I've got 28 teeth. My wisdom teeth came through at age 18-ish, then I have 3 more molars (on each side top and bottom), then a canine, then 2 incisors at the front. Totalling 28. But I've just read that adults generally have 32. Why am I missing some teeth? A diagram shows 4 molars, not 3. I have no gaps and have never had any teeth removed!
