In taxonomy, shark teeth are counted as follows: rows of teeth are counted along the line of the jaw, while series of teeth are counted from the front of the jaw inward. [19] A single tooth row includes one or more functional teeth at the front of the jaw, and multiple replacement teeth behind this. [ 20 ]
The mineral distribution in rodent enamel is different from that of monkeys, dogs, pigs, and humans. [12] In horse teeth, enamel and dentin layers are intertwined, which increases the strength and decreases the wear rate of the teeth. [13] [14] Contrary to popular belief, horse teeth do not "grow" indefinitely. Rather, existing tooth erupts ...
It has been estimated that the average shark loses about 30,000 to 40,000 teeth in a lifetime. Leopard sharks routinely replace their teeth every 9–12 days and this is an example of physiological regeneration. This can occur because shark teeth are not attached to a bone, but instead are developed within a bony cavity. [74]

Shark teeth are strong and made of enamel. Many sharks have 3 rows of teeth. These teeth are embedded in the gums, not the jaw. [10] Sharks are born with teeth that are constantly being replaced. Teeth are replaced every two weeks, approximately. [10] The shape of the teeth determine the diet of the shark.
The teeth of Strigilodus tollesonae were “spoon-like,” which is considered ideal for crushing, McClatchy News reported. Teeth embedded in cave walls reveal new species of ancient sea creature ...
