Explanation:
Incisors – The four front teeth in both the upper and lower jaws are called incisors. Their primary function is to cut food. The two incisors on either side of the midline are known as central incisors. The two adjacent teeth to the central incisors are known as the lateral incisors.
When you eat, canines help cut and tear food into bite-sized pieces, and when you speak, they work alongside the incisors to help form words. In addition, canine teeth function as guideposts to the rest of the teeth. They help maintain the position of the upper and lower teeth when the lower jaw moves side to side.
Just as their name indicates, premolars are located just before the molars in the human mouth. These teeth are also known as bicuspids. The premolars are considered transitional teeth, as they work to guide food from the cuspids near the front of the mouth back to the molars near the rear of the mouth for chewing.
Molars are rounded and used for grinding food into easily swallowed pieces. The smaller and sharper front teeth are used for biting and tearing food. Molars are designed to sustain great amounts of force from chewing, grinding, and clenching, and each molar is anchored to the jaw bone with two to four roots.
