Have you ever wondered why we need our teeth to chew our food?



The dictionary defines tooth as:

1. one of the hard bony growths that are borne on the jaws of other bones in the walls of the mouth or pharynx and are necessary for the grasping and grinding of food or as weapons of offense and defense.


Human teeth are very necessary for chewing. The teeth are also involved in the process of speech and they also give the face its appearance.


The teeth are of three general types: incisors, the cuspids, and the molars.
