Shark Teeth Identification
Unlike adult humans, sharks are constantly growing new teeth to replace those they lose. You may find some of these shed teeth on the beach or for sale in souvenir shops. To determine what shark the tooth is from, use the guide below and consider the shape, serrations, length of the blade and length of the root.

Triangular Teeth
-
If the blade is shaped like an isosceles triangle---like the side of a pyramid---and serrated like a steak knife on the two sides, and the blade is longer than the width of the root, you've got a tooth from a Great White shark.
Knife Blade
-
If the tooth is long and slender, and reminds you of a knife blade, and has two tiny but sharp spikes near the base of the main blade, you have a Sand Tiger tooth.
-
No Serrations
-
If the tooth isn't serrated, and the blade is shorter than the root is wide, you have a tooth from a Lemon shark.
Two-Part Tooth
-
If the blade of the tooth seems to consist of two differently shaped parts--the front a serrated, backward-pointing blade, and the rear curved with deep serrations--you're looking at a tooth from a Tiger shark.
Bent Triangle
-
If the tooth is triangular but one side seems slightly bent, the root and blade are about the same length and the blade is serrated, you probably have a Bull shark tooth.
