## Customer Reviews

### ⭐⭐⭐⭐⭐ Happy with this purchase
*by R***S on September 1, 2016*

These are very reasonably priced. If you've ever tried to fit one of these things to your teeth, you will appreciate the fact that these instructions are clear, and you have 4 shots at it. The mouth guards are thick enough to do the job, without being overly clunky once fitted. I do have a rather small mouth, so I trimmed them down with scissors. If you have the same issue, note that it is MUCH easier if you trim these BEFORE softening in hot water and fitting them. This way you won't have jagged scissor marks poking the inside of your mouth. I use these myself, and I also ordered a set for my mother in law when she mentioned her dentist wanted to charge her $85 for one fitted mouth guard. (These may not be a sufficient substitute for everyone when compared to a product from your dentist, but in her case, it was sufficient).If you found my review helpful, please click “yes” below to let me know!A quick breakdown of my rating system:5 STARS – the item is exactly what I expected and fulfills its purpose. I would definitely buy again, and have no desire to shop for an upgrade.4 STARS – the item might have a minor flaw which does not affect functionality. I would not actively shop for an upgrade, but would consider purchasing a different kind next time.3 STARS – does the job but is not impressive. I would only buy it again if I absolutely could not find a better option.2 STARS – doesn’t fulfill its purpose. I would not buy it again, but I might continue to use it while I shop around if I am desperate.1 STAR – doesn’t fulfill its purpose and is so bad that I actually refuse to (or can’t) use it at all for any length of time. I would actively avoid buying it again.

### ⭐⭐⭐⭐⭐ A satisfying purchase
*by M***. on February 11, 2016*

These work well. After reading the reviews and postings of others, I decided it was worth a try. It IS very important to read and re-read the instructions . . probably have them right by your side with a trusty Timer when you are first heating them up. This is a very heat sensitive material and they are not limiting the time in hot water for no reason. I'm sure this will be mush if left in longer than specified. Fit perfectly on first try although they say you can re-do. My purchase was for clenching overnight but I'm sure these would work nicely for teeth whitening as I have done that in custom-made trays. If you've never worn braces or had other fitted items in your mouth, it might feel a bit odd. But, nobody is telling you to go out in public with it! :-) The price is really terrific when compared with alternatives. So far, I'm still on my 1st tray and it looks like day one after about a month.

### ⭐⭐⭐⭐ 4 Nice cheap basic dental guard
*by J***A on December 18, 2015*

These are a great value. I don't think you can find four mouth guards for this cheap anywhere else. The quality is that of any other inexpensive dental guard you would use for sports. Imagine the free dental guard given to you when you played football freshman year. It's pretty basic. I don't think I would use this for nigh time grinding. It's pretty bulky, even after trimming it down. The fitting takes some practice to get the water just right temp and not melt it into a ball. I lost one this way but had a better outcome on the second. I've always had problems with these but maybe it's my lack of patience. As for a a teeth whitener tray, sure why not? It forms to your teeth which is all you need. I am keeping mine for basketball or other extra curricular activities but i don't see myself sleeping with it.Almost forgot, the instructions warn not to use this for severe teeth grinding like Bruxism or TMJ associated with sore teeth or jaw. Very odd because this was the only reason I purchased the product.
