Nail biting, medically
referred to as Onychophagia, is a relatively common oral-compulsive habit that
affects people of all ages. There are many reasons why people bite their nails,
like in times of stress, frustration, or excitement, or in times of inactivity
or boredom during childhood.
Nail biting is
arguably the most common of the typical “nervous habits” including
nose-picking, thumb-sucking, and hair twisting. The habit usually begins in
childhood. Studies suggest that an estimated 60 percent of children and 45
percent of teenagers bite their nails, and drop the habit as they get into
adulthood. However, about 25 percent of young adults and 5 percent of older
adults continue to bite their fingernails.
Conscious or not, the
habit can cause major damage to your teeth, because you’re biting on something
hard. Here are some other consequences of biting your teeth:
1. Chipped
teeth
This is arguably the
biggest reason why you should stop biting your nails. Consistently chewing on
your hard fingernails can flex your teeth’s enamel, causing it to chip or
fracture. Additionally, when you bite through a fingernail, the teeth hit
together quite hard, which could also chip the tooth. Besides enamel wear, nail
biting can also lead to uneven biting surfaces.
2. Misaligned teeth
Biting your
fingernails usually exerts a lot of pressure on the front teeth, which they are
not designed to withstand. Although teeth are naturally hard and durable, the
shearing stress created by nail biting can cause the incisors to become
misaligned or cause a diastema – gap between the teeth - damaging the most
important part of your smile. This will cost you a lot in future to fix your
smile.
3. Increased risk for Temporomandibular ™ disorder
Nail biting can
contribute to TMJ, which results in headaches, jaw pain, and locking and
popping of the jaw. Other studies also claim that biting fingernails puts you
at greater risk for bruxism – unconscious grinding and clenching of teeth –
which is associated with a bunch of negative effects.
4. Damage to dental appliances
Appliances like braces
exert a lot of pressure on teeth, and adding to this pressure by biting your
fingernails can stress your teeth out, weaken them, and damage your orthodontic
treatment and overall bite.
5. Sanitary concerns
Hands are one of the
most germ-laden areas of the human body, even for compulsive hand washers, and
nails are doubly so. Biting your fingernails creates an avenue for you to
transfer disease causing germs, including the potentially pathogenic Salmonella
and E. coli bacteria, from your hands into your mouth, leading to infections.
Final note
Damage can also occur
to your fingers in the form of a skin infection, like paronychia, whereby
bacteria and other microorganisms penetrate the skin through tiny tears around
your nails, leading to redness, swelling, and pus around the nails, which can
lead to social stigma.
Fortunately, nail
biting can be fixed through a number of expert approved strategies, like
keeping your nails short, coating your nails with a sour-tasting polish, and
picking up stress management habits like meditation, exercise, and yoga to calm
you instead of biting your nails.
