All New and Improved 2 Sets Modable Bleaching Trays. Boil and Bites Mouth Pieces By Touch of White Smile

Comment: I had almost no problems getting these trays to work. And the problems I did have were user error, not product problems.

I did have to leave them in the hot water* a lot longer than the 2 -3 seconds the directions stated. The only problem I had was with biting down and sucking out the air correctly. Thankfully there are 4 trays. I messed up 2 and am wearing the other 2 right now.

I had to do the top in 2 tries being very careful to not over heat the tray each time. You can tell when it softens up and is ready to mold. Once I got my teeth properly in the tray, I bit down pretty hard, sucked out all the air and excess water that I could and used my fingers to mold the tray to my teeth.

The first top tray impression was pretty good but after reheating it and finessing the fit a bit more, it was a fantastic. I could see the impression of my teeth so good that I was able to trim away the excess with my Tonic scissors. I also checked my trimming in a small mirror. The tray being clear, you can see your gum line and where there is excess tray.

The bottom tray was a little more problematic. Some of my bottom teeth are very crooked and it was hard to get them into the tray and then I had to draw trim lines on it (used an ink pen, yeah, yucky so sue me but it worked) to trim them down. But I didn't have to heat up twice because the first impression was pretty darned good.

I probably will go back and do a little more fine tuning on my trimming with a jewelry file.

Even with the extra fine tuning I did, this isn't that difficult; it just takes a little patience and concentration. Without the customizing, this is the exact same procedure as you would use with a bleaching kit that comes with boil and bite trays. Also, this is only the third time that I have ever done this, and the first where I actually went back and trimmed the excess to get more of a custom dental tray fit. So for the money I paid for these (1.99 + 4.5 S/H), I am extremely pleased.

*I boiled the water in my electric kettle until it came to a full boil then poured into a small Pyrex bowl, just big enough and deep enough to cover the tray and dunked the tray in right away. Once I was happy with the impression, I put the tray in ice water for awhile to set it.)

Comment: DO NOT BUY THIS ITEM!!!!!!!!!!! Trays did not mold!!!!!!! The only impression that could be made looked mile a grain of rice! WHAT A RIP OFF!!!!!!!!!
