I have already done this and it does work miracles. I have gotten whitening trays from the dentist before but lost them. (They were taken out of my bag at the airport during a random check and never put back in….a couple hundred $$ down the drain. Thank you Burbank, CA.)
So I made these trays and used the rest of my “expensive dentist whitening stuff.” I have not tried the cheap whitening gel in the video but I plan on it. Let me know what you think!
