Answer 2

• Premolars Premolars, or bicuspids, are used for chewing and grinding food. Adults have four premolars on each side of their mouths — two on the upper and two on the lower jaw. There are no primary premolars; the first premolars appear around age 10, with the second premolars arriving about a year later.
