How many premolar teeth does an adult human have?
Answer & explanation
Correct answer: option 2
The correct answer is Option (2) → 8
An adult has 32 permanent teeth: in each half of each jaw there are 2 incisors, 1 canine, 2 premolars and 3 molars. With four such halves, the number of premolars is \(2\times4=8\). Milk teeth have no premolars.
