Question:
Allergy to crown cements: Highly allergic reaction after removing two old silver filling replacing with crowns and glue.
Allergy tests sent in from Canada found allergic to all arcylates, the cement was hema 2 meth- Methal arcylates. Do they have glue or cement material free of all arcylates? I have two crowns that were cemented in 4 years ago and had the reaction.
Had to take steriods for a long time. I seem ok now. Do they need to remove them and use another glue? And finally why do they use acryaltes when so many people are allergic to them? Please help me.
The dentists that I have tried say they can't find the answer and won't help ... Visitor from FL
Answer:
I am sorry to say that I know nothing of allergies to the cements that you are mentioning.
I do know that we used to use a cement called zinc phosphate when I was in dental school. I'm not sure of the makeup of this, but think it is too old to contain the methyl acrylates that the new cements contain. I am pretty sure that it is still available.
You might look for a homeopathic dentist in your area. If you can locate this cement through a dentist, you could take it to an allergist to perform skin tests and see if you react to it. A crude method of seeing sensitivity is to put a patch of the suspected substance with a bandage to your hand for 24 hours and see if you develop a reaction.
I'm not sure this will help you, but have not seen allergies to cements. Have you consulted an allergist? They may have seen other patients with this problem.
