I visited the University of Alberta's dental school. It's a fabulous facility, by the way. They told me they need patients, and they generally charge their patients some fees, sometimes just for the supplies that have to be used.
If they sign up for the CDCP, they can bill the CDCP, thereby providing themselves with patients and probably increased revenue. This is because at 88% of the fee guides, they'd to be getting significantly more revenue than they're getting directly from the marginalized people who are paying them out of their pockets now.
Might that go some distance in allaying your concerns?
