I'm not for sure what you mean but if a shark loses a tooth it takes 24 hours to grow back.

That would depend on if your a child or not. you have two sets of teeth in your life time, when you are a child and lose a tooth an adult tooth takes its place, if your an adult and lose a tooth it does not grow back.

New teeth grow to replace those the shark has lost, Because it has back up rows of teeth behind those that it loses. Sometimes they can have up to 5 rows of teeth at one time!From what i understand about sharks is that they (unlike humans) continue to make teeth throughout their lifetime. Tiger sharks included.
