I would wait till second trimester..I'm 8months preggo and have had three teeth pulled a wisdom tooth and two molars..all in second trimester! Ur dentist should control the infection w/antibiotics until ur secobd trimester! As for pain after they gave me Tylenol 3!
I think you should be fine.
But confirmation contact your dentist and explain that you are pregnant.
It may be able to be saved rather than pulled out.
Best wishes enjoy your pregnancy.
Speak to your obgyn before going to the dentist...
