tooth. 1. (in most vertebrates) one of the hard bodies or processes usu. attached in a row to each jaw, serving for the prehension and mastication of food, as weapons of attack or defense, etc., and in mammals typically composed chiefly of dentin surrounding a sensitive pulp and covered on the crown with enamel.
A tooth (plural teeth) is a small, calcified, whitish structure found in the jaws (or mouths) of many vertebrates and used to break down food.ndeed, teeth appear to have first evolved in sharks, and are not found in the more primitive jawless fish-while lampreys do have tooth-like structures on the tongue, these are in fact, composed of keratin, not of dentine or enamel, and bear no relationship to true teeth.
