Premolars, also known as bicuspids, are the teeth located between the canine and molar teeth in the dental arch. These teeth are used for crushing and grinding food during the process of mastication. Other synonyms for premolars include transitional teeth, first molars, and second molars, depending on their location in the dental arch and their stage of development. In some countries, premolars are also referred to as bicuspid teeth. These teeth play a crucial role in maintaining oral health and proper functioning of the digestive system. Therefore, it is essential to take good care of your premolars by practicing regular dental hygiene and visiting a dentist for check-ups.
