Could it harm your oral health?
Onychophagia is the habit of biting nails, often associated with factors such as anxiety, stress, or even a genetic predisposition. Although it may seem harmless, this behaviour can have negative consequences for oral health.


Consequences of nail biting:
Tooth wear – The pressure exerted while biting nails can wear down tooth enamel, making the teeth more fragile and prone to fractures.

Gum problems – Small nail fragments can cause injuries to the gums, leading to inflammation and increasing the risk of infections.

Tooth misalignment – Continuous nail-biting can affect the position of the teeth, causing bite issues and, in some cases, the need for orthodontic treatments.

Infections – Nails accumulate bacteria, viruses, and fungi, which, when transferred to the mouth, can cause infections in the oral cavity, and even in the gastrointestinal system.


How to stop biting your nails:
Take care of your nails regularly – Keeping nails clean and well-groomed can reduce the urge to bite them.

Apply bitter-tasting nail polish – There are specific products designed to discourage the habit.

Reduce stress – Relaxation techniques or regular physical exercise can help manage anxiety.

Stopping nail-biting is an important step towards improving oral health and preventing future problems. If this habit is affecting your well-being, consider seeking medical and dental advice.
