What You'll Learn

Anxiety
Nail biting is a common behaviour in children, with about half biting their nails at some point during childhood. It is a difficult behaviour to modify or treat, and many children who try to stop are unsuccessful.
Nail biting can be a sign of anxiety in children. Kimberly Montez, MD, MPH, assistant professor of pediatrics at Wake Forest School of Medicine, says that because nail biting is a repetitive habit, it may be a self-soothing behaviour. Dr Chavis agrees, saying that if a child is experiencing pain or discomfort from nail biting but continues to do it, they may be trying to relieve anxiety.
Children bite their nails for different reasons, and anxiety is not the only cause. Boredom or restlessness can also be triggers, as nail biting provides sensory feedback that some children crave.
Nail biting can have negative consequences for dental hygiene and health, and children may be self-conscious about their habit.

Boredom or restlessness
Nail biting is a common habit in children, with about half of kids biting their nails at some point. Kimberly Montez, MD, MPH, assistant professor of pediatrics at Wake Forest School of Medicine, says that nail biting can be a self-soothing behaviour for children who are anxious.
However, boredom or restlessness can also be a trigger for nail biting. Some children have trouble sitting still or paying attention for long stretches, and nail biting provides a quiet physical activity and sensory feedback that they crave.
Nail biting can be a difficult behaviour to modify or treat. Many children with this habit have already tried to stop it but have been unsuccessful. This can cause frustration for the child and those around them, such as parents and siblings.
If your child is experiencing pain or discomfort from nail biting but continues to do it, they may be trying to relieve underlying anxiety. In this case, it is important to seek professional help to address the underlying cause.

Dental hygiene
Nail biting is a common behaviour in children, with about half of kids biting their nails at some point during childhood. It can be a sign of anxiety, boredom or restlessness. It can also cause dental issues, such as gum and tooth root damage.
Good dental hygiene is important for overall health and can help prevent issues such as gum disease and tooth decay. Here are some tips to help your child maintain good dental hygiene:
- Brush twice a day: It is important to brush teeth twice a day, once in the morning and once before bed. Use a soft-bristled toothbrush and fluoride toothpaste. Teach your child to brush gently in circular motions, covering all surfaces of the teeth and gums.
- Floss daily: Flossing is essential for removing plaque and food particles from between the teeth. Show your child how to floss correctly, using a gentle sawing motion.
- Limit sugary snacks: Sugar is one of the main causes of tooth decay. Limit sugary snacks and drinks, and encourage your child to eat healthy snacks such as fruits and vegetables, which are high in fibre and help to clean the teeth.
- Visit the dentist regularly: Regular dental check-ups are important for maintaining good dental hygiene. Take your child to the dentist every six months for a check-up and cleaning.
- Set a good example: Children learn by imitation, so it's important to set a good example by practising good dental hygiene yourself. Brush and floss your teeth regularly and make it a family routine.
By following these tips, you can help your child develop good dental hygiene habits that will benefit them for a lifetime.

Co-morbid psychiatric disorders
Nail biting is a common behaviour in children, with about half of kids biting their nails at some point during childhood. While it may seem like a simple habit that can be stopped easily, many children with nail-biting habits have already tried to stop and have been unsuccessful. This can lead to frustration for the child and their family members. Research suggests that co-morbidities of psychiatric disorders and other stereotypic behaviours in clinical samples of children with nail-biting are more than 80%.
Nail biting can be a sign of underlying anxiety or depression. It may be a self-soothing behaviour for children who are experiencing anxiety or stress. The repetitive action of nail biting can provide sensory feedback that some children crave, especially if they have trouble sitting still or paying attention for long periods.
In some cases, nail biting can be a way for children to cope with pain or discomfort. Dr. Chavis explains that if a child continues to bite their nails despite experiencing pain, it may be an indication that they are trying to manage underlying anxiety or stress.
The impact of nail biting on dental hygiene and physical appearance should also be considered. Research shows that nail biting can contribute to gum and tooth root damage, and people who bite their nails tend to have poorer dental hygiene. Additionally, children may feel self-conscious about their nail-biting habit, especially if their hands are often in their mouths or their fingernails look ragged.
Overall, while nail biting is a common behaviour in children, it can be a sign of underlying psychiatric disorders or other co-morbidities. It is important to address nail-biting habits and provide support for children who may be struggling with anxiety, depression, or other mental health concerns.
