Cool Teeth Whitening 4 Trays in 2 Storage Cases Custom DIY Fit Upper and Lower Tooth Bleaching Gel Thermoform Moldable Mouth Guards

The instruction say keep in warm water for 3 to 5 seconds but they need to be laced in longer - they moulded to my mouth/ teeth perfectly

Good, easy to use

I picked up these moldable teeth whitening trays to use with my Opalescence gel, and I’m really happy with them. The trays were easy to mold and shape to my bite, and they held their form nicely once cooled. They feel comfortable in my mouth without pinching or shifting, which made the whitening process much more pleasant than some one-size-fits-all trays I’ve tried before. I like that this set comes with four trays plus two retainer cases so I always have clean backups ready to go. The trays fit the whitening gel perfectly and create a good seal so the gel stays in place without leaking everywhere. After using them consistently for a couple of weeks, I definitely noticed my teeth looking brighter and more even in tone. Nothing painful or irritating happened, and my gums felt fine throughout the process. Overall, these trays are great quality for the price and work really well with Opalescence gel. Easy to use, comfortable to wear, and a great complement to my whitening routine!

The product is not as described in the photo at all. It is really thick and bulky- making it really uncomfortable to sleep with. It is not tight enough to your teeth so the gel does not sit close enough to work and it doesn’t stay in the tray. When I contacted the email they provided they were prepared to offer me a full refund until they found out I was in the UK which they apparently don’t supply to??? When I contacted the seller directly on Amazon they offered a partial refund. Honestly really disappointed.

I am absolutely thrilled with the Moldable and Trimmable Teeth Whitening Tray Set! This innovative product allows you to create a custom fit using just hot water, making it incredibly easy and convenient to achieve that dazzling smile. The BPA-free material gives me peace of mind while using my favorite whitening gel, and the complete set comes with two hygienic dental trays and two travel cases—perfect for on-the-go whitening! These high-quality trays mold in just 10 seconds, providing a snug fit that's specifically designed for adults. I love that they are compatible with Opalescence whitening gel, ensuring effective results right at home. Plus, they are odorless and comfortable to wear, which is a huge plus during the whitening process! What’s even better is that the trays are reusable, making them both practical and economical. With the included retainer cases featuring air vent holes, I can maintain hygiene while allowing my trays to dry thoroughly. This set really delivers on its promise of a brighter, whiter smile! If you're looking for an effective and easy teeth whitening solution, I highly recommend this tray set—it's truly a game changer!
