Abstract
Onychophagia is an habit of biting one’s nails and finger tips. It is also called nail biting (NB). It is a stress relieving oral habit adopted by many children and adults. People usually do it when they are nervous, stressed, hungry or bored. All the above situations are having a common phenomenon between them which is anxiety. Here, we present a case of onychophagia (NB), who had psychiatric comorbidity. Onychophagia cannot be managed without considering some related factors such as comorbidities, precedent and consequences of the behavior. The best way to treat a nail biter is to educate them, encourage good habits and should provide emotional support and encouragement. Behavior modification therapy has proved to be a successful means of treatment along with drug management.

Key words: onychophagia, nail biting, multidisciplinary approach, psychiatric comorbidity
