In addition to choosing the toothpaste, it’s important to use the right brushing technique and schedule, which is critical since toothpaste does the bulk of the work after the physical process of brushing is done: don’t rinse with water (just spit instead) and arrange brushing so that you don’t eat or drink afterwards.
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.
