How long are the longest animal's teeth?
A 4th grader, Mark Henry, has the record for the worlds largest tooth.An Ontario dentist had to pull the whopper of a chopper because it was interfering with the growth of Mark's other teeth. The Owen Sound Sun Times reports the monster tooth was nearly an inch long, so big the dentist calls it a horse tooth.You might think such an impressive incisor would be worth at least a couple of bucks from the tooth fairy. But alas, Mark lost his tooth when he took it to school to show his speech therapist.
