I had 3 crowns cemented two weeks ago. They were recommended by my dentist in order to strengthen 3 teeth that had large 20 year old amalgam fillings that needed to be replaced but were too big to fill and crowns were recommended.
Since they started working on my teeth, the crown prep, impressions, temporary crowns, permanent crown cementation, the total work lasted 6 weeks. For the entire 6 weeks, since the beginning of the process, I have had severe dry mouth, a sore/burning tongue, and tingling/numbing feeling on the side of my mouth with the crowns. I was worried I might be allergic to some dental material being used but the dentist insists it can’t be an allergic reaction since there are no other allergy symptoms occurring. I even went for bloodwork with my primary care doctor to see if anything else could be causing the dry mouth but all bloodwork came back fine.
Is it possible that my body is rejecting the crowns, can I be allergic to some material, or is it completely unrelated? I just can’t figure out what’s causing the dry mouth that started as soon as they started working on my mouth. The dry mouth is also making it hard for me to adjust to the feeling of the new crowns because my cheeks and tongue keep sticking to them and adding to the foreign feeling in my mouth. I am so miserable.
Any advice would be appreciated.

I don’t know where your dentist gets this idea, “it can’t be an allergic reaction because there are no other allergy symptoms.” There are varying intensities of allergic reactions with a variety of symptoms. With what you’re experiencing, it certainly sounds to me like an allergic reaction is indeed a possibility. But I can understand why your dentist would want to be in denial over that possibility because the solution, if you are allergic to anything in the crowns, would be to replace the crowns, maybe at your dentist’s expense. Now I’m not saying that what you’re experiencing is for sure an allergic reaction. I’m saying that is a possibility that should be checked out.
Here’s what I would do first—find out what these crowns are made of. You didn’t say anything about what type of crowns they are. If there is any metal in them, that’s where I would start. If there is, ask your dentist for a copy of what is called the identalloy certificate. This is a certificate that dental laboratories are required to provide dentists that lists the exact composition of any metallic alloys used in any dental restoration they make for the dentist. If there is any nickel in the metal, that is a prime candidate for an allergic reaction. Other possible metals that could be causing a sensitivity reaction could be beryllium or chromium. If the crown is metal-free all ceramic, a sensitivity reaction would be very rare, but I wouldn’t totally cross it off.
If you run into any roadblocks with this, I would get a referral to an allergist.
I would also add that it’s possible that the condition in your mouth is stress related (i.e. burning mouth syndrome). Since you had this reaction from the beginning of the work before the crowns were put into your mouth, that could be an explanation. If nothing else seems to provide an adequate explanation, maybe an allergist would be able to help you figure out if burning mouth syndrome is a contributing factor.
(Please see the comments below where I learned from Sandra’s initial response that the crowns were metal-free zirconia, and then 5 months later, where Sandra discovered that this was not an allergy at all but burning mouth syndrome, very possibly triggered by the stress of the dental work.)
