Over time, what started as an occasional reaction can turn into a pattern that is difficult to control. Some people even say they only realize they are biting their nails when the damage is already done. This loss of control is one of the signs that the behavior is worth paying attention to.
Beyond the aesthetic aspect, onychophagia can have physical consequences. Constant nail biting can cause inflammation of the skin around the nail, can promote infections such as paronychia , can generate pain and disrupt normal nail growth. In some cases, deformities, recurring small wounds or light bleeding are observed. In addition, frequent contact between hands and mouth increases the risk of transmitting microorganisms, especially if there are open wounds.
Dental complications can also occur. Repeated pressure on the teeth can contribute to enamel wear or minor bite problems. While this doesn’t always happen, it’s something that health professionals consider when the habit persists.
