Clare, i like the idea of the mercury vapour machine that essawy uses, but he doesnt use Diamondlite which is the safest material to use in the mouth, i only had my amalgams done recently with white composites but they are not safe and i dont want any health problems in the future, so i have decided to do them again. If i had the money i would initially go to this dentist for checking for vapours and removing the fillings i have and i would ask if he could put temporary fillings in, then go to Austin for diamondlite, but i cant keep paying out. Essawy is a great dentist, but he just doesn.t use diamondlite, shame.
