Couldn’t be the mercury fillings- Our very own US FDA says it’s safe!
Some disagree.

I believe there are many many people affected by dental allergies from crown materials, filling materials, cements and adhesives.
There doesn't seem to be very much information on the net about it though which is very odd...
I had a metal crown that I believe I was allergic to. It was really irritating my mouth for almost a year. I never dreamed they'd actually put anything that bad in a person's mouth! Dentist kept saying no, not an allergy, but it fits because I can't wear jewelry.
I finally got it replaced a couple of months ago with a porcelain crown. It is healing very slowly. I can finally move my tongue around and brush my teeth without crying. I think I had some kind of problem with the novocaine injection site too that messed up the nerves too.
I'm looking for another dentist, but maybe these are just more weird changes from quitting smoking. After I quit smoking, I became allergic to more things that never bothered me before and get tonsillitis frequently.
I think smoking might cover up other problems.
I had my first amalgam fillings at 16 years of age. I am now 71 and feeling fine. Still got my own teeth.
