I just picked up some CariFree CTx4 Gel 1100. It has Nanohydroxyapatite, Fluoride, and Xylitol.

I'm actually quite annoyed that none of the half dozen dentists I've seen in the last 15 years have mentioned Nanohydroxyapatite as a compliment to fluoride.

Thanks for the recommendation, I had never heard of it. And I had the same experience in regards to the hydroxyapatite. No dentists told me, I just discovered it on pubmed and then went googling like crazy.
