Unless they are infected or severely impacted and you are having a healthy pregnancy and are in your 2nd trimester do NOT do it! Most dentists will seek a letter of approval from your OB clearing you for dental work. I work in the dental field. Too many risks if its not urgently needed!
You can have x rays. Lol its only risky if your having abdominal x rays, but the radiation obtained with a dental x ray isnt much. It is recommended to only have dental work done in the second trimester. I had my teeth pulled due to an infection and they have to do x rays so they dont leave anything behind etc. I say if they are causing you pain go for it. If not then wait. I did mine soley because of the infection and pain everyday is very stressful!
You have to wait until after because you can't have X rays done and there is a possible risk for infection
Well unless it's an emergency wait. My dentist won't even fill the two tiny cavities I seem to have accrued since my last 6 month check said to come in after I have baby no big deal.
