Fits small jaws, too!
I have a small jaw. One reviewer said it didn’t work for their small jaw, so I was hesitant to buy it. I tried it anyway, because my dentist recommended it to me. I’m so glad I did! The first time I tried to mold it, it didn’t fit right. So I tried it again, and it fit perfectly. I’ve been using it for about a week and a half now. It sits comfortably in my mouth, and I have no problems falling asleep. I bought it to prevent clenching of my teeth. Mild TMJ on one side with low pain in mid ear. Since I started using this, I no longer have any pain in my ear. I would recommend this. I bought another one for my husband, because he grinds his teeth. Hopefully, it will work just as well for him.

Doesn't fit small/petite mouth
I am a very petite lady with small bone structure and small mouth/teeth/bite. My dentist recommended this brand so I purchased from Amazon at the sale price. 1) It was very hard to get this soft enough to squish on to my teeth/bite. I had to keep re-heating the bowl of water (mug is too hard to fit the item). 2) When it finally was near boiling water, I followed instructions (twice). Slid the guard into my mouth to create the teeth shaping. My front teeth weren't near the front plastic as they describe while my back teeth were in the goopy stuff and the hard plastic was pushing against my jaw muscles. I let it set and then pulled out. I thought the hard plastic would come away but it does not. The "tray" isn't really a tray like other brands. the rubber guard doesn't come out or off of the harder plastic section. So, when I put it back in to fit to the teeth, the back plastic was almost gagging me and the front teeth plastic was poking out of my lips. You know what they say about 1 size fits all... it's all bologna! A big man might find this a good guard to use, but for the smaller woman, you should look elsewhere. 1) there is no product refund guarantee. The guarantee on the box says that it will always fit...no offer for refund if it doesn't work. Only phone number to have someone help you try and try again. I can't get my $ back now... waste from my wallet. I've purchased another brand that hopefully will work for me and if not, they have a refund guarantee.

Great Product for Those Without an Overbite.
I found this product to be generally good. The quality was good, and I liked the fact that it wasn't super bulky when you had it in your mouth. The case that comes with it is nice, and feels sturdy and the included instructions are thorough and really help with the molding process. I didn't feel like the mold was too tedious and it wen't by pretty quickly and overall I would recommend this to someone who has a normal bite. That's where my personal experience deviated from some of the other reviewers. I don't think this guard is a good fit for someone with a very pronounced overbite. When I was molding the guard I knew I was going to run into trouble by how far back the hard plastic on the bottom of the front teeth pushed my bottom teeth back. This moves my whole jaw back and doesn't allow my teeth to rest just behind my top front teeth like they usually do. When my jaw is naturally closed without the guard, my bottom front teeth are totally hidden by the top teeth. My overbite is pretty severe and I would assume people with underbites would also have issues with this thing fitting perfectly. I had to put way more pressure than necessary to bite down as the instructions said to mold it and when it is in my mouth it feels like there is too much pressure on my front teeth because in the mold process I had to put extra force to bite down normally and move the hard plastic bottom. I have used this guard overnight for three nights now and I have woken up with the same jaw pressure I felt before I got the guard. I think my clenching overnight with the guard is forcing me to clench harder to compensate for the awkwardly placed guard behind my front teeth. I also wake up in the morning with slight soreness in my teeth and the feeling like they are being moved. I can't verify that, but when the guard is in, it is very very snug, to the point of being borderline unconformable. So the bottom line is, I would recommend this in a heartbeat for someone who has a normal bite and want a good quality guard that will hold up well against bruxism. At this price point, it's hard to deny the quality you receive. However, I would discourage anyone with a mild to severe overbite to purchase this product due to the lack of comfort it will give you. It's just not made for overbites.

Good starter trial
Like many here, my dentist recommended I try this before committing the money to a professional bite guard for sleeping. I am mixed on this thing: I have a small mouth but it does fit me (unlike some of the people here) but it also does change my jaw set. It's not really small so it forces my lower jaw to just forward just a bit in order to keep my lips together. Otherwise, I am sleeping with my mouth open all night. I don't love this. I also find that when I put it on each night, my teeth have relaxed just a little so it's uncomfortable. This is my first time trying a guard so I don't know if they're supposed to make you drool like crazy or not, and I find I work my jaw way more all night snugging it back into position. It never falls out or off but it does loosen a little and I have to bite it back up. So it's a pain and it's keeping me from really sleeping well. I'm sure, however, that it's working to protect my teeth so I'm torn on the whole thing. I did have to melt it twice to work the fit but it is a fine fit and compared to a pro guard, very much worth the cost. Not sure if I can commit to it 100% even after several weeks of on and off use. If you don't use it, what's the point, right?

These work and aren't uncomfortable. I clench my teeth at night and these Stop the sore teeth and teeth damage. Easy to fit and use. Comes with a carry case for travel or storage.

歯ぎしりに悩んでいるのでこちらを購入してみました。 海外のものなので若干不安があったのですが、 丁寧な日本語案内文が同封されていたので それにしたがって順番にやっていけばオーケーでした♪ 実はこの前にもっと安いのを購入したのですが、 作成の段階でなかなかお湯の温度を保てずに 商品がまるまってしまいました。 その点、こちらはお値段はするのですが 沸騰したお湯であれば大丈夫、とされており 確かに簡単に自分のマウスピースが作れました! 素材が2層構造になっていて丈夫で安心ながらも 前の部分が薄くて邪魔になり難いです。 どの程度持つのかが気になりますが、 とはいっても歯医者に行くよりはお安いので 様子見ながらリピートしようと思います♪

I received the guard today in the mail. It was easy to mold to my teeth. Took only a few mins. It's soft and comfortable on my teeth and almost suctions to my teeth the fit is that good. I'm a clencher and I know this is going to be great for me because when I have the guard on my teeth, it forces me to have my mouth open a little as is takes up room in my mouth and it feels strange to try and close my lips around it. This will stop my clenching as my mom will be slightly open when I sleep. Looking forward to tonight. Great product so far.

The product is easy to custom fit. The instructions on the package are quite clear. The only problem is the size is a bit large. But it stops bruxism and protects teeth, and I can use the product every night.

I ordered it for my daughter who grinds her teeth that was interfering with the alignment of her teeth. After purchasing this product she claims that her teeth are coming back in place.
