1. Incisors: The upper and lower jaws include a total of eight front teeth. These are called incisors. The pair of teeth which makes up the middle portion of your mouth, both top and bottom, is called central incisors. Lateral incisors are the teeth that are located on each side of the central incisors. The main characteristics of all incisors are that they are broad and have a narrow sharp edge with which they can cut or snip off food. They possess a single root.
2. Canines: There are a total of four teeth on both sides of the upper and lower incisors. They are called canines, cuspids or eyeteeth. They are the most stable and longest teeth. They are good for tearing and ripping off food that is tough, for instance meat. They have a single sharp point and they are thick. They possess a long single root.
3. Premolars: There are two premolars next to each of the canines. There are a total of eight canines. Premolars are also known as bicuspids. These teeth are considered as a cross between molars and canines. They come with sharp points. They are ideal for ripping and tearing and also for grinding and chewing due to their broad surfaces. The first premolars on each side of the canines in the upper jaw have two roots. The second premolars possess one root. The premolars in the lower jaw possess one root.
4. Molars: The last three teeth on each side of the mouth on the upper and lower jaw are called the Molars. There are a total of 12 molars. The first molars are located just next to the second premolars. These are also known as the 6-year molars. The third and last molars are also known as the wisdom teeth. The second molars are also known as the 12-year molars. Molars are ideal for chewing, grinding and crushing food.
