An adult human normally has______?
Correct answer: D. 12 molar teeth
- A. 6 molar teeth
- B. 8 molar teeth
- C. 10 molar teeth
- D. 12 molar teeth
Explanation
An adult normally has 12 molars: 3 on each side of the upper jaw and 3 on each side of the lower jaw, including the wisdom teeth. Students may choose 8 because there are 8 premolars, or because wisdom teeth may be absent or removed, but the normal complete dentition has 12 molars.
