Types of teeth
The adult human body has 32 teeth.
The eight chisel-like incisors at the front bite food. The four pointed canines tear and rip it. The eight premolars and twelve molars at the back of the mouth are flattened to crush and chew it. Before the adult teeth grow the body has a first or milk set of 20 teeth. These begin to grow soon after birth, and are replaced by the adult teeth from the age of about six or seven years.
