What You'll Learn
Nail biting is a self-soothing behaviour
Nail biting, or onychophagia, is a common habit that often starts in childhood. It is usually a comforting behaviour that people engage in when they are feeling nervous, bored, lonely, or even hungry. The act of chewing on nails reportedly relieves stress, tension, or boredom, and thus serves as a form of self-soothing. While it can occur without any underlying psychiatric condition, nail biting is frequently associated with anxiety and other mental health issues.
People who bite their nails often experience different triggers, such as anxiety, stress, boredom, or being mentally engrossed in another activity. It is classified in the DSM-5 as a "body-focused repetitive behaviour disorder", which falls under "Other Specified Obsessive-Compulsive and Related Disorders". Identifying these triggers and establishing replacement behaviours is crucial for effective treatment. Old-fashioned remedies, such as applying bitter-tasting products to nails, can be effective for some nail biters, especially those with less severe habits. However, for persistent and compulsive onychophagia, barrier-type interventions like gloves or mittens that block contact between the mouth and nails may be more successful.
The habit of nail biting can lead to several physical complications. It can cause soreness and cuts in the nails and surrounding skin, providing an entry point for bacteria and microorganisms, which can result in infections such as paronychia. Additionally, nail biters may experience tooth damage, including chipped teeth and erosion of tooth enamel, which can lead to oral health problems like gingivitis and bruxism (chronic teeth grinding). Ingrown nails are another potential complication, which can be very painful and may require immediate treatment to prevent worsening symptoms and serious infection.
While mild nail biting may not require medical treatment, it is important to address the underlying causes and manage any associated mental health issues. Cognitive behavioural therapy (CBT) can be an effective approach, helping individuals identify unhelpful behaviour patterns and replace them with healthier coping strategies. Additionally, keeping nails trimmed and maintaining proper hand and nail hygiene can help minimise the temptation to bite nails.
Breaking the habit of nail biting can be challenging, but with persistence and the right techniques, it is possible to succeed. Identifying alternative ways to self-soothe is essential, such as practising a "gentle touch" technique or using fidget devices, stress balls, or silly putty to keep hands occupied. Regular manicures and the use of special nail polishes with a bitter taste can also serve as deterrents. Seeking professional help from a mental health provider or a dermatologist can be beneficial for those struggling to quit nail biting.

It can lead to dental issues
Nail biting, or onychophagia, is a common habit that can have several negative consequences for dental health. While it is possible for serious or long-term damage to result from nail-biting, it is rare. However, there are several dental issues that can be caused by this behaviour.
One of the most common dental issues associated with nail biting is tooth damage. The friction between the teeth and nails can cause teeth to chip, crack, or break. This can lead to the need for corrective care, such as braces or retainers, to realign the teeth and jaw. In addition, tooth enamel can splinter or erode over time, leaving teeth vulnerable to decay and other issues. This can also lead to other oral health problems, including gum disease and gum recession, as the protective enamel is no longer intact. Furthermore, nail-biting can increase the likelihood of developing bruxism, a chronic teeth-grinding habit that can result in headaches, jaw soreness, and TMJ syndrome.
Nail biting can also introduce bacteria into the mouth, which can lead to gum infections and other dental issues. The nails and surrounding skin are hotspots for collecting germs, and when bitten, these bacteria can enter the mouth and cause infections. This can result in conditions such as gingivitis and paronychia, a type of nail infection that can cause redness, pus buildup, tenderness, and warmth in the affected area. If left untreated, paronychia can cause serious damage to the nail and underlying bone, and in severe cases, may even require the removal of the affected finger or toe to prevent further spreading of the infection.
In addition to these physical consequences, nail biting can also lead to social and emotional issues. Those who bite their nails may experience distress, emotional tension, or social embarrassment due to the negative impact on their dental health. This can further contribute to a negative cycle of increased nail-biting as a coping mechanism.
While the specific causes of nail-biting are not fully understood, it is often associated with anxiety and stress. Breaking this habit can be challenging, but there are several strategies that can help, including cognitive behavioural therapy (CBT), identifying triggers and replacement behaviours, and barrier-type interventions such as gloves or bitter-tasting nail coatings.

It can cause infections
Nail biting is a common habit, but it can have several negative consequences, including an increased risk of infections.
Firstly, nail biting can cause breaks and cuts in the skin around the nail, which may be painful. Open skin is an entry point for microorganisms, and if bacteria get in, it could lead to a staph infection. In some cases, this may be mild, but it can also form an abscess that requires oral antibiotics and drainage. Nail biting can also increase the risk of viral infections, and people who bite their nails often develop warts around and under their nails, which are challenging to treat due to the sensitivity of the skin in this area.
Secondly, nail biting can cause infections in the nail itself, known as paronychia. This occurs when bacteria enter broken skin near the cuticle, leading to symptoms such as reddening, pus buildup, tenderness, and warmth in the infected area. If left untreated, paronychia can cause damage to the nail, and in severe cases, the infection may spread to the underlying bone or finger, potentially requiring the removal of the infected nail to prevent further spread.
Thirdly, nail biting can lead to stomach and intestinal infections, especially if the bitten-off nails are swallowed. This habit can introduce harmful bacteria and germs into the digestive system, increasing the risk of infections in these areas.
Finally, nail biting can also increase the risk of fungal infections, particularly if proper hygiene and sterilization techniques are not followed during manicures or when using nail-biting prevention products such as bitter-tasting polishes. These infections can affect the nail plate (onychomycosis) and the surrounding skin (paronychia).
To minimize the risk of infections and other health complications, it is essential to address the nail-biting habit and practice good hand and nail hygiene. This may include keeping nails trimmed and maintaining overall hand and nail cleanliness.

It is classified as a body-focused repetitive behaviour
Nail biting, or onychophagia, is classified as a body-focused repetitive behaviour (BFRB). It is a common habit, often beginning in childhood, that can be challenging to stop. While it is not always indicative of an underlying disorder, chronic nail biting can be associated with various mental health issues and may result in physical complications.
Body-focused repetitive behaviours are characterised by the compulsive urge to engage in actions that affect one's body, such as nail biting, hair pulling (trichotillomania), or skin picking (excoriation disorder). These behaviours can lead to visible physical damage and are often accompanied by psychological symptoms. In the case of onychophagia, individuals may experience distress, tension, or social embarrassment due to their nail-biting habit.
The exact causes of nail biting are not fully understood, but it is frequently associated with anxiety, stress, boredom, or a need for stimulation. It can also be a transferred habit from thumb or finger sucking. Additionally, there may be a genetic predisposition, as individuals with family members who are chronic nail biters are more likely to exhibit the behaviour themselves.
The classification of nail biting as a BFRB highlights its repetitive and compulsive nature. Individuals struggling with onychophagia may find it challenging to stop, even if they are aware of the negative consequences. This struggle is not due to a lack of willpower but rather the addictive nature of the behaviour, which provides immediate satisfaction or relief. As a result, breaking the habit often requires a combination of strategies and professional assistance.
Effective treatments for onychophagia aim to address both the physical and psychological aspects of the behaviour. Cognitive-behavioural therapy (CBT) is considered the gold standard, helping individuals identify unhelpful behaviour patterns and replace them with healthier alternatives. Identifying triggers is a critical aspect of treatment, as it enables individuals to develop strategies to manage their urges effectively. For example, keeping nails trimmed or using bitter-tasting nail polishes can reduce the temptation to bite. Additionally, addressing any underlying mental health issues is essential for long-lasting behaviour change.
