Molars are large, flat teeth located at the back of the mouth. They are designed for grinding and chewing food, making them essential for proper digestion. Adults typically have twelve molars, with three on each side of the upper and lower jaws. These teeth have a broad surface and multiple cusps, which help break down food into smaller pieces. Dental health is important for maintaining molars, as cavities and decay can lead to pain and tooth loss. Regular visits to a dentist can help ensure that molars and other teeth remain healthy.
