There are incisors (8), canines (4), and molars (8), generally smaller versions of the adult or permanent teeth. There are only 20 baby teeth compared to 32 adult teeth. The reason is that the 12 adult molars grow out behind the baby molars, not under them. The 8 baby molars are replaced by the premolars (biscuspid teeth), while the incisors and canines are replaced by their permanent versions.
