Can't go in there without them trying to tell me to put a chunk of plastic in my mouth to stop the grinding. (As described in TFA).
Described as a diagnostic by them, a problem we discovered in you, mr porcupine... But strangely recommended to every other single person I've talked to. Very scientific.
Paid for by insurance of course.
I did this once years ago and the mouth guard was both annoying and disgusting. Never again.
Everything is priced exactly the maximum that your insurance provider will pay.
When I was (and am) contracting and didn't have insurance anymore... the plastic-pushing stopped, remarkably.
Regular cleaning and fillings are important. But so much of their business seems to have degraded into orthotics for the face.
