that would be a dream come true... most (all?) dentists are doing unnecessary x-rays that are a health hazard and this would of course help with that...

If you're worried about that, be sure to wear a hat when you walk outside. Also don't ever fly.

Just yesterday I saw a documentary on the dangers of atomic radiation, and one of the numbers I remember is that the dose of radiation from a dental x-ray is less than the average daily dose of background radiation. So, entirely negligible unless you're getting a dental x-ray every week or more often.

  You are probably talking about the low radiation bite-wing digital x-rays... But some type of dental X-rays have orders of magnitude more radiations, like the Panoramic X-rays (those are very common in dental offices) or the much worst Cone-beam computed tomography (3D). I agree that there probably isn't much risk but they give them out like candies.

    I checked Wikipedia for the different types, and apparently I had a panoramic X-ray made last year. A quick googling finds [1] which puts the maximum dose for X-rays at 0.17 mSv. Wikipedia [2] puts the average background radiation around the world at 3 mSv per year, or 0.082 mSv per day. So while 170 mSv is indeed "orders of magnitude more radiation" than an X-ray of a single tooth, it's still roughly in the order of magnitude I estimated (around a day's worth of background radiation).

      Next time you go to the dentist, try to ask the person taking the x-rays what radiation setting they used or how much radiations you will be getting from the x-rays... in my experience, they don't know... Also ask them why they cover your torso with lead but not your brain... Also, I think that you confused some units and you forgot to include link #2 ...
