How Nail Biting Affects Your Teeth and Gums: Risks You Should Know
Nail biting (onychophagia) is more than just a bad habit – it’s a serious threat to your oral health. At Emergency & Walk-In Dentist Cardiff, we regularly treat patients with dental damage caused by chronic nail biting. This guide reveals the hidden dangers to your teeth and gums, and when this habit requires emergency dental attention.
5 Ways Nail Biting Harms Your Oral Health
1. Tooth Fractures and Chips
Your nails are harder than you think:
- Repeated stress can cause small fractures in enamel
- May lead to complete tooth breaks requiring emergency dental repair
- Front teeth most vulnerable to chipping

2. Jaw Problems (TMJ Disorders)
The unnatural biting position:
- Overworks jaw muscles unevenly
- Can lead to chronic jaw pain and headaches
- May cause clicking/popping in jaw joint
Our dental treatments can help relieve TMJ symptoms
3. Gum Damage and Recession
Sharp nail edges can:
- Cut gum tissue, creating entry points for infection
- Cause gum recession exposing sensitive roots
- Lead to gum abscesses requiring urgent care
4. Bacterial Infections
Your nails harbor harmful bacteria:
- Transfer germs from nails to mouth
- Can cause tooth infections needing root canal treatment
- Increase risk of oral sores and ulcers
5. Orthodontic Damage
For those with braces:
- Can bend wires and loosen brackets
- Increases treatment time and costs
