By: Suzanne Feinstein, PhD

It may come as a surprise that nearly 30% of individuals engage in nail-biting. If you find yourself grappling with this habit, rest assured that you are not alone.

There are numerous factors that drive individuals to bite their nails. The good news is that it is possible to overcome this habit.

Potential Causes of Nail-Biting?

Stress and anxiety are primary contributors. Individuals often resort to nail-biting as a coping mechanism in stressful situations.

Feelings of boredom or impatience can also trigger this habit by serving as a mindless activity to occupy idle moments. Perfectionism can further fuel nail-biting, acting as a subconscious response to self-regulate difficult emotions.

Childhood experiences frequently shape this behavior, with nail-biting typically starting during early developmental stages. Understanding the multifaceted causes of nail biting is essential for developing targeted strategies to curb the habit, thereby fostering healthier alternatives for managing emotions and stressors.

Who Is Prone to Nail-Biting?

Nail biting is a habit that can manifest across all age groups, but it predominantly starts during childhood. Children may adopt nail-biting due to:

  • A response to stressors
  • Feelings of impatience or boredom
  • Imitation of observed behaviors

While some individuals outgrow this habit, others carry it into adolescence and adulthood. The persistence of nail biting is influenced by various factors, including genetic predispositions and environmental influences.

Research suggests that individuals with Attention Deficit Hyperactivity Disorder (ADHD) may also be more susceptible to nail-biting due to the impulsive tendencies often associated with ADHD.

Nail-Biting Treatment (Habit Reversal/ Stimulus Control Techniques)

Overcoming the nail-biting habit requires a multi-faceted approach. Here are some effective strategies to help curb the urge to bite your nails:

Habit Reversal Techniques

One effective method to combat nail-biting is through habit reversal techniques. By heightening the awareness of the trigger that leads to nail biting, one can substitute this unwanted behavior with a more adaptive and healthy one.

If the habit is stress-induced, consider substituting the behavior with deep breathing exercises or other stress-relieving techniques. If the behavior stems more from mindlessness, changing location and activity can be an effective way to break the emotionally detached state and wake up the senses. 

Stimulus Control Techniques

Stimulus control techniques aim to modify the environment to decrease the likelihood of nail-biting. This could involve maintaining short nails to reduce the opportunity for biting. Utilizing bitter-tasting nail coatings or wearing gloves can also act as deterrents.

Keep Your Nails Short

Maintaining shorter nails reduces the surface area available for biting and diminishes the physical sensation associated with nail-biting.

Use Bitter-Tasting Nail Coatings

Consider applying a bitter-tasting nail coating as a deterrent. These specialized coatings, available at most drugstores, create an unpleasant taste, rendering nail biting less appealing.

Identify Triggers

Stay attuned to situations or emotions that compel you to bite your nails. Whether it’s stress, boredom, or impatience, identifying the root cause aids in finding alternative coping mechanisms.

Keep Your Hands Busy

Engage your hands in activities that discourage nail biting. Consider using a fidget spinner, stress ball, or other handheld gadgets to divert nervous energy away from your nails.

Wear Gloves

If you find it challenging to curb the nail-biting habit, consider wearing gloves, particularly in situations where you’re more prone to bite your nails. This physical barrier can serve as a reminder and make it more difficult to engage in the behavior.

Reward Yourself

Establish a reward system for abstaining from nail biting. Set achievable goals and reward yourself when you reach milestones. Positive reinforcement can bolster your commitment to overcoming the nail-biting habit.

Seek Support

Seeking support from others can provide encouragement and understanding when you’re tempted to bite. Other people can also help keep you accountable and remind you of your commitment if they see you fighting the urge to bite.

Maintaining Oral Hygiene

Improve your oral hygiene routine to make your nails less appealing. Regular tooth brushing, using mouthwash, and maintaining clean nails are recommended. The fresher your mouth feels, the less inclined you will be to engage in nail biting.

Seeking Professional Help

Have self-help strategies proven inadequate? Professional help is worth considering. Behavioral therapy can provide structured interventions to tackle the root causes of nail biting.

Is your nail biting habit linked to an underlying psychological condition, such as anxiety or ADHD? Consultation with a medical professional or therapist could be beneficial.

Remember, overcoming the nail-biting habit is a gradual process that requires patience and persistence. Employing a combination of these strategies can increase your likelihood of success and foster healthier nail care habits over time.

The Side Effects and Risks of Nail-Biting 

Contrary to what some people believe, nail biting can be harmful. It can lead to several physical and psychological side effects and risks.

Physical Complications

Biting your nails can introduce harmful bacteria from your fingers into your mouth, potentially leading to nail infections. Chronic nail biting can also result in chips or cracks in your teeth and may even contribute to jaw complications.

Psychological Complications

The appearance of bitten nails can lead to feelings of embarrassment and shame, thereby impacting an individual’s self-esteem. Nail biting could also be indicative of underlying mental health issues. Failing to address this could exacerbate your mental well-being over time.

When to Seek Professional Help

If nail biting becomes a persistent and uncontrollable habit, or if it results in physical or psychological complications, it is important to seek professional help. Here are some indicators that it may be time to consult a healthcare provider or therapist:

  • Inability to cease: Despite attempting self-help strategies, nail-biting persists
  • Interference with daily life: Nail biting begins to affect daily activities, relationships, or work
  • Signs of infection: The nail-biting habit is severe enough to compromise the health of your nails
