Nail biting can affect nail health. Nail biting can weaken the nails and make them more susceptible to infections. Try a product that hinders nail biting, or see your doctor for tips on how to stop biting your nails.

Nail biting can contribute to poor nail health. When you bite your nails, you may be introducing germs and bacteria from your mouth to the nail area, where they can cause infection. Nail biting can also break the skin around your nails and cause hang nails, which increases your chances of infection. Because children tend to bite their nails or suck their fingers or thumbs, they are particularly at risk for hang nails and infections such as paronychia, an inflammation of the skin on either side of the nail caused by nail biting.
