I had my wisdom teeth out at age 19. Didn't develop Crohn's until age 31 but coincidently just after I had tubal ligation surgery. My theory is that the intrusion into my abdomen & surgical clips that were left set off my immune system. After 6 months of low grade symptoms I was found to have intussception & had a small bowel resection. That seemed to really set off my Crohn's & it was uncontrollable until I was put on Remicade. That has worked well for over 3 years now.
