Nail biting, medically known as onychophagia is a common habit beginning in childhood and may continue into adulthood.People usually bite their nails when they are nervous, stressed, hungry or bored. This, however, can sometimes be a sign of an emotional or mental problem, especially if it continues to uncontrollable levels.That said, a few people trim their nails by biting them but unfortunately, this may turn into a habit that is continued into adulthood. Since fingernails protect the fingertips, bitten off irregularly apart from the nails getting deformed can lead to pain and saliva may soften the fingertips, leading to infections.Also, fingernail biting can transmit intestinal parasites besides causing cosmetic problems because it may deform fingernails with the victim getting embarrassed and always trying to hide the fingers.The problem can be discouraged by applying nail creams or polishes that do not smell or even taste nice.If this fails to help, then counseling one out of the habit may be required.
