The Central Incisors are often referred to as the "two front teeth" and these are usually the first adult teeth to appear.  The Lateral Incisors are located just to the left and right.  The Incisors are primary used for biting.

The Canine teeth are very pointed and sharp and appear to the left and the right of the Incisors.  The canines are primarily used to tear.

The first and second pre-molars are located after the Canines and the first and second molars are located after the pre-molars.  The pre-molars and molars are teeth we use for grinding and chewing.

The wisdom teeth may or may not appear in the healthy adult and are located after the molars.
