Nail biting is a common habit, especially among children. While it might seem harmless, it can have significant impacts on dental health. Pediatric dentists often see the consequences of this habit in young patients. Understanding the effects of nail biting and how to prevent them can help parents protect their children’s smiles.

Why Do Kids Bite Their Nails?

Nail biting, or onychophagia, usually starts in childhood. Children might bite their nails because of stress, boredom, or even mimicry. It’s a way for them to cope with anxiety or simply keep themselves occupied. However, what starts as a simple habit can lead to serious dental issues.

Dental Health Risks

  1. Tooth Damage: Constant nail biting puts pressure on the teeth, especially the front ones. This can cause the teeth to chip, crack, or wear down over time. For children with developing teeth, this habit can lead to misalignment and the need for orthodontic treatment later.
  2. Braces Complications: If a child already has braces, nail biting can be particularly harmful. The habit can damage the braces, leading to longer treatment times and additional costs. It’s crucial to address this behavior early to avoid complications.
  3. Gum Infections: Fingernails harbor bacteria and dirt. Biting nails introduces these pathogens into the mouth, increasing the risk of gum infections. This can lead to gingivitis or more severe periodontal issues if not treated promptly.
  4. Nail biting can cause root resorption, where the body absorbs the root of a tooth in severe cases. This can lead to tooth loss if left unchecked.

Preventing Nail Biting

Addressing nail biting involves a multi-faceted approach. Here are some strategies to help curb this habit:

  1. Behavioral Techniques: Encourage children to replace nail biting with healthier habits, like squeezing a stress ball or chewing sugar-free gum. Positive reinforcement and setting achievable goals can also be effective.
  2. Nail Treatments: Applying bitter-tasting nail polish can deter children from biting their nails. These products are safe and can significantly reduce the incidence of nail biting.
  3. Professional Guidance: Consulting with a pediatric dentist can provide valuable insights and tailored advice. Pediatric dentists can recommend specific interventions and monitor the child’s dental health to prevent long-term damage.

Importance of Regular Dental Visits

Educating Your Child

Educating your child about the negative effects of nail biting can also help. Use simple terms to explain how nail biting can hurt their teeth and gums. Providing information empowers them to make better choices for their dental health.

Creating a Supportive Environment

Creating a supportive environment at home can make a big difference. Encourage your child and praise their efforts to stop nail biting. Offer small rewards for progress and be patient with setbacks. Consistency and support are key to breaking the habit.


Nail biting is more than a minor habit; it can have serious implications for dental health. By understanding the risks and implementing preventive measures, parents can help their children maintain healthy teeth and gums.
