Adults typically have 32 teeth. This includes 8 incisors (4 upper and 4 lower), 4 canines (2 upper and 2 lower), 8 premolars (4 upper and 4 lower), and 12 molars (including 4 wisdom teeth, also known as third molars). However, some individuals may have fewer teeth due to various reasons such as extraction or congenital absence.
