The term bicuspid tooth refers to a tooth that has two cusps or pointed edges. There are several different synonyms for this dental term, including premolar, bicuspids, and transitional teeth. Premolars are the teeth located between the canines and molars in the human mouth. They are called transitional teeth because they help transition food from the front teeth to the molars, which are better suited for chewing and grinding. Bicuspids or premolars are typically the first teeth to show signs of decay due to their location and shape, making regular dental checkups and cleanings essential for maintaining healthy teeth and gums.
