I'm pretty conflicted about the "advice" to make her stop, since it seems like the emotional consequences (at this stage) are worse than the dental ones. (She was pretty upset about being told she had to give up the habit. And she seriously never does it during the day unless she's ill or extremely tired.)
You're dentist is nuts- go find a different dentist.
I've had children in my preschool classes lose teeth as early as 4 and a half. One of my preschool girls just went off to kindergarten this September with 4 adult teeth and two loose ones. It's a little young, but normal. I've also known children who have not lost any teeth until almost 8, myself included. Also normal, though a bit late. My own children both lost their first ones at 6 1/2, my niece at almost 5 1/2 (naturally, that is- she lost one otherwise at two).
