What is the largest Dinosaur tooth ever found?

I am curious as to the size of the largest Dinosaur tooth that has been found,because of the recent find of a 10cm long tooth of an unidentified allosaur in Spain. Anyone?

Maybe the Megalodon shark, teeth found over 7 inches, over 18 cm.

hmmm every tooth ever? cause if so mybe mamoth or saber tooth?

The largest dinosaur tooth? It's not one of the sauropods. Reason: They may have been big, but they had extremely small skulls. I would say the biggest dinosaur tooth was probably the tooth of a Giganotosaurus or Carcharodontosaurus. Biggest in general would probably be Megalodon or Liopleurodon.

The largest teeth of a dinosaur? From what I've read, my best guess would be T-rex. An adult could have teeth up to 9 inches (23 cm.) long, and apparently one specimen (not sure which one) was found with teeth up to 13 inches (33 cm.) long.

...Although, I'm not entirely sure of this myself. I haven't ever really seen a dinosaur tooth especially closely, and those measurements were found on a website.

no t rex tooth 28 centimeters

yes your right a t rex tooth by far

gigantosaurus teeth are 15 centimeters

T.Rex has the largest tooth. I remember i had seen a picture of a t.rex Tooth placed inside a Glass case. It was 11 inches. And in some site i read about the 13 inches tooth of T.rex. I dont know in which site i read it. Anyway, in TV shows i had heard that Paleontologists mention that T.Rex has the Largest Tooth of any Dinosaur Known. So T.rex has a 1 feet tooth.

Yes, that's right. I read about it somewhere.
