Lori:
I've had those 'entertaining' doctors and dentists too. I found their shenanigans got old, fast and their bills were sometimes higher than a more conventional doctor or dentist. I'm sure your dentist is capable and intelligent but the respirator routine just seems way over the top, as if he were going to die from possible contact with a very minute amount of mercury in your filling That is simply ridiculous. However, if you found it entertaining, who am I to complain? Obviously, your sense of humor surpasses mine and I respect that but I couldn't see this dentist and hygienist enter the room wearing respirators to extract an old almalgam filling and not wonder about their connection to reality, not to mention their attention to professional literature that has dealt with the mercury issue and found it mostly devoid of substance. Still, if you're happy with this dentist and find him trustworthy, as you clearly do, that's great. I was only offering my would-be reaction to a dentist wearing a full-blown respirator to show his fear of a tiny old filling that probably has less mercury in it than the seafood dinner he had last week. But thats just me.

I claim no expertise in dental or BAHA technology but your dentist sounds like he misunderstands how the BAHA device operates. I would have asked him what he meant. You can also consult your doctor, as Lori suggested.
