Nail biting, or onychophagia, is a common habit that often begins in childhood or adolescence. While it may provide temporary stress relief, nail biting can lead to several issues, including sore and infected fingers. This is because nail biting can cause minor injuries to the nail bed and cuticle, allowing bacteria and fungi to enter and cause infections such as paronychia, which can result in throbbing pain, swelling, and redness around the nail. Additionally, aggressive nail biting can lead to skin damage, creating an easy entry point for germs and increasing the risk of illness. To alleviate pain and prevent infection, it is recommended to soak the affected finger in warm water and apply moisturising cream.

Nail biting can cause paronychia, a bacterial infection with symptoms like throbbing pain, swelling and redness
Biting your nails can cause paronychia, a bacterial infection with symptoms like throbbing pain, swelling, and redness. Paronychia is a common nail infection that can cause throbbing pain, in addition to swelling and redness or discolouration of the finger, especially around the cuticle. It is usually caused by bacteria that invade the skin where it has been injured. In the context of nail-biting, this injury can be caused by biting the edges of the nails or the skin around them.
Paronychia can be acute or chronic. Acute paronychia appears as a sudden, very painful area of swelling, warmth, and redness around a fingernail or toenail, usually after an injury to the area. It is typically caused by an infection with bacteria that invade the skin where it was injured. Chronic paronychia, on the other hand, is caused by inflammation that usually develops slowly, causing gradual swelling, tenderness, and redness of the skin around the nails. It often affects several fingers on the same hand.
The treatment for paronychia depends on its severity and type. Acute paronychia can often be treated at home by soaking the affected finger or toe in warm water for at least 15 minutes, two to four times a day. If symptoms do not improve or if pus develops near the nail, it is recommended to consult a doctor. In moderate to severe cases, a doctor may treat acute paronychia with an oral or topical antibiotic. They may also drain any accumulated pus and remove a small part of the nail to ensure complete drainage. Chronic paronychia, meanwhile, may require several weeks of antifungal medication.
In addition to causing paronychia, nail-biting can introduce germs into the body, increasing the risk of illness. It can also cause skin damage, creating an easy entry point for bacteria and other pathogens. Furthermore, nail-biters may experience jaw problems and chipped, cracked, or broken teeth over time.

Biting your nails can chip, crack or break your teeth and may even cause jaw problems
Biting your nails can have several negative consequences for your health, including damage to your teeth and jaw. Nails are made of a hardened version of keratin, which is challenging for teeth to penetrate. As a result, biting your nails can chip, crack, or break your teeth. This can lead to significant amounts of pain and further dental issues.
Nail-biting can also cause your teeth to shift, weakening their roots and anchoring to your gums. This can create problems for orthodontic treatment. Additionally, nails often harbour bacteria and microorganisms, which can lead to a higher risk of oral infections and the spread of oral diseases when introduced to the mouth.
Fingernail biting is a common nervous habit, often serving as a coping mechanism for stress, boredom, loneliness, or anxiety. It is one of several body-focused repetitive behaviours, including hair plucking and skin-picking, and is related to obsessive-compulsive disorders. Chronic nail-biting can lead to the development of a teeth-grinding habit, which further increases the risk of jaw problems.
Stress-induced nail-biting can cause temporomandibular joint (TMJ) disorders, resulting in jaw pain, restricted jaw motion, jaw clicking or popping, and other symptoms. Stress can cause jaw muscles to tighten, reducing blood flow and oxygen delivery, leading to muscle soreness, spasms, pain, and fatigue. This can progress to reduced jaw motion and changed bite, potentially causing jaw joint instability.
To prevent these issues, it is essential to break the nail-biting habit. This can be achieved by identifying triggers, finding alternative stress-coping mechanisms, and seeking professional help through cognitive-behavioural therapy (CBT) or acceptance and commitment therapy (ACT) if needed.

Hands are a hotbed for germs, so nail biting increases your chances of getting sick
Biting your nails can lead to several issues, including pain and infection. Hands are a hotbed for germs, and nail biting increases your chances of getting sick. Our hands come into contact with countless surfaces throughout the day, many of which are teeming with bacteria and viruses. When you bite your nails, you're essentially inviting those germs into your mouth, where they can cause various illnesses.
The nails themselves can also be a breeding ground for bacteria and fungi, which can lead to nail infections. These infections can be quite serious and may require medical attention. When you bite your nails, you create tiny tears and cracks in the nail plate, providing an easy entry point for these pathogens. This can result in conditions such as paronychia, an infection that causes pain, swelling, and redness around the nail. In some cases, it may even lead to a bone infection in the finger or toe.
Additionally, biting your nails can cause skin damage, creating another entryway for germs to enter your body. This damage can also increase the risk of fungal infections, such as athlete's foot, which can spread to other nails and the skin. These infections can be challenging to treat and may require prescription medication or even surgery in severe cases.
The act of nail biting can also introduce germs directly into the body through the mouth. This can lead to gastrointestinal issues and other illnesses. Furthermore, the constant moisture and warmth created by the mouth provide an ideal environment for bacterial growth, further increasing the risk of infection.
To reduce the risk of infection and illness, it is essential to break the nail-biting habit. This can be challenging, as nail biting often stems from emotional or psychological triggers. However, with persistence and the right plan, it is possible to stop biting your nails. Identifying triggers and finding replacement behaviors, such as squeezing a stress ball or chewing gum, can be effective strategies. In more severe cases, cognitive-behavioral therapy (CBT) and acceptance and commitment therapy (ACT) can help address the underlying psychological causes.

Skin damage from nail biting can cause infections and lead to pain
Biting your nails can cause skin damage, which can lead to infections and pain. Nails and the skin around them are a hotbed for germs, and biting your nails can create an easy way for these germs to enter your body. In addition, biting your nails can cause injuries to the nail bed and cuticles, which can become infected. This is known as paronychia, which can cause throbbing pain, swelling, and redness in the affected area.
Paronychia can be acute or chronic. Acute paronychia usually appears as a sudden, very painful area of swelling, warmth, and redness around a fingernail or toenail, typically after an injury. It is caused by an infection with bacteria that invade the skin where it has been injured. Biting the edges of the nails or the skin around them can cause this type of injury. Treatment for acute paronychia involves soaking the affected finger or toe in warm water for at least 15 minutes, two to four times a day. In more severe cases, a doctor may prescribe an oral or topical antibiotic, and in some instances, part of the nail may need to be removed to allow the area to drain completely.
Chronic paronychia is caused by inflammation that develops slowly, causing gradual swelling, tenderness, and redness of the skin around the nails. It often affects several fingers on the same hand and is more likely to occur in people with diabetes or those who are constantly exposed to water, chemicals, or other substances through their work. Treatment for chronic paronychia may require several weeks of antifungal medication.
In addition to paronychia, biting your nails can also increase the risk of fungal nail infections. These infections can cause pain, as well as discolouration of the nails, making them turn yellow or white. Without treatment, fungal nail infections can spread to other nails and, in rare cases, cause permanent damage to the nail bed.
To prevent skin damage and infections from nail-biting, it is important to break the habit. This can be challenging, but there are several strategies that can help. One approach is to identify the triggers for nail-biting and find replacement behaviours, such as squeezing a stress ball or chewing gum. Keeping nails trimmed and using bitter-tasting nail polish can also help deter nail-biting. In more persistent cases, cognitive-behavioural therapy (CBT) and acceptance and commitment therapy (ACT) can be effective in addressing the underlying psychological causes of the behaviour.

Biting your nails can be a sign of emotional or mental stress
Biting your nails can cause your fingers to hurt due to several reasons. Firstly, nail biting can cause or exacerbate nail infections, also known as paronychia. This condition typically causes throbbing pain, swelling, and redness around the nail, and it can be caused or worsened by biting the nails or the skin around them. In more severe cases, paronychia may lead to an accumulation of pus, requiring medical attention.
Additionally, nail biting can create small injuries or irritations around the nails and cuticles, which can be painful and increase the risk of infection. This is because the hands and nails are a common hiding place for germs, and putting your fingers in your mouth multiple times a day increases the likelihood of getting sick. Moreover, the skin damage caused by nail biting provides an easy entryway for bacteria and fungi to enter the body.
Nail biting is often a coping mechanism or a habit that develops in response to emotional or mental stress. It is commonly associated with feelings of nervousness, anxiety, boredom, loneliness, or hunger. For some, it may be a way to cope with these emotions. In fact, pathological or severe nail biting is classified as a body-focused repetitive behavior (BFRB) and is related to obsessive-compulsive disorders.
If you are experiencing finger pain due to nail biting, there are several ways to address the issue. Firstly, it is important to try to break the nail-biting habit. This can be challenging, but setting small goals, such as choosing one nail not to bite, can help. Finding replacement behaviors, such as squeezing a stress ball or chewing gum, can also be effective. Trimming your nails short and coating them with a bitter-tasting nail polish may also deter you from biting them. If you are unable to break the habit on your own, cognitive behavioral therapy (CBT) and acceptance and commitment therapy (ACT) can help address the underlying psychological causes.
