The crown, or visible part of the tooth, forms before the roots do. Eventually, the 20 primary teeth are replaced by 32 permanent teeth. The primary molars are replaced by permanent premolars (also called bicuspids) and the permanent molars come in behind the primary teeth.

They are followed by the upper two front teeth.
