How Many Teeth Does a Shark Have?
The number of teeth a shark has is different for each species, but some can have more than 35,000 teeth in their lifetime. Unlike humans, who have a limited number of teeth, sharks have a continuous tooth replacement system. Some sharks have several rows of teeth, but they mostly use the front two rows. As teeth are lost or worn down, new teeth from the rows behind move forward to take their place. This process is ongoing, ensuring that sharks remain effective hunters throughout their lives.
