Regardless of their form or function, snakes regularly replace their teeth to ensure they are always prepared to capture prey. In the case of snakes with long fangs, the fangs will fold back into the mouth to prevent self-biting. When a snake loses or breaks a fang, it will grow a new one.

Snake species with fangs shed their fangs approximately every six to eight weeks, and new fangs will replace the old ones. This constant renewal ensures that the snake has fresh and sharp fangs for biting and injecting venom into its prey.
