I’m freaking out!!! So I broke my molar in half when I was pregnant with my son. OB said happens all the time it’s because the baby takes all your vitamins and nutrients. Wasn’t really painful and I didn’t have insurance at the time to get it fixed. Fast forward to now and I have insurance but of course in order to do something about it the dentist said it has to be after my daughter is born. Well I just took a drink of some chocolate milk and my mouth started hurting, I feel where the molar is and it’s GONE. I now have a gaping hole that hurts like no other! I’m scared I’ll get an infection. What should I do?
