Shark teeth have the same basic consistency as our teeth, but they don't sit in the mouth in the same way. Our teeth rest in sockets, and aren't replaced after childhood. Shark teeth are attached to the jaw by soft tissue, and they fall out all the time. In some sharks, such as the great white, these teeth are arranged in several rows.

Sharks have a very unique jaw structure, which makes their mouths especially effective weapons.
In most animals, the lower jaw moves freely but the upper jaw is firmly attached to the skull. In sharks, the upper jaw rests below the skull, but can be detached when the shark attacks its prey. This lets the shark thrust its entire mouth forward to grab onto its prey. Jaw mobility varies among different species, but all modern sharks have this ability to some degree. Inc.
