Molars are the grinding teeth found in the back of your mouth that work together with your incisors and canines. They are responsible for the efficient chewing of food. They are also known as grinding teeth, back teeth, or molar teeth. Depending on the type of molar, they can be characterized as premolars or wisdom teeth. Megalodonts, carnassial teeth, and cheek teeth are some synonyms for molars. Meaglodonts are the largest molar teeth found in prehistoric animals. Carnassial teeth are the sharp, blade-like molars used by carnivorous animals to cut and tear flesh. Cheek teeth are molars found at the back of the mouth that are used to grind and crush food.
