Nail biting can cause hangnails, which are open sores that can become infected
Hangnails are a common side effect of nail biting. They are small, torn pieces of skin that appear at the root of the nail. These open sores can easily become infected, as they provide a direct route for bacteria and viruses to enter the body. This is especially true if you swallow your bitten nails, as this can lead to stomach or intestinal infections.
The skin around your nails can also become sore and damaged from repeated nail biting. This can affect the tissue that makes nails grow, resulting in abnormal-looking nails. Chronic nail biting can leave you vulnerable to infection, as you are passing harmful bacteria and viruses from your mouth to your fingers and from your nails back to your face and mouth.
In addition to the risk of infection, nail biting can also cause other issues. For example, if you have warts on your nails, biting them can cause the warts to spread to other areas. Nail biting can also lead to dental problems, such as shifting teeth, broken teeth, or damaged tooth enamel. The bacteria on your fingers and nails can also cause bad breath.
To reduce the risk of hangnails and infection, it is important to break the habit of nail biting. Dermatologists recommend keeping your nails trimmed short, as this provides less nail to bite and can make the habit less tempting.
