Nail biters are also more prone to develop colds and flu. After all, your hands are teeming with bacteria, especially beneath the nails. If your fingers are always in your mouth, the bacteria they touch land there too.
Researchers found that kids who nibbled their nails were less likely to get allergies and had stronger immune systems overall. Nail biting allowed bacteria and pollen trapped under the kids' fingernails to get into their mouths, boosting their immunity.
Constantly bringing your nails into your mouth can bring E. coli, salmonella and the germs that cause the common cold as well as a plethora of others that may cause you to get sick. “Pathogens which transfer from your nails to the mouth during nail biting can lead to illness,” says Dr. Condello.
Increases Risk of Other Infections
Although this isn't directly an oral health concern, when you bite your nails, you bring germs into your mouth. This increases your risk of getting a cold, the flu, or another infection.
The Diagnostic and Statistical Manual of Mental Disorders, Fifth Edition, categorizes chronic nail biting as other specified obsessive-compulsive disorder (OCD), classified in the same group as compulsive lip biting, nose picking, and hair pulling (American Psychiatric Association, 2013).
Additionally, if you swallow the nails, they can do damage to the epithelial lining of your esophagus and stomach. They will not digest, so if they're sharp, they will make their way through your entire body potentially scratching up your digestive tract.
Nail biting was also more common in patients with TS with ADHD than in those without (75.0% vs 47.6%; p<0.001), but the starting age was significantly later in those with concomitant ADHD than without (5.3 vs 3.8 years; p<0.001).
Every time you bite your nails, you are probably ingesting most of those germs, which can cause throat and gum infections and more.
Onychophagia, or onychophagy, is considered a pathological oral habit and grooming disorder characterized by chronic, seemingly uncontrollable nail-biting that is destructive to fingernails and the surrounding tissue.
Nail biting explained
Anxiety: Nail biting can be a sign of anxiety or stress. The repetitive behavior seems to help some people cope with challenging emotions. Boredom: Behaviors such as nail biting and hair twirling are more common when you're bored, hungry, or need to keep your hands busy.
While common nail-biting is a socially recognized “nervous habit”, compulsive nail-biting can be injurious and interfere with everyday functioning. While these BFRBs may look similar to behaviors one might see with Tourette's, they are not tic behaviors.
Self-stimulatory behavior, often called “stimming,” is when a child or adult repeats specific movements or sounds as a way to self-soothe or remain engaged in a situation, often referred to as “fidget to focus.” Many people assume that only individuals with autism engage in self-stimulatory behaviors.
Some of the reasons children bite their nails includes stress or anxiety, they are bored, they've seen other children do it and copy their behaviors, or their nails are not kept trimmed and they do it as a form of self-trimming. Most children that bite their nails have no problems.
It can increase your risk of infection around the nail, especially if you bite at your cuticle or the soft tissue around it. It can harm your teeth. It can spread germs on your hands and fingers to your mouth, increasing your risk of getting sick.
Needles, pins, keys, nails and bones are among the most commonly ingested foreign bodies. Severe complications are uncommon, but if present they can put patients' lives at risk. Although extremely rare, the ingested foreign body may end lodging in the appendix, posing a challenge for the clinical team.
A: Doctors classify chronic nail biting as a type of obsessive-compulsive disorder since the person has difficulty stopping. People often want to stop and make multiple attempts to quit without success. People with onychophagia cannot stop the behavior on their own, so it's not effective to tell a loved one to stop.
While most people assume nail biting has to do with nerves or anxiety, one study is linking this bad habit to a surprising personality trait. According to a study published in the March 2015 issue of Journal of Behavior Therapy and Experimental Psychiatry, nail biters are more likely to be perfectionists.
Several studies indicate that there is a genetic component to nail biting (also known as onychophagia). One study has shown that 36.8% of nail biters had at least one family member with this habit. Studies of twins have shown that identical twins are more likely to both be nail-biters than non-identical twins.
When it comes to tics and autism, yes tics are common in people with autism spectrum disorder (ASD). Tics affect approximately 1 percent of the population, Tourette syndrome causes both verbal and motor tics.
Tics are brief, unwanted repetitive movements.
Common tics include: blinking, wrinkling the nose, eye rolling or grimacing. jerking, tossing, or banging the head. cracking the finger joints.
But they do know that it's a habit for a lot of us: about 20 to 30 percent of the population are nail biters, including up to 45 percent of teenagers.
