I've been using OralB Minute Fluoride Foam (1.23% fluoride) nightly for over 2 years now. I'm happy with it, my teeth are holding up, but my dentist wants me to use the foam less often. He says 2x per week is all I need. He's a good general practice dentist but he has no experience with oral cancer patients. (I learned about the minute foam from this forum while I was in treatment. I had to insist that my dentist get it for me as the fluoride toothpaste he told me to keep in overnight caused my gums to bleed.)

How frequently do other people use fluoride? Is there any reason to reduce the usage over time?

Thanks,
