I had my wisdom tooth pulled when I was 16 weeks. Just make sure they know you are pregnant they will just make sure your stomach is well covered with the lead. My dentist had a X-ray machine that just ciricled around my head
Make surw they cover ur belly wit the lead cover. U should be fine I had like 5 cavities and a deep cleaning some in my first trimester in Jan. Good luck I hate the dentist lol
