1. Damaging to Teeth
Teeth are susceptible to various injuries when you persist in the habit of nail-biting. Inadvertently, nail-biting leads to permanent damage to your teeth and even the gum line.
When constantly grinding teeth and nails, teeth can crack or chip. This may even result in misalignment, instability, or premature tooth loss.


2. May Result in Diarrhea
If you lack medical knowledge, you can still understand that nail-biting is not a healthy pastime. Bacteria residing in the mouth due to nail-biting habits can find their way into our intestines. These germs can cause infections in the stomach and intestines, leading to symptoms like abdominal pain and diarrhea. Prolonged conditions can significantly impact your health. When diarrhea causes dehydration, it results in fatigue.


3. Causes Bad Breath
Nail-biting is a habit prevalent not only in children but also in adults. This unsightly habit, often triggered by boredom or anxiety, not only affects teeth but is also a direct cause of bad breath.
Our nails harbor numerous bacteria, and even with regular handwashing, it's challenging to eliminate all germs and dirt beneath the nails. This means that bacteria will still be lurking under the nails, and when we bite them, these bacteria easily enter the mouth. These bacteria persist and thrive in the mouth, leading to gum diseases or even causing bad breath, making the breath unpleasant.


4. Causes Facial Acne
Nail-biting can also result in tiny cracks in the skin around the nails, allowing acne-causing bacteria to enter. Subsequently, bacteria can transfer from the fingers or nails to the face when touched or when biting nails.
This can lead to acne on the face, especially near the lips, as facial skin is very sensitive and prone to bacterial attacks. This can significantly impact both our health and aesthetics.


5. Prone to Cold or Flu
Aside from the mentioned illnesses, experts also warn about the possibility of contracting diseases stemming from the habit of nail-biting. Any activity involving touching the face increases the risk of disease transmission.
Nail-biting means making it easier for microorganisms to enter the body, including common cold-causing viruses.


6. Nail Deformities
From the uncontrollable habit of nail-biting, your nails can damage the underlying tissue and permanently deform.
At that point, they look rough, with extremely unsightly grooves. Along with that, the nails will not naturally grow long.


7. Linked to Chronic Headaches
According to a London-based scientist, biting nails can lead to teeth grinding during sleep, as nail-biting is a manifestation of stress and tension. This habit often accompanies other bad habits like teeth grinding.
This results in symptoms such as tense jaw muscles, jaw pain, facial pain, and chronic headaches. Some unnoticed nerve disorders in the nails pose a risk to our nervous system. Eliminate this bad habit to safeguard your mental and physical health.


8. Joint Inflammation
If external infections remain controllable, another consequence of habitual nail-biting is inflammation in hand joints.
This condition is commonly known as infectious arthritis, challenging to treat, and sometimes requires surgical intervention. Inflammatory arthritis in the hands can lead to permanent disability and, in severe cases, systemic infection.


9. Risk of Contracting Wart Virus
When the mouth comes into contact with the nails, it creates a favorable condition for bacteria on the hands to enter the body. HPV, a virus causing warts in humans, is particularly prevalent in individuals with a nail-biting habit.
If you bite your nails excessively, these wart particles may appear on your fingers, spreading to the mouth and lips, adversely affecting your health.


10. Serious Nail Infection Risk
Studies show that nails are, in fact, twice as dirty as fingers, harboring many hidden bacteria underneath. Even with regular handwashing, you can't fully clean the undersides and nail crevices. Prolonged nail-biting can lead to infections around the nails.
Frequent nail-biting increases the risk of paronychia (inflammation around the nails) causing infection in the surrounding skin. This infection results in swelling, redness, pus accumulation, and pain, requiring surgery and treatment with antibiotics or antifungal medications.
