The great white shark has approximately 50 full teeth in its jaw, according to the Fox Shark Research Foundation. It has from 24 to 26 teeth in the upper jaw and 22 to 24 in the lower jaw.
Great whites regenerate teeth constantly throughout their lives. Therefore, they actually have around 300 teeth that are fully developed or developing in their jaws at a given time. Developed teeth sit in rows of 5 to 7 teeth and perform the killing and chewing functions with prey. Developing teeth are not exposed. As front teeth wear and fall out, newly developed teeth slide forward.
