Hi Torrie
It isn't only the teeth where I removed the Amalgam that are sensitive, it is all of them. Well, maybe the ones that have been worked at are a more sensitive than the others. There is also one tooth that didn't have Amalgam but had a cavitation, and some cement attached because of the Maryland that got unbonded (I don't know if you remember, I am going to put a new Maryland all on-metallic as you suggested, at the end of the month). Next time I go to the dentist I'll ask him the name of the material he used. He said he had used it a lot with the other patients with no problems.
I dropped my salt toothpaste for simple natural soap, it feels good when i use it, and this is the reason why I thought that it is an acidic local condition as the soap feels good and it is alkaline.
