Talked to my new dentist and she will be removing the zirconia crowns on Saturday and putting me in temporaries to see if my symptoms subside before putting new crowns on. She's talking about emax crowns but I've been reading of people having the same sensitivity issues with the emax so I might have to end up going with PFM or just porcelain.

Anyone else have any updates?

Whoever told you that is mistaken. e.max flexural strength is up to 500mPa. Zirconia is up to 1400mPa. Huge difference in strength.

Good for you. I had one replaced yesterday and one today. I still have one left. My new dentist wants me to give it a few days before we replace the most recent crown (2-weeks ago). The symptoms began after replacing 2-PFM failing crowns with zirconia 5-weeks ago. The new crown replacement was just one of the many attempts to treat the metal/battery taste. It is also zirconia. If this resolves the issue, I'm leaning toward going back to PFM crowns. I have a lot of them and haven't had any reactions to them.

So what would be a good alternative for molars if we can't tolerate Zirconia?

If you can afford it and don't care about looks, gold is the best.

I gotta say, gold IS the best. I have some gold crowns in the back that have been in for 46 years with NO problems! Everything else has gone to hell in a handbasket, unfortunately......

What would be a second option? PFM? Emax? Porcelain?

Also, is it a bad idea to get gold when you still have many amalgam fillings? I thought it was bad to mix so many metals in the mouth.

We also need to hound our dentists to submit adverse reaction data to whatever database they report to or dentistry in general will continue to deny the existence of allergy to this metal.
I just visited an oral medicine specialist, he says it's probably not the zirconia, it's probably the cement. I don't know. I'm still having the zirconia taken out, Aug 13. Been a long goddam ordeal. More than a year. Maybe there's a lab or something that tests for zirconia sensitivity/allergy?

I'm no dentist but have had loads of work done over the years. My gut feeling it IS the cement, not the zirconia. Good luck

I had the Zirconia taken out about two weeks ago and no luck. Still have the same symptoms. I'm currently in temporaries. I'm thinking it might be an ingredient in the cements that I could be allergic to. But what?
