I have done lots of bleaching in my day. I still have the old Almore
Monarch II bleaching instrument from the days of using superoxol heated with
this device. [Want to buy it? :-) ] Many vital and non-vital bleaching
cases. Even more cases done with custom fitted trays and take home
chemistry. I have never seen amalgam discolor from it.
