Unfortunately I have an anecdote, but is also a concern.
I had a tooth pulled. Could have been a root canal, but whatever. (Insert sob story)
The real problem was that this dentistry was quietly affiliated to the local university's dental school. Many of the students end up here. The problem, is that the dentistry IS NOT UPFRONT this is a teaching business, and not actual professionals.
I found it out when I was digging through unrelated records in GIS, and found they were legally registered as a school. Dug deeper, and they're basically misrepresenting and lying to the public.
So yeah, keep this scam in mind as well. (I call it a scam cause I wasn't getting student rates, and they did their damndest to hide that.)
