What is a Food Bolus? A food bolus is a small, round mass of food that is formed in the mouth during the early phase of digestion. A food bolus is formed when a piece of food is chewed, lubricated with saliva, mixed with enzymes and formed into a soft, lubricated and cohesive mass. The bolus is held in the mouth, or oral cavity, until the process of swallowing begins.
This is called the period of mixed dentition, because for much of the time, children will have both primary and permanent teeth. Teeth form under the gum before they erupt (emerge through the gum). The crown, or visible part of the tooth, forms before the roots do. Before the roots form, the developing tooth is called a tooth bud.. Eventually, the 20 primary teeth are replaced by 32 permanent teeth.
