I'm sorry RoryAsk to see an intraoral camera or the radiograph next time. They will be happy to show you the evidence of decay clinically. And remember that a cavity is about 20% smaller on an x-ray in comparison to when you get in there. If you don't believe them then don't get the filling/crown/onlay. Then in a couple to many years see what happens and if they were right.

I did ask him to show me the cavities and he said they cannot be seen on an x-ray because they're so small...and he said that on the introral camera that they will simply look like stains...
Once again, I did not mean anything by what I said...and I never said that I believed it...I was just trying to show Ilovetosmile232 that it could possibly happen...If it actually did or did not happen, I am not too sure...As someone else said, it's only one side of the story...The person may actually have had bad credit, or did something that caused the ortho to doubt them...or the ortho may have had bad experiences in the past with persons not paying the full amount and disappearing...
I too believe everything I read on the internet or hear from people. It is not human nature to ever stretch the truth or change details from a story, especially if it didn't go as the person wanted or originally planned.
I know now what they mean when people say that their face got hot from embarassment, because mine sure did... I'm sorry...
