Does Unvisalign Contain Anything That Would Cause an Allergic Reaction? I have asthma and I am very allergic. I understand that visalign was sent a letter by the FDA concerning reactions. Could it be the trays or medication that is used to prevent infections in the use of the trays? Thanks

Allergies with Invisalign
As I understand that it is very rare to have an allergy to the aligner trays, I have had one patient that had an allergy to the trays. Her gums, lips and cheeks swelled up slightly and she had redness and itchiness. You may want to get a sample of a tray from an Invisalign provider and see an allergist to determine whether you have an allergy to the aligner prior to any treatment.
Invisalign trays are plastic
The material used for the aligners (or trays) with Invisalign is a resin polymer, or plastic. While I have yet to see someone exhibit an allergic reaction, it certainly IS possible (never say never). To be safe, traditional brackets and wires can be used.
Invisalign and allergy
Invisalign aligner trays are made from plastic. As such it is possible (but unlikely) that any individual could be allergic to them. If you have a known allergy to plastic or acrylic you may wish to discuss this with your orthodontist before starting Invisalign treatment. It is my understanding that the FDA reprimanded Align for not reporting known allergic reactions to their product in a timely manner. This does not mean that Invisalign aligners are highly allergenic, and in fact the incidence of severe allergic reactions to the aligner plastic is low.
