Would like some advice from dentists on what to do next: My daughter is 3.5 years old and went to her first appointment because she has some signs of tooth decay. I'm suspicious of dentists as I've been ripped off before for procedures that weren't necessarily required.So X-rays were taken however the dentists can't tell how deep the cavity is until they do the procedure which may result in a crown or root canal. Is that possible? I mean, why waste x-Rays if you can't tell you anything. Also, she's going to lose these teeth anyways, does she really need a root canal?My daughter's dental insurance doesn't kick in until January, I would say the decay is moderate for 4 tooths. You think waiting too January wouldn't make a huge difference? Been quoted up to $2700 depending on the treatment.Any advice appreciated
