I know there have been many other posts about this, but now it's our turn

My almost 4 year old is going to need to fill in a few cavities. First of all, I feel SO guilty. I know some people are just more prone to them, and I swear she is on the low end of consuming sweet/treats compared to the "average kid". The only thing she does get are gummy vitamins. We always brush her teeth after she's done, I make her drink water after eating anything, etc. So anyway, I just feel horrible still.

I just need again, all of your experiences. Currently, the course her dentist suggest is to make a few 1 hour appointments where he'll give nitrous and just try to get as much done as possible for however long she complies. At her last dentist visit she pretty much complied the whole way (but she did cry at some point). And if she freaks the heck out and won't let him do anything, then he suggests to do a mild sedation with a drink (so not going under), but he def hopes to just be able to do it a bit at a time without anything.

I am a wreck between feeling nervous about whether she'd be able to get through this, and also feeling guilty for not doing more
