If you need to get your wisdom teeth removed, it should be safe to do if necessary. They won't be able to put you out (general anesthesia) due to risk during your pregnancy but if it needs to be done, it needs to be done. Your dentist or oral surgeon should coordinate with your OB/GYN and figure out whens the best time to do it, whether that be during the pregnancy or afterwards
Yeah. I've had a miscarriage and an ectopic before.
High risk pregnancy? I would check with your medical doctor before you have what could turn out to be a surgical extraction. If he or she gives the ok, then you can let the dentist that you will be seeing know that you're clear for dental work.
