Possibly. The number broken drill bits left in patients teeth, is still fairly small. I had to have mine emergency extracted in Australia, so it was only in my head about 7 years.

It is an interesting question. People with more MRI experience than I might have some information.

There was a woman in New York who needed a root canal when she was skiing in France. She had problems when she returned to the US and came back to her dentist. OMG - the dentist in France had drilled all tge way through to her sinus and there was a big wad of filling up there that had to be removed.

Yikes. I am glad for my dentists.
