No problem in getting your dental work, in fact it's important to stay healthy and infection free So go to the dentist, just make sure that he/she knows that you are pregnant and how far along you are. And get that tooth fixed.

And don't fret about bubba being ok. It's normal to have niggels about bubba's safety, but there are NO BETTER PLACE than where bubba is right now. You body will keep bubba safe and healthy

Happy Healthy Pregnancy
