essix retainers and heat

[litenight]

Hello guys! So I wanted to know what temperatures are generally required to warp or ruin essix retainers. I am asking this because I accidentally left my retainers right beside the cooling fan of my laptop. The retainers were in their case. When I put them back on they seemed to fit properly, but still I am worried I might have ruined them.

Yeah you've probably ruined them, after all they don't fit now and have visible damage.

Just kidding it's plastic, chill.

In general, you should keep them away from heat sources (out of hot sun in your car or on a window ledge). I don't know what temperature it would take to warp them, but I think that normal situations would be OK. Think about how intense it has to be in a microwave to warp plastic!
