Types of Teeth and Their Functions: Incisors, Cuspids, Bicuspids, Molars | Teeth Anatomy

Learn different types of teeth and their functions with this teeth anatomy review. Humans have four main types of teeth: incisors, canines (cuspids), premolars (bicuspids), and molars.

These teeth form in the upper and lower jaws in the shape of an arch. You have an upper arch called the maxillary arch, and a lower arch called the mandibular arch.

The teeth can also be divided into four quadrants: Right maxillary (1), Left maxillary (2), left mandibular (3), and right mandibular (4).

Humans develop two sets of teeth throughout life, which are also called dentitions. The primary teeth erupt first, starting at around age 6 months. There are 20 of these teeth in total. The permanent teeth begin erupting around age six, and there are 32 of those teeth in a complete set.

Our teeth are very strong. And also good job, keep up the good work. Sometimes, our teeth don't get straightened or look like they've crossed.

What functions do I lose when I extract my premolars for braces? I’ve already done so, but am curious if I handicapped myself from properly performing certain tasks like speaking and chewing.
