Sounds like a shark.
Sharks actually don't normally have any really hard bones in their body at all - the closest they have is cartilage, which has the benefit of being light and flexible. Their teeth are no exception. From an evolutionary standpoint, they seem actually to be adapted scales, and very much like finger nails (and other scales) they are constantly growing.
This is a good thing for sharks because not being very hard or well-anchored, they are constantly being broken and lost. A look into a shark's maw (hopefully from the safe side of a set of bars, at least) will reveal rows and rows of teeth. New ones are constantly being formed on the inside of the mouth and maturing ones are pushed forward. Some sharks grow a new row of teeth every 8-10 days! Which means they're losing them just as fast!
While rodents do have SOME teeth that are continually growing throughout their lives, not ALL their teeth do - just their incisors. Rat molars develop and then stop growing, just like ours do.

You often hear the phrase "a bit long in the tooth" meaning "old." I have always been told this phrase refers to horses, whose teeth continue to grow throughout their lives. However, horses are by no means the only animals whose teeth do this ... beavers, for example, have fast-growing teeth that are kept under control by constant gnawing!

Rodents and rabbits have to grind down their incisor teeth on a regular basis. Boars and elephants tusks continue to grow throughout their lives. I believe hippopatumus teeth grown continually also.

a whale's teeth is the same material of our finger nails so I'm guessing that is it. i probably have it wrong.

Rodents.( unless they gnaw on something, their teeth will puncture their mouths eventually.)
