Question:
Do overnight teeth whiteners harm plastic retainers?
I'm starting to use one of those brush on over-night teeth whiteners (it comes in a little bottle like a nail polish bottle) that you just apply to your teeth and sleep with. however, i still wear a clear plastic retainer (NOT the wire one.. the one that looks like invisalign). i'm afriad that if i put on the retainer over my teeth with the whitening stuff on that it will eat away at my retainer? i'd like to think that what i'm putting on my teeth isn't like, toxic enough to eat away at a retainer but you never know. i don't want to ruin my retainer because its $500 to replace. So if anyone has experience with this or knows about it, please let me know.
Answers:
Plastic retainers are usually made from the same kind of material as custom-fit overnight bleaching trays (acrylic plastic, though the bleaching tray ones are thinner-gauge and softer).
The overnight teeth whiteners shouldn't harm the retainers.
