Subject: allergic reactions to Invisalign materials
I recently had a patient (45 yr old adult female) who complained of medical problems that started around the same time as she started Invisalign tx. The chief complaint was vitamin D deficiency as well as being run down. When I moved her from regular aligners to Invisalign retainers, her symptoms increased to the point she felt her tongue and throat were swollen and very sore. When she removed the retainers she felt much better.
I then transitioned her to a fixed lower retainer and a true Essix retainer made from Ace material from Raintree.
The patient then did some research and found out about the FDA fine that Invisalign paid for not properly notifying the FDA about similar type complaints that Invisalign was aware of.
Does anyone have any similar concerns or complaints from patients?
Here is a note from the patient about what she experienced
