Oh my gosh, YES, it does hurt her. Teeth, once they have been ground are SUPER sensitive and HURT. Trust me, I'm telling you this from my own experience. The poor little thing is hurting. You need to get her to a dentist ASAP, please!!! Also file a complaint againt the dentist with Medi-cal. Yes, you can do this. I've done if for my dad before. They may be able to help you see a different dentist if you still have the medi-cal. They need to know this dentist does shabby work and then claimed they couldn't fix the problem. And there are other programs
besides medi-cal you may qualify for. In cali I think it's through Healthy Children or something like that. Very inexpensive!!!
