Bex, I have emailed this man, but so far, have received nothing back. Thanks for the info though. Maybe the other guy was right. Maybe Biodent is no longer in business and they are no longer making Diamondlite. I had to cancel my daughter's appt. because everything is up in the air. My 'holistic" dentist did use Diamondlite on me, but he usually uses Heliomolar. I looked up Heliomolar on the web and they proudly proclaim about how much fluoride is in their product - like it is an asset! Anyway, Bex, what info did this fellow give you re Diamondlite? Thanks.
