Why Shark Teeth Are So Sharp

  • Serrated edges – Act like mini knives to slice cleanly through flesh, bone, and tendons.
  • Hard enamel coating – Up to 5x harder than human tooth enamel. Resists abrasion from bites.
  • Constant replacement – New teeth grow in rows behind old teeth. Ensures fresh, sharp teeth.
  • No tooth decay – Sharks have high fluoride levels which prevent cavities.

Key Facts About Shark Teeth

  • Sharks can have up to 15 rows of teeth at one time
  • They lose teeth regularly but replace them quickly
  • Shark teeth are made of dentin covered in hard enamel
  • The shape and size of teeth depends on diet and prey
  • Sharks produce 20,000-30,000 teeth over a lifetime
Why Shark Teeth Are So Sharp

The Anatomy of Shark Teeth

Shark teeth consist of:

  • Dentin – Dense mineralized tissue that forms the core of the tooth. It is harder than human bone.
  • Enamel – The outer coating made of fluoride compounds. Enamel is the hardest substance in the shark’s body.
  • Serrations – Jagged edges along the tooth shape. They act like small blades to slice through prey.
  • Roots – Shark teeth are not rooted like human teeth. They anchor into soft gum tissue.

Tooth Shape and Function

TriangularWide base with pointed tipTaking large bites out of big prey
SerratedBlade-like with jagged edgesSlicing through tough hides and bone
Molar-likeFlat and wideCrushing hard-shelled prey like clams and crustaceans


  • Shark teeth are optimized by evolution for hunting and feeding efficiency. Their shape, hardness, and serrated edges allow them to tear through prey with ease.
  • Tooth replacement and lack of decay means sharks always have a fresh set of razors ready to go.
  • The great white shark possesses the perfect tooth structure to inflict devastating wounds. Their teeth can rival steel knives in sharpness!
