Review on 💎 Pureline Opalescence Whitening Teeth Moldable Bleach Trays - Pack of 3 by Scott Bailey

I know why there are three in the pack. Luckily I only needed one for my upper teeth. After reading the sculpting reviews, I decided to boil water, then remove it from the heat for five minutes, then submerge the tray in water. It definitely didn't work. Even after 30 seconds or more in hot water it never got flexible enough. Then I tried putting it in boiling water. I walked out every five seconds, trying not to walk too long. Still not malleable enough so left it a little longer and it was too much to destroy. I tried the boil method again and really paid attention and pulled them out thinking they might work maybe 10 seconds? I have half glued them to my teeth but I will say they will not be good enough to whiten my teeth. I can see the gaps and the tray won't stay up so I have to bite down on it to keep it in place. Tried a third and overdid it a little like the first but again managed to shape the teeth a little better but still not tight enough. Haven't tried using them for whitening yet and I'm pretty sure just because they don't sit well they won't work, but I'll try. For the price I think that's to be expected.
