## Description

PREFITTING PROCEDURE: Place one tray in your mouth placing on your upper teeth. Practice sucking the air from the tray. This is the procedure you will use when you retrieve the trays from the boiling water to contour the tray to the inside surface of your teeth. Do the same procedure with the other tray with your lower teeth. BOILING WATER: Boil a pan of water. Remove the water from the heat. Place the tray in the hot water by the tab. Leave in water for 3-4 seconds. FITTING THE TRAY:Lift the tray from the water using the tab. Quickly place the tray around the teeth and perform the same sucking procedure as practiced with the prefitting procedure. To avoid gel contact with the sensitive tissues of your mouth, take small scissorsand/or nail clippers and trim your trays on the gingival line (teeth/gum line). NOTE: This product does NOT include gel.

Review: amazing value - I don't write many reviews, but this one was worth the effort. There are many options out there including LED activated trays. Many reviews said they burned their gums and turned them white (with pictures to prove it). Why would anyone need more than this straightforward solution? I had trays done by my dentist many years ago for hundreds of dollars. They worked well Recently they broke apart. These trays were simple to mold and fit just as well. I used less than recommended (only about 0.5 ml or less for both trays) 22% peroxide whitener. No burned gums, and my teeth have gone from noticeably yellow to much whiter in three 30 minute sessions. I can easily go more, but already I have achieved my goals with little effort and less then a week's time. I had no trouble molding them. They didn't stick or cause any issues. Such a great deal. And I was not paid to write this review.
Review: I learned that its worth it to get the dentist made trays! - It was my first experience with these type of trays and at first it was kind of cool to be able to "custom" fit the trays. However that excitement quickly faded. I was lucky to have 3 trays because one of them became too hot and the silicon fused to itself making the piece not usable. I was able to somehow boil the other two just good enough to use. They say the piece isn't hot but it is because there's near boiling hot water still on the device. So I got them to fit and was excited to use the whitening gel. I did 22% Carbamide Peroxide for 30 minutes and noticed a big difference in shades. But those 30 minutes were filled with uncomfortableness! Despite the trays' slimness, they are still just too thick and clunky. It is hard to wear these for any amount of time. I had a large amount of saliva generated during that time and was worried about swallowing it due to the possible leak of the peroxide. So what does one do with all that? You can either swallow it with the peroxide, try to spit it out without losing the peroxide, or you can wad a bunch of tissue into your mouth. That is what I did and it was OK. Ultimately, I was able to whiten my teeth(one time) but the process made me want to go to the dentist to get an actual custom tray. I will not be using these cheap-o trays again. For the money, I guess you could say its worth it. But I just don't think its a good idea to use these because they don't actually fit perfectly to your teeth. I did get a burnt gum from the peroxide and I wondered if it had to do with the trays being deformed. I would not buy this again and in fact am going to the dentist tomorrow to get custom trays. There are some things that it is worth it to get the real thing. For me, my teeth are precious and I want to be able to have a professionally done cleaning and whitening. I thought the cheap route would be good enough and would save the hassle but now I think it would have been better to just take the hit and go to the dentist. Good luck!

## Questions & Answers

**Q: are these bpa free?**
A: BPA is generally used in hard plastic, not soft. But it's plastic -- so it's made of chemicals. But probably not bpa.

**Q: Why are there 3?? Wouldn't you want an even number, one for upper and one for lower?**
A: It's 3 sets so 6 pieces total

**Q: are these mouth garards**
A: Yes, they are mouth guards but I used them as teeth whitening trays as they are sort of thin and flimsy.

**Q: How long for delivery? I've been waiting and waiting...**
A: I think it is shipped from China via tug boat.

### ⭐⭐⭐⭐⭐ Good price, easy to work with
*by K***N on January 20, 2025*

I use those to make myself a mouth guard for sleeping. I only use a bottom (mandibular) guard, so one is enough. I use a heat gun to mold it to my teeth's shape (using a pre-made mold of my teeth) and then cut it to only cover the teeth (you don't want it rubbing on your gums as it will eventually wear them out). It works great and last a long time.
