Hi Dawn.

That's a tricky one. I don't think Austin checks the mouth for remaining mercury with a machine. For removal he uses:

dental dam
oxygen
body covering
face covering
goggles
wet eye patches
suction (I think)

He was trained under Hal Huggins and believes that diamondlite is the safest. He can arrange an appointment immediately with biolab (providing they are open, of course) so long as you ask him for one. It costs £50 for sensitivity test to the diamondlite.

He doesn't check the vapour reading from the fillings, but does check the voltage and removes the fillings in that order, not crossing the centre of the mouth. He uses non-adrenalin injections and as much natural products as possible.

I don't know anything about the testing with a machine. I hope someone else can give you input on that. Did this dentist tell you what he does use so that you can check it out?
