Then, we work our way back to the lower right quadrant, ending at Tooth #32. We continue counting our bottom teeth from Tooth #17 found in the lower left quadrant. Dentists and dental hygienists will count through to Tooth #16, located in the upper left quadrant. We start with Tooth #1, a molar on the back right side of our mouths known as the upper right quadrant. Our first 16 teeth are located at the top of the mouth. A healthy human mouth will have symmetrically arranged teeth so that teeth on opposing sides of the mouth will be of the same type. Now that we are familiar with the four types of teeth, we can easily pinpoint the location of each tooth in our mouths. Our canine teeth can have a more animalistic appearance, and some evolutionists believe humans developed canines to be able to consume meat. Canine teeth are distinctly sharper than our other teeth in order to effectively tear food into chewable chunks. Healthy mouths contain 4 canine teeth which flank our incisors (2 on the top and 2 on the bottom). Our incisors are designed for biting and gripping food for chewing. The center two incisors are known as “central”, while the two on either side are known as “lateral”. This tooth type is the first to emerge in infants as early as 6 months old. Our 8 frontmost teeth (4 on the top and 4 on the bottom) are referred to as incisors. Bicuspids usually have a flat surface to help tear food apart and assist the molars with food liquefaction. Each side of the mouth holds 4 premolars, or 8 premolars in total. Wisdom teeth are a type of molar which emerge at the very back of the gums in some dental patients.Īlso known as bicuspids, our premolars are slightly less strong than our molars. Molars are grown to be extremely strong to grind and crush textured foods for safe swallowing. A healthy set of teeth will have 12 molars arranged in the back of the mouth. Our molars are responsible for helping us thoroughly chew our food. Types of Human TeethĪdults have 32 teeth, which can be broken down into four categories: With this guide, you can feel more confident and prepared ahead of your next important dental procedure.
