Which type of teeth are described as single rooted and located at the front of the mouth?

Molars
Incisors
Canines
Premolars

The correct answer is: Incisors

Incisors are categorized as single-rooted teeth that are situated at the front of the mouth. Their primary function is to cut and shear food, which aligns with their sharp, thin shapes. They typically have a flat edge that aids in biting into food, making them essential for the initial phase of mastication. In contrast, molars, located at the back of the mouth, usually possess multiple roots and are designed for grinding food, featuring a broader surface area. Canines, while they do have a single root like incisors, are positioned next to them and serve a different role—primarily tearing food due to their pointed shapes. Premolars, situated between canines and molars, usually have two or more roots and are larger than incisors, functioning mainly to crush and grind food. Hence, incisors are distinct for their front positioning and singular root structure.
