Shark teeth are not attached to flesh in the way that teeth in mammals are. Instead, they are embedded in the shark's gums and are held in place by a structure called the dental lamina. Sharks continuously shed and replace their teeth throughout their lives, with new teeth developing in rows behind the existing ones. This adaptation allows them to maintain a functional set of teeth for hunting and feeding.
