Teeth Whitening Trays for Gel 4 Pc Moldable Flexible Guards with 2 Cases | Compatible with Opalescence Gel Custom Trim to Fit Reusable Tooth Bleaching Carbamide Peroxide Remineralization Enamel Safe

I have been using these moldable trays with my whitening gel for 10 days, and I am very satisfied with the results. They mold easily, and the material, although thin, is durable and comfortable to use. I follow the instructions for my gel, using the trays for 30 minutes per session, and it works very well. One tip: be careful with the water temperature when molding them. It should be hot but not boiling to avoid deforming them. If you follow the instructions properly, there won't be any issues. At first, I used too much gel, and it spilled a bit onto my gums, but by adjusting the right amount, I no longer had any problems. These days, I notice my teeth are whiter and have a more even tone. I like that they are reusable and come with 4 trays and 2 cases for storage, which makes them very practical. Although it doesn't come with the gel included, I use my own whitening gel, and it works perfectly. I keep my teeth white and healthy, and I go to my dentist for a professional cleaning every 3 months. With these trays and my gel, I manage to keep my teeth as white as possible between visits.

Please are good for using teeth whitening Gel. They do mold to your teeth and you can redo it if you mess up.

These trays are okay for the price. I purchased them primarily to use as a night guard rather than for teeth whitening, and they serve that purpose reasonably well. The molding process was fairly simple. I followed the instructions carefully and even used a thermometer to make sure the water temperature was correct, which helped. The trays molded to my teeth, but I wish they fit a little tighter and more securely. They don't feel quite as custom-fitted as I had hoped. That said, they're inexpensive and functional. While they're not perfect, I would probably buy them again because they offer decent value for the price.

I’m very pleased with the quality of the dental trays. They were easy to mold to your teeth and were comfortable to wear. I slightly messed up my first attempt to fit my tray and the second one turned out perfect and molded to my teeth. Problem is I was used to the hard plastic dental trays and when I filled them with whitening gel I bit down too much and cut thru my tray. The instructions said to call for replacements if you had any issues. I emailed them and Kevin, the owner, messaged me back immediately and sent some replacement trays for free. You couldn’t ask for any better customer service! I think people will be very satisfied with these trays and they will do a good job of holding the whitening gel in a comfortable way.

In 2015 I bought a whitening kit that contained syringes filled with 35% carbamide peroxide that burned like crazy. As I recall, I wasn't seeing noticeable results after using two or three tubes, so I decided it wasn't worth the pain and threw out the rest. Because of that experience, I was prepared for significant burning from this 44% carbamide peroxide product. Therefore I was surprised to find no burning at all, not even when used twice as long as instructed. NONE. I had to hot-dip the trays twice, and the second time one of them deformed and couldn't be fixed. I emailed the company who immediately sent a replacement set. Later I had a product question so I sent another email - the seller did not respond. I began cautiously with the recommended 15-minute treatments, which I continued with through #18. I was seeing little, if any results, so from #19 thru #30 I did 30 minutes each. Still no progress. I must have been using the gel more sparingly than intended, because I got 30 treatments out of 4 syringes. I was ready to give up but decided to open the last tube anyway. I did two treatments of 15 minutes each, and then tossed the remainder in the trash. I don't think I received any benefit at all - my teeth aren't any whiter. They were on the darker side of the chart when I began, so plenty of room for improvement. But when I finished, my teeth seemed to be in the same spot on the chart - possibly a shade whiter. I don't smoke, don't drink a lot of coffee and not much cola. My teeth are in fair shape and had been cleaned a few months before the kit arrived. Because there was zero burning sensation and little to no whitening, I have serious doubts the product contained the stated amount of peroxide. It was certainly a waste of my time and money.

Whitened my teeth at least 3 shades ! Will purchase again!

Easy to use I had gotten some whiten serum to start whitening my teeth but did not have any trays so I didn’t get a chance to use it so I went ahead and order these it came with more than one tray that’s reusable so I was able to give my husband one, they fit to all mouths making it foldable to use on any teeth has a protective case to store and protect when we aren’t using them

Not easy to mold. Really not ideal for whitening product, more like a mouth guard, less like a tray

Whitening works well however, trays are thick and do not mould to our teeth. You use more whitening gel. Very average

Pésimos y tarda mucho

Disappointed they do not mould properly to your teeth do not recommend

Tel que je m'y attendais

Terrible, nothing like end result in advert. Bought 2 double sets and not one is adequate to use for whitening gel.
