The only one that I know of is Dr. Williams (and I love his assistant Michael) at Monarch Dental on Mockingbird. He's not really holistic, but he was WONDERFUL and he put cloves in my mouth when he cleaned it (I had my teeth pulled). I thought that was weird...cloves! lol So undentist like. He was also very supportive of my breastfeeding. I don't know if he does pediatric dental work, but he's worth a try if you can't find anyone who actually is a holistic dentist. I love him! I have never, ever had a good dentist experience until then.
