How many molars does adult have?

I guess there are 20 molars in total.8 premolars and 12 molars the front teeth are incisors and canines.

First pre-molar, second pre-molar, first molar, the second molar, the third molar assuming all wisdom teeth are present so that's 5 molars all together. The answer is 12 if all wisdom teeth have erupted.
