Most adults have 32 permanent teeth in their mouth, which include 8 incisors, 4 canines, 8 premolars, and 12 molars (including 4 wisdom teeth)
. Children typically have 20 primary (baby) teeth, which eventually fall out and are replaced by the permanent set
. The 32 adult teeth are distributed evenly between the upper and lower jaws, with 16 teeth in each jaw
. Wisdom teeth, or third molars, often erupt between ages 17 and 25 but may be absent or removed due to lack of space or other issues
. Thus, while the full adult set is 32 teeth, some adults may have fewer if wisdom teeth are missing or extracted
