This is helpful, if scary. Thanks. It does seem unlikely that all 16 teeth would still be screwed up--pain localization failures seem more likely, but Im just going off of my intuition. I'm going back to the same guy who did all of my fillings ASAP to get things checked out again. (I wonder, if some number of my teeth weren't cleaned correctly, does that mean it's ok for me to keep seeing that dentist?)
