Nail biting, or onychophagia, is a common habit that often begins in childhood. While it may not cause any long-term damage, chronic nail-biting can lead to abnormal-looking nails and other issues. This is because nail biting can damage the tissue that makes nails grow, resulting in deformed nails. Additionally, it can cause soreness and vulnerability to infections as harmful bacteria and viruses are transferred from the mouth to the fingers and vice versa.

What You'll Learn
Nail biting can cause abnormal nail growth
Nail biting, or onychophagia, is a common problem that often starts in childhood and can continue into adulthood. While nail biting typically doesn't cause any long-term damage, it can lead to abnormal nail growth and other issues. Repeated nail biting can damage the tissue around the nails, resulting in abnormal-looking nails. This can include deformed or misshapen nails that no longer grow as they should.
Chronic nail biting can also cause soreness and vulnerability to infection. The skin around the nails may become tender and irritated, and the constant biting can transfer harmful bacteria and viruses from the mouth to the fingers and face. Additionally, nails can become a haven for germs, increasing the likelihood of getting sick.
To address abnormal nail growth and break the nail-biting habit, it is important to identify the triggers. Stress, anxiety, boredom, and frustration are common factors that lead to nail biting. By understanding these triggers, individuals can develop strategies to manage them effectively. This may include keeping the hands busy with fidget devices, stress balls, or silly putty, or finding alternative oral stimuli such as chewing gum.
Trimming nails short and maintaining a regular manicure can also deter nail biting. Short nails provide less temptation to bite, and the investment in a manicure may serve as an incentive to avoid biting. Applying bitter-tasting nail polish is another effective tactic to discourage nail biting. These products are safe and leave an unpleasant taste that reduces the desire to bite.
In more severe or persistent cases, individuals may benefit from cognitive behavioral therapy (CBT) or acceptance and commitment therapy (ACT). These therapeutic approaches can help address the underlying psychological factors contributing to the nail-biting habit and support the development of healthier coping mechanisms.

It can lead to dental issues
Nail biting, or onychophagia, is a common habit that often begins in childhood and can continue into adulthood. While it may not cause any long-term damage to your fingers, it is unsanitary and can lead to various dental issues.
Dental Issues Associated with Nail Biting
Nail biting can have several negative impacts on oral health. Firstly, it can lead to the erosion, chipping, and cracking of teeth. The grinding friction of teeth against nails can gradually wear down the tooth enamel, leaving teeth vulnerable to chipping and cracking. This can result in significant pain and further dental complications. Additionally, nail biting can cause malocclusion, or problems with the bite, and gaps between teeth as the constant pressure can cause teeth to shift and move.
Another serious consequence of nail biting is root resorption, where the jaw bone reabsorbs the roots of the teeth, weakening them and increasing the risk of tooth loss, especially for individuals with braces. Nail biters are also at a higher risk of developing bruxism, or teeth grinding, which is associated with oral health problems, headaches, and facial pain.
Furthermore, nail biting can contribute to gum disease, or gingivitis, as bacteria and germs trapped under the fingernails are transferred to the mouth. This can also lead to gastrointestinal infections if harmful bacteria, such as E. coli and salmonella, are ingested. Paronychia, an infection of the fingertips, can also develop, causing redness, swelling, and pus that may require surgical drainage.
Prevention and Treatment
To prevent dental issues caused by nail biting, it is crucial to break the habit. This can be challenging, but several strategies can help. Keeping nails trimmed short reduces the temptation to bite them. Applying bitter-tasting nail polish is also effective, as it associates nail biting with an unpleasant taste. Manicures can be a deterrent, as people are less likely to bite their nails if they look well-groomed. Identifying triggers, such as boredom or anxiety, can help develop strategies to avoid or manage these situations. For some, cognitive behavioral therapy (CBT) or acceptance and commitment therapy (ACT) may be beneficial in addressing the underlying psychological aspects of nail biting.

It increases the risk of infection
Nail biting is a common habit, with up to 30% of the population doing it. However, chronic nail biting can have several negative consequences, one of which is an increased risk of infection.
Firstly, nail biting can cause bacterial infections of the nail, known as paronychia. Paronychia is an inflammation of the skin around the nail, caused by bacteria or fungi. Acute paronychia is usually bacterial and caused by the bacterium Staphylococcus aureus, while chronic paronychia is typically caused by a yeast infection of the soft tissues around the nail. However, both types of paronychia can be caused by nail biting, as biting can create cuts or broken skin that allow bacteria to enter. Symptoms of paronychia include pain, swelling, and redness around the nail, as well as pus buildup under the skin. In some cases, an abscess may form and require drainage. Paronychia is treated with antibiotics for bacterial infections and antifungals for fungal infections.
Additionally, nail biting can increase the risk of ingesting harmful bacteria, which can lead to stomach or intestinal infections. Furthermore, nail biting can cause dental problems, such as misalignment and chipped teeth, which may further increase the risk of infection by providing additional entry points for bacteria.
To reduce the risk of infection associated with nail biting, it is important to break the habit. This can be challenging, as nail biting is often a coping mechanism for stress, boredom, or anxiety. However, there are several strategies that can help, including keeping nails trimmed short, applying bitter-tasting nail polish, and finding alternative behaviours to substitute for nail biting, such as squeezing a stress ball or chewing gum. In more difficult cases, cognitive behavioural therapy (CBT) and acceptance and commitment therapy (ACT) can be effective in addressing the underlying psychological causes of the habit.

It can be a sign of underlying mental health issues
Nail biting, or onychophagia, typically begins in childhood and can continue through adulthood. While it may not always cause long-term damage to nails, chronic nail biting can cause soreness and damage to the tissue that makes nails grow, resulting in abnormal-looking nails.
However, beyond the cosmetic impact, nail biting can be a sign of underlying mental health issues. It is considered the most common stress-relieving habit, with individuals reporting that they bite their nails when feeling nervous, bored, lonely, understimulated, or even hungry. Nail biting can also be a habit transferred from earlier thumb or finger sucking. While it can occur without symptoms of another psychiatric condition, it has been associated with attention-deficit/hyperactive disorder (ADHD), oppositional defiant disorder, separation anxiety, enuresis, tic disorder, and other mental health issues.
Nail biting shares neurological roots with OCD, anxiety, and other mental health disorders, and it is often classified as a body-focused repetitive behaviour (BFRB) related to obsessive-compulsive disorders. People with a BFRB who bite their nails may also engage in other body-focused repetitive behaviours such as skin picking and hair pulling, known as pathological grooming. This behaviour can be rewarding and stimulating, and some individuals may find it challenging to break the habit.
If nail biting is causing distress or impacting your life, it may be beneficial to seek professional help. Cognitive behavioural therapy (CBT) and acceptance and commitment therapy (ACT) can address the psychological aspects of nail biting. Behaviour therapy and habit-reversal training may also be effective in managing this habit.

Strategies to stop biting your nails
Long-term nail-biting can change how your fingers look, as it can damage the tissue that makes nails grow, resulting in abnormal-looking nails. Chronic nail biting can also lead to dental problems such as misalignment and chipped teeth. It can also cause jaw problems over time.
Identify your triggers
Noticing how you feel or what you're doing when you bite your nails can help you find other ways to cope. Nail biting is often triggered by boredom, stress, or anxiety. By figuring out what causes you to bite your nails, you can work on avoiding these situations and develop a plan to stop.
Keep your hands and mouth busy
Try to replace the nail-biting habit with a healthier one. You can fiddle with a stress ball, a worry stone, or even a pen to click. Chewing gum can also help keep your mouth occupied.
Keep your nails trimmed and maintained
Keeping your nails short and well-maintained can help reduce the temptation to bite them. This includes cutting your nails straight and around the tips to avoid snagging them. Pushing your cuticles back can also help.
Apply bitter-tasting nail polish
Using a bitter-flavored varnish on your nails can act as a deterrent. When you absentmindedly try to bite your nails, the nasty taste will remind you to avoid repeating the behavior.
Gradually break the habit
Instead of going cold turkey, set small goals for yourself. Try to stop biting the nails on one hand first, and then gradually include the other hand. The goal is to eventually stop biting any of your nails.
Seek professional help if needed
If you've tried to quit on your own without success, consider seeking professional help. Cognitive behavioral therapy (CBT) and acceptance and commitment therapy (ACT) can help address the psychological aspects of nail biting. Behavior therapy can also be an option to explore.
