The awful pains..

I'm not talking about back pain this time, even worse.. tooth pain. I lack dental insurance and have let it go on for so long I'm in extreme pain.. I'm not sure how I'll pay for it but most importantly will it be safe for my little girl?? I'm 34 weeks along but this tooth has to get taken care of. I can hardly sleep or eat. I'm just so worried about harming her while I'm at the dentist. Can someone give me some insight or even advice on what I should do??
