I had all my amalgams replaced 5 months ago. Also replaced 4 metal crowns on root canal teeth to metal free crowns.
I don't know what else to think...it could all be related to mercury...

You can have an infection in a tooth for years without any pus or swelling or any signs of the infection on x ray.If a tooth hurts for a long time, it is probably infected.
