I just had some teeth X-rays at a pretty regular dental clinic here in Taiwan. They were showing me the results and explaning what they have found. I was totally amazed how thing that look super-light tiny shadows for me at one place they say "we must check", while elsewhere they were "nothing". What you see totally depends on the expertise you have and I think it wouldn't be hard at all to spot things that for us outsiders are just "maybe a little bit lighter".
