Ingrown toenail can be prevented by cutting the nail straight across

Onychocryptosis literally means hidden nail; the common name is ingrown nail.

To properly remove an ingrown fingernail or toenail, you should soak it in warm water for at least 15 minutes, then you should gently pull back on the skin going around the area the ingrown nail is in and put a small piece of cotton underneath the nail to keep the skin from growing over the nail even more. You should also be sure to cut the nail properly and clean it reguarly.
