Molars are teeth that have three or four blunt cusps with which to crush and grind food. They are located at the back of the mouth (oral cavity).
Molar teeth generally have two roots or three roots, two in the case of the molars in the lower-jaw and three in the case of the molars of the upper-jaw.
The topics of digestion and teeth are included in some school e.g. GCSE and/or A-Level courses in subjects such as biology and human biology and in other courses that include human anatomy & physiology, diet, nutrition, and other health sciences.
