I am 3 weeks from being done with my Invisalign Express. I have been searching the archives for info on the "safest" material for retainers. I found some discussion on different plastics that Invisalign can use when they make the aligners.
For the 20 weeks that I had aligners, I took a chance on whether the plastic was poisoning me. But I want a clearly safe choice for the retainers.
What I need now is - what is safest for use in my mouth for "the rest of my life". Has anyone researched the materials that make up the different choices in retainers? Thanks!
What type of retainer do you suggest?
