Teeth Whitening Trays - BPA Free - Thin Moldable Mouth Trays Form Perfectly to Each Tooth (4 Trays)

Works perfectly. Follow the instructions exactly and you’ll have great results.

I use this at night to keep remineralizing paste on my teeth, and it does a good job. The tray doesn't extend to my very back molars, and maybe that's on purpose since it's meant for whitening, but a little frustrating for my purposes. It feels a little bulky in the mouth, nothing uncomfortable, though.To shape the tray, I heated water in my electric kettle, poured into a coffee mug, and then lowered in the tray, holding it by the tab. Five seconds is the absolute MAXIMUM to leave it in there. I got careless and gave it a few extra seconds, and the edges started collapsing, and I was barely able to unstick them in time and get it shaped to my teeth.

As long as you follow the instructions, the whole instructions it works! Don't worry about it getting to hot in your mouth. Heres my step.Before I put them in my mouth I washed them, then made it a spot comfortable where it will sit and practice like it said in step 1I boiled water in a tea kettle, poured in a small cooking pan - no boilDipped one tray in, counted to 5,pulled straight out to hang "dry" for 2 seconds - inserted on the top and sucked to seal it and used my fingers to get a good grip and held it that way until I felt it start to "harden" or get stiff, you'll feel the difference. The bottom I did kind of mess up cuz I forgot to press my fingers against it, so I redipped it for 3 seconds pulled straight out and dipped back for another 3 seconds but had to make sure the back part didn't fold cuz it will quick. But it worked the 2nd time too.Hope this helps and works for yall too.I would definitely purchase again as it was simple, easy, didn't have any taste or smell like others I've experienced, and loved the redip to save the tray. It helped a lot.

They’re cheap so don’t expect fabulous quality but they’re ok for what you pay. They don’t mold super tight fitting and they’re bulky. Wearing both the top and bottom at the same time and your jaw may become sore. But if you don’t want to spend the hundreds you’re likely to at the dentist office for whitening trays, they’ll work ok.

They are horrible. Material is too think and does not mold well.

These teeth whitening trays are very good, and a good price. They were very simple to mold to my teeth, and what I loved most is how soft and gentle they feel. The gooey-rubbery material is surprisingly comfortable, making them easy to wear without irritation. Definitely a great choice if you're looking for effective and user-friendly trays.

Good product

Harder to make impression that video shows. Did not work well for me.
