What are the basic forms of teeth?
In both dentitions there are three basic tooth forms: incisiform, caniniform, and molariform.
Incisiform teeth (incisors) are cutting teeth, with thin, blade-like crowns.
Caniniform teeth (canines) are piercing or tearing teeth, having a single, stout, pointed, cone-shaped crown.
Molariform teeth (molars and premolars) are grinding teeth possessing a number of cusps on an otherwise flattened biting surface.
Premolars are bicuspid teeth; they are peculiar to the permanent dentition and replace the deciduous molars.
