Mastication means the process of chewing food. In the horse, food is grasped by the incisor teeth and moved back to the cheek teeth arcades by the combined action of the tongue and cheek muscles. The chewing motion of the mouth is controlled by several large muscles that act to slide the upper and lower cheek teeth against each other, breaking up the bolus of food before it can be swallowed.
The wear of the teeth in the grazing process can inform us of the horse's age thanks to the tooth morphology of this herbivore. The next sheets can help us to recognise the age of our horse.
