Mouth Damage from Nail Biting
Nail biting, while generally not considered dangerous, can have negative effects on the mouth. The human gut, soil, and water are home to a family of bacteria known as Enterobacteriaceae. Individuals who frequently bite their nails tend to have higher levels of these bacteria in their mouths. Moreover, the habit of nail biting can lead to damage to the gums and teeth. Apical root resorption, a condition where the gums start to reabsorb the teeth, is more common among those who regularly bite their nails. Furthermore, nail biting can also impact the temporomandibular joints of the jaw.
Finger Damage
Nail biting not only harms the mouth and gums, but it can also have negative effects on the fingers and nails. One of the potential consequences of nail biting is damage to the tissue surrounding the nails, which can result in infections. In more severe cases, individuals who frequently bite their nails may experience a condition known as disappearing nail bed, where the nail bed becomes significantly shortened or narrowed, giving the illusion of shorter nails. Surprisingly, nail biting can also lead to an increase in the growth rate of the nails.
