Can i safely put tooth whitening gel in my plastic retainer ?

Question

i got a tooth whitening kit online http://www.amazon.com/Complete-Professional-Whitening-Optimized-Formula/dp/B000O3SHF8 ....it came with moldable trays that i dip into boiling water and then mold to my teeth....instead of using these trays can i use my plastic retainer to put the gel in?

Answer 1

If the retainer covers the front of your teeth, like Invisalign, then it would work.
