Root canal, really?

So my poor little Megan had some dental work to do. Ok, not just some, 6 cavities. Yes, she goes to the dentist every six months and yes, she brushes her teeth, but obviously not as much as we should. With this last pregnancy, I admit, we really slacked. At her age, we still brushed Catherine's teeth 95% of the time and let her only brush her own teeth a little. We let Megan brush her own teeth way too much and now she had to get them fixed. Because there were so many we opted to have it done at a surgical center where she'd be completely put out, which turned out to be a good thing, because one of those poor little teeth ended up having a root canal. So now she's only 4 and she's had a root canal and has a crown, which she doesn't like. I was in my 30's before my first root canal and I just now had my first crown and I have bad teeth. So now she says it feels weird and she can't eat normal. So, back to mom and dad doing all the brushing for the kids.
