What are you on about?
Also every once in a while you see some real horror stories of dentists doing unnecessary procedures on sedated patients, and although the extreme cases are absolutely the exception, I always do have to wonder if I actually need the (often expensive) treatments they recommend.
Iirc, a check-up is £22, incl. anything relatively standard they need to do (cleaning, sealing, I think even the cheap non-white or whatever fillings, etc.). Certainly not an amount to be annoyed at the lack of reduction through competition.
In the USA? If so, that's probably moreso a result of the reimbursement structures imposed by dental insurance companies, rather than active collusion among dentists.
Like any profession, dentistry has it share of charlatans:

I've had dental offices that try to sell/bill me for extra cavities (7 at one place!), preventative crowns, sneaking in fluoride treatments and other add-ons to a cleaning, and periodontal cleanings.
In all of these occasions I'd get other opinions, often more than one, and would be told by other dentists that I didn't need these treatments.. I've found that dentists are more variable than car mechanics, meaning that if you go to three dentists you might end up with three different treatment recommendations.
I've also had two hygienists tell me they would never go to a corporate/franchise/national dental chain, after having worked at these places and seeing first hand how they've taken advantage of people, going as far as recommending implants that weren't needed. Based on my experiences I would concur.
They are medical professionals of course, and few are recommending completely nonsense, but it's like, if go to a plastic surgeon... they are probably going to find plastic surgery to perform. Not that it's _wrong_, just that it's really not necessary when you balance in the cost.
I will try Mexico next time.
