting with alternative actions like chewing gum, using stress balls, or fidget tools to keep hands and mouth busy. Remove nail irregularities with filing and use a bitter nail deterrent polish. Products like Stop 'n Grow liquid deterrents are available for this purpose.

Nail biting is more than just a bad habit - it is often a reaction to stress or tension with real health and cosmetic impacts. However, it can be successfully managed and overcome with substitute behaviours, bitter deterrents, good nail care and supportive strategies.
