Incisor Teeth Anatomy and Function
The incisors are located at the anterior (or front) portion of the mouth. Each dental arch has two central incisors, which are separated by the mouth’s midline, and two lateral incisors that sit alongside the two central incisors distally.
Canine (Cuspid) Teeth
Next you have the canine teeth, which are also called cuspids or “ eyeteeth .” If you consider the name of these teeth then you’ll always remember them because “cuspid” means “point”, and canine refers to dogs, which have those sharp, pointy teeth.
Premolar (Bicuspid) Teeth
Distal to the canine/cuspid teeth are the bicuspid teeth, which are also called premolars. In each quadrant, you have a first premolar, which is distal to the canine, and a second premolar, which is distal to the first premolar.
