The human teeth dental chart illustrates the location and roles each tooth plays in performing their jobs of cutting, grinding and crushing food. Teeth differ in size, shape and their placement in the jaws. These variations allow teeth to work together to help you chew, talk and smile as well as to help shape your face, giving it its form.
Primary Human Teeth Dental Chart (Baby teeth)
At the time of birth, tooth buds are already in place. Babies typically have 20 primary (baby) teeth, which usually begin to erupt typically around 6 months of age but can be anywhere between approximately 3 months of age until 12 months to begin the accommodation of solid foods and the change in baby’s diet. The above human teeth dental chart are of children’s 20 primary teeth.
Cutting teeth takes time and can be painful for babies, which is usually completed by the age of 3. Teeth start to fall out at various times throughout childhood and by the age of 21; all 32 of the permanent teeth have usually erupted.
Eruption of Primary Teeth Dental Chart
Usually, humans get two sets of teeth during a lifetime. The first, primary or deciduous set is comprised of the 20 “baby” teeth. The second permanent set usually consists of 32 teeth. In each quadrant, there are eight permanent teeth including two incisors, one cuspid, two bicuspids, and three molars.
Eruption of Permanent Teeth Dental Chart
The pictorial below of permanent human teeth can help you to understand the positioning of each of your 32 permanent teeth in an adult mouth. The last teeth to arrive are the three molars. The third molars are more commonly referred to as the “wisdom tooth.”
Tooth Chart Positioning
The upper teeth of arch on the human teeth dental chart are called maxillary teeth because their roots are placed within the upper jawbone of the maxilla. Those of the lower arch are called mandibular teeth because their roots are embedded within the lower jawbone of the mandible. Each arch contains 16 teeth, composed of 6 anterior, and 10 posterior and in a quadrant, there are 3 anterior and 5 posterior teeth.
On this human teeth diagram, there are four classes of teeth, incisors, cuspid, bicuspid and molars, based on appearance, position and complementary functions.
A tooth is a hard, bony appendage that develops on the jaw to pulverize food. In man, the design of the teeth is a reflection of eating habits, as humans tend to be meat eaters so teeth are formed for cutting, tearing, and grinding food.
The human teeth dental chart illustrates the types and working surfaces of the four classes of teeth.
|On the dental chart, incisors are located in the front of the mouth and have sharp, thin edges for cutting. Their use is to incise or cut food and the appearance tends to have a shovel-shaped appearance.|
|Cuspids, also referred to as canines, are at the angles of the mouth on the tooth chart. Each has a single cusp and is designed for cutting and tearing.|
|Bicuspids, also referred to as premolars, are similar to the cuspids. They have two cusps used for cutting and tearing, and a wider surface to bite and crush food.|
|Molars are located in the back of the mouth. Their size gradually gets smaller from the first to third molar. Each molar has four or five cusps, is shorter and more rounded in shape than other teeth and has a broad surface for grinding and chewing solid food.|
When viewing the human teeth dental chart, it shows the typical human mouth. People are all different and do not always have every tooth come in or they may appear at different times. When extractions or exclusions occur, depending on the tooth, different methods can get chewing accomplished.
