Can you get cavities filled while pregnant??

You can but I found not all dentist are willing to preform during pregnancy. I found one and my doc had to complete a Dma-635 form - authorization. I'm getting a teeth removed though.

Yes. And it’s the perfect time since you are still in the 2nd trimester.

Yes I did during my earlier weeks, but I choose to opt out of the X-rays

Yes! But the dentist will mostly likely want a paper giving them the ok from your OBGYN. That's what I had too do.
