# Teeth with longest roots in human dentition are:
A. Incisors
B. Canines
C. Premolars
D. Molars
The correct answer is B. Canines.
Canines possess the longest roots of all teeth and are located at the corners of the dental arch. They function in the seizing, piercing, tearing and cutting of food. From a proximal view, the crown also has a triangular shape, with a thick incisal ridge. The anatomic form of the crown and the length of the root make these teeth strong, stable abutment teeth for a fixed or removable prosthesis.
