Re: how accurate is this info?
i'm pretty sure i know which site you're referring to, and what you've written is true. there is no training to become a "TMJD specialist". health professionals haven't even agreed on what to call TMJ problems - some use TMD, TMJ, TMJD, etc.
what i got out of that site is that they want to warn patients to not be overly trusing of so-called professionals. it's up to us, the patient, to research various treatments, get the pros and cons, associated risks, and make the decision ourselves about what to do.
i do think, tho, that it is overly simplistic of that site to say that nothing works because that leaves us nowhere - we cannot *not* treat our problems. there are risks and things haven't been researched properly, but it's also important to realize that there is a lot of politics going on behind the scenes between various types of treatments.
