From my experience so far, CAMBRA looks like a great way to make a ton of money. You "prescribe" a half-dozen expensive rinses, mints and sprays to every patient who walks through the door, charge them for pH testing, caries cultures, caries "biopsies", GI sealants everywhere, in-office Fl- treatment, diet counseling, caries susceptibility testing, etc...
You do this on any and every patient who walks through the door regardless of actual need, and the best part is if it works, you can claim it's because you're an amazing clinician, and if it fails it's always because of "home care" or "patient compliance."
Yes, there are a few dentists who practice this way. All the ones I've heard of are doing just fine financially.
