My 4 yo is scheduled for a small filling on one of her back molars. I haven't told her that she's having it done (at the advice of the dentist). She is pretty sensitive and fearful of new experiences. I'm really worried about how she'll handle all of it. Any tips from parents who have gone through it?

One thing I plan on doing is picking up one of the things they put over her nose for the gas so we can "play" with it at home beforehand.
