Buy this night guard!!!
This is perfect lightweight night guard. I had a more expensive one like this but my dog chewed it up so I decided to try this one! It is the exact same quality for way cheaper, because it is more lightweight and not custom, it does have more of chance of falling out so if you’re prone to that, try a custom guard from them. The fit is amazing and adjustable for all mouths. My jaw hurts significantly less when using it and it doesn’t affect the quality of my sleep. It’s so easy to use by just popping it in your mouth and being worry free. If I ever need another mouthguard I will be buying from this brand, when I received it I had peace of mind knowing if I didn’t like it I could just switch it out for one of their other ones but this one is perfect. They deserve more stars but 5 is all I can give.

DO NOT WASTE YOUR TIME OR MONEY -
I would give these <1 star if that option was available. 1. These are so flimsy that the adjustable strap is useless. It is impossible to slide the strap in and out to make any adjustments for a better fit. 2. Once I placed the pads on my bottom teeth and closed my mouth, they started spinning around. I placed them on my bottom teeth, closed my mouth and they spun around to my top teeth. Then they went vertical into my inner cheeks instead of staying horizontal. Once that happened there was no protection over my teeth at all. They might look nice online and be reasonably priced, but as the saying goes “you get what you pay for”. Do yourself a favor and pay a little more for the Dentex brand. I have been using them successfully for several years and will not be foolish enough to switch again.

favorite one I have tried for TMJ
I have TMJ and I clench at night. After trying several night guards, I finally settled on this one. It is the most comfortable and helps me to not clench my teeth. Also, spit does not collect in this brace.

very flimsy
So the actual part that rests on your teeth is more comfortable as it is softer. HOWVER..... the thin connecting piece which is supposed to be adjustable is very flimsy to the point that if you pull it out to adjust for longer, you will not get it back in at all. It flexes too much. So..... if you're going to take a chance on this mouth guard, I would suggest pulling them out a little at a time until you get the exact position you want becasue there's no going back to shortening it. Also, for anyone missing back teeth, it can not settle in place very well. I ended up biting my cheek so I went back to my more rigid other brand with no hitch. Bottom line is, that yes, it's more comfortable when you put it in, but once in if you don't have all your teeth, it tends to shift around. THe other con is the adjuster is way too soft. When I first received it and opened the package, it was all the way short. I needed to lengthen it and pulled it out too far and now cannot get it back in. So now it's useless for me unless I can figure out a way to do it. Maybe put it in the freezer to stiffen it up some. I'll try that, so buyer beware :)

Love these but don't adjust after first adjustment.
After wearing it for a bit, I have absolutely love the material for the bite piece. It's super sturdy, and there's only a small indent. Normally I chew through in a month, especially with how stressed I am. My ONLY complaint is the strap that adjusts. It's really flimsy. I'm missing my back molars on the bottom right. I need it shortened. Ift it lengthens you can t get it to go back in. That's why I loved the dentex ones but I would grind through them in less than a month. The strap just is kinda extra piece in my mouth like a string. These are way worth the price. I will buy again but I hope you fix the adjustable part.

Choking Hazard!
Total junk, will not stay in your mouth. Connector too flimsy and will not stay in position. Company does not except returns so look somewhere else. I would be afraid to sleep with this in my mouth, choking hazard!!

Wrong mouth guard for me, but amazing service
This mouth guard did not work for me since I have a very narrow jaw and even on the shortest setting, it was loose. But I am giving five stars for service since the seller responded the same day, gave me an immediate refund AND is helping me figure out which kind of mouth guard would work best for me, since they sell several. Especially in this day and age, customer service like this is a gem.

I get the concept, but not a good fit for me because I clenched my jaw
I had high hopes on this, as I wake up in the middle of the night, often clenching my jaw extremely hard, and I cannot sleep with my mouth open, so a traditional mouthguard doesn’t work because it leads a slight crack in my lips, which I just can’t deal with. Unfortunately, because of the way this one sets even when adjusted, I felt like I had to hold it in place which made me clench my jaw consistently instead of just on and off throughout the night, causing excruciating pain. Unfortunately, there’s no return policy so if you buy them, you’re stuck with the money spent.

This one works and is comfortable! I was able to adjust to it on the first night of using it. Easy to adjust for a custom fit.

Do not buy this product, it's useless. It isn't rigid at all, you need to bite down to keep it in place, and ultimately, that is worse for your jaw than not wearing it at all. This is a completely useless, and over priced product, that can't be returned because it's been in your mouth once you try it.

El producto está bien pero en realidad no se ajusta bien y es difícil de utilizar, además no permanece en su sitio. Quizás depende de la boca de cada quien.

Different type of dental guard. The rubber plates are stiffer and take a couple of nights of getting used but works for me, I really like that the plates are smaller and I sleep better than with a full-on mouth guard. I must commend the KOHEEL customer service. One of the 2 dental guards had a defect, I contacted them directly (rather than the seller on Amazon), they swiftly sent me another pack of 2, and another product free of charge to try out. Best customer service I have ever received.

Not a good device for wearing at night. Could end up swallowing it in your sleep. According to the pictures I thought that the piece of plastic between where the molars bite would be more sturdy. It is not! Terrible!
