Yes, I believe mercury can be associated with discolored teeth in some people.

I used to have perfectly white teeth, in fact, I often received compliments about it. After I entered stage 3 mercury toxicity, they quickly began turning yellow and have stayed that way every since. Now that I'm 5 years post removal, they haven't changed a bit.

As soon as I find my whitening kit I received from Dr. Behm and immediately packed and moved to the north, I will have white teeth again.
