  1. Gum Diseases, Tooth Root Damage, and Jaw Joint Dysfunction: Nail-biting can lead to gum diseases and damage to tooth roots due to the constant manipulation of teeth and nails in the mouth. It may also contribute to dysfunction in the jaw joint.
  2. Deterioration of Nail Structure and Nail Infections: Nail-biting can adversely affect the structure of the nails, causing weakness, cracks, and breakage. Additionally, it may lead to the development of infections in the nails.
  3. Lack of Hand Hygiene and Intestinal Infections: The habit of nail-biting, coupled with insufficient hand washing or hygiene, can result in the transfer of bacteria and microbes from the nails to the body through the mouth. This can contribute to the development of intestinal infections.
  4. Feelings of Shame and Guilt: Nail-biting can lead to the development of feelings such as shame and guilt in individuals. These emotions can negatively impact a person’s mental well-being.

Nail-biting behavior is generally a behavior that emerges in childhood. Some parental attitudes can lead to the emergence of this behavior. Authoritarian parental attitudes, communication problems within the family, arguments between parents, scolding by parents, neglect, and lack of affection can create situations that lead to nail-biting behavior.

“Various emotions such as aggression, anger, distress, sadness, anxiety, fear, worthlessness, and insecurity are claimed to pave the way for nail-biting disorder. For this reason, some researchers suggest that nail-biting behavior has an anxiety-reducing effect, and that’s why the behavior is repeated.”
