Has anyone had major dental work done wile pregnant?

So I have an infection two lower jaw molars from root canals that didn't fix the problem. So now I have to do and extraction on the two molars that involve drilling into the bone and then putting bone extract( power stuff) in and sealing it with membrane to put in implants later. So basically pretty painful stuff. I have been holding off on it for a while now. Actually had it with 1 year son. Should have had it done right after didn't. It didn't bother me too much because there was no pain,until now because of receding gum line, the smell, and the tender gums.

Anyways the medications I am concerned about are the Ibuprofen because I do have stomach sensitivity and not sure if the is good for main stomach. And the major one is Norco 5. According to only research it classfied as class C drugs, not well tested on pregnant women, but only some animals tested don't have problem with baby.( Has me worried) My OB was not very helpful, he didn't even have Norco 5 on his list and just said it should be fine. My OB and dentist just push back and say it's up to the other. I just want to know if anyone has any experience with this and advice. I am just worried about how it would affect my baby. I am 17 weeks pregnant.
