Final answer:
The number of point angles or cusps varies by type of tooth; incisors have none, canines have one, premolars have two, and molars have several.
Step-by-step explanation:
Every tooth has a specific number of point angles, also referred to as cusps, depending on its type.
Incisors have a sharp edge for biting with no distinct cusps, canines have one cusp for tearing food, premolars typically have two cusps for crushing food, and molars have multiple cusps for grinding food.
For example, incisors and canines have a single point at their tips, each premolar has two points, and the number of points can vary per type of molar but is generally more than two.
