State the function of the (a) incisor teeth (b) premolar teeth.
Answers
incisor teeth is the teeth which is used to bite the food and premolar teeth crushes the food in two small particles which helps our intestine to digest easily
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. Incisors have a single root and a sharp incisal edge.
Premolars – These teeth are located behind and adjacent to the canines and are designed to crush food. There are eight premolars in the oral cavity. There are two in each quadrant of the mouth. The one closest to the midline is the first premolar and the one farthest from the midline is the second premolar. These teeth can have 3-4 cusps. The maxillary first premolar has two roots, and the remaining premolars have a single root. There are no premolars in the primary dentition.
