The Science Behind Nail Biting
Nail biting is considered a body-focused repetitive behavior (BFRB), a type of repetitive self-grooming habit that can sometimes cause unintended harm. The habit is a behavior which usually starts at an early age and lasts even up to adulthood, with possible causes including frustation, excessive concentration, stress, and anxiety. A review on onychophagia notes that the temporary sense of relief of relaxation from biting may reinforce the behavior, making it more automatic over time.
Since nail biting repeatedly brings the fingers and nails into contact with the mouth, its effects can extend beyond the habit itself. But does this repetitive action have any influence on the color of your teeth too?
Can Nail Biting Cause Tooth Discoloration?
Even though there is no connection between nail biting and tooth stains, nail biting may still affect your smile's appearance. The Centers for Disease Control and Prevention notes that bacteria and germs can collect under your fingernails. So, when you bit your nails, you may also be bringing some of those microorganisms into your mouth.
In fact, a 2007 study published in Oral Microbiology and Immunology found Enterobacteriaceae in the saliva of 76% of nail-biter, compared with 26.5% of peopler who didn't bite their nails. This does not imply that nail-biting is responsible for causing tooth discoloration. However, it implies that the behavior increases exposure to bacteria. Research has also found that some bacteria associated with dental plaque
Plaque is a biofilm that normally forms in the mouth because of bacteria. When plaque remains uncleared, it forms deposits on the teeth. Some of the chromogenic bacteria present in the dental plaque cause production of pigment that contributes to tooth discoloration.
Aside from its potential connection to plaque and tooth discoloration, nail biting may also have other effects on your oral health. Find out more in our guide: Can Nail Biting Damage Your Teeth? Effects, Risks & Prevention Tips
How to Keep Nail Biting From Affecting Your Smile
Even if nail-biting and tooth staining are separate problems, they both can have an impact on your smile. Here are a few easy methods for dealing with both issues.
Address Your Nail-Biting Habit
You can find several ways to control nail biting ranging from something you can do on your own to what a professional will help you with.
-
Know your triggers. Figure out when you tend to bite your nails, such as when you're stressed, bored, or concentrating.
-
Make your hands busy. Whenever an urge arises, rub your fingertips, make a fist, or squeeze a small object instead.
-
Make it less rewarding. Maintain well-manicured nails or try applying nail polish that is bitter tasting so as to stop yourself from engaging in the behavior.
-
Consider professional support. If nail biting feels difficult to control or causes injury, a mental health professional can help you explore behavioral approaches.
Maintain a Clean and Bright Smile
Besides helping you stop nail biting, the following simple actions will help maintain a white smile:
-
Keep up with good oral hygiene. Brushing should be done twice daily, while interdental cleaning should be done on a daily basis and you must have dental cleanings regularly.
-
Reduce staining substances. Coffee, tea, red wine, and other dark-colored foods and drinks can leave surface stains on your teeth. When you can, rinse your mouth with water afterward.
-
Go easy on acidic foods and drinks. The consumption of food and drink which are acidic could cause harm to your enamel, causing the tooth to become discolored.
-
Avoid smoking or vaping. These will make your teeth become stained and discoolored.
- Consider whitening your teeth. In case of surface stains, teeth whitening might prove effective. At-home teeth whitening kits can be a convenient option when used as directed.
