Just received my powder about two weeks ago and I am using it three times a week (basically every other day). Hearing about hydroxyapetite made me more curious and as to why Dentists do not even bring up this in any visit - They love to recommend toothbrushes, toothpaste, flossers, etc but never once has my dentist ever mentioned this being out there for a try. This makes me wonder if they are intentionally hiding it from their patients.
I am not crazy about the taste as it feels like it is 'burning' a bit and then it goes away but i will continue to use it because i want to have something that i control in my oral hygiene rather than depending on a dentist for cleaning, filling cavities, etc etc. Next visit I want to inform him of what i discovered on my own with no guidance from him or his team. Time will tell
