How Nail Biting Affects Your Teeth
It seems harmless, but nail biting is tough on teeth and jaws. Here is what it does and how to break the habit.
Nail biting is one of the most common nervous habits, and it often starts in childhood. Most people think of it as a cosmetic issue for their hands, but it can take a real toll on teeth, gums, and jaws.
How It Affects Your Mouth
- Chipped and worn teeth. Repeatedly biting down on hard nails can chip enamel and wear the edges of front teeth.
- Jaw strain. Holding the jaw forward to bite puts extra stress on the jaw joint and can contribute to TMJ discomfort.
- Gum irritation. Sharp nail edges can injure gum tissue.
- Bacteria. Hands and nails carry germs straight into the mouth.
- Orthodontic setbacks. For people in braces or aligners, the extra pressure can slow progress or damage appliances.
Tips to Break the Habit
- Keep nails trimmed short so there is less to bite
- Try a bitter-tasting nail polish made for this purpose
- Notice your triggers, such as boredom or stress, and plan a replacement
- Keep your hands busy with a stress ball or fidget item
- Get regular manicures; many people are less likely to bite nails that look nice
Repairing the Damage
If biting has already chipped or worn your teeth, dental bonding is often a quick way to restore their shape. If you also clench or grind, a night guard can help. Schedule a visit and we will take a look.
