Adult humans typically have 32 teeth, including 8 incisors, 4 canines, 8 premolars, and 12 molars (including 4 wisdom teeth).
These teeth are arranged in the upper and lower jaws and are used for biting, chewing, and grinding food. However, it's worth noting that not everyone develops all four wisdom teeth, and some people may need to have one or more of their teeth extracted due to dental problems or other issues. Additionally, some people may have extra teeth, a condition known as hyperdontia, or may be missing some teeth due to genetics, trauma, or other factors.
