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.

Great Guard
I've been using this brand for years. They last a long time. I chew right through some other brands in a couple of nights, but these last!

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.

has potential to work well...
I bought this night guard because I have been having some very bad pain in my jaw area. I have severe TMJ, and recently it has escalated into inflamation in my joints. The dentist was going to make me a night guard for $300 but said that a store bought one would do just as well until I can save the money to get surgery (since lovely insurance doesnt cover hardly any of it.) The instructions were pretty clear, although I didnt get a good tight fit the first time so I had to dunk it again in the hot water and start over. Once I got a good tight fit I started wearing it right away. Its of course not the most comfortable thing in the world but its not terrible. When I have it in, I tend to salivate more though and sometimes it feels like I am drowning. I did notice my jaw getting better when I used it, but the stupid thing fell out (or I yanked it out in the middle of the night)every night. I would go to sleep with it in, and when I woke up it was gone. So I stopped using it, after about a month and a half. My jaw has started to get worse so I may try and use it again soon. Overall I liked the product, and what it did for my jaw but the inconvenience of the way it felt and it coming out every night was too much for me. I will keep it so that when my jaw flare's again I can try it out for a little bit, but it wont be something I use all the time.

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?

It does fit a small mouth
I myself have a small mouth, contrary to what my parents told me growing up. I do usually remold this guard a few times but this is also the fourth one I have purchased so it isn't a ton of effort. The guard for me lasts around 8 months and I try to keep a spare on hand if I notice I'm wearing a hole in it. It really protects my teeth, my dentist was pleased and as long as I keep up on replacing it, no cracked molars. The guard stays snug in place overnight, well secured to my top teeth. I don't find it overly thick, and if I to feel any uncomfortable rubbing I can trim with scissors. It's easy to mold and insert/remove. It had a good price point to where I can replace it without breaking the bank. The time between replacements will depend soley on the severity of your grinding issues.

My husband says they work great !

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♪

Did not reach my back teeth

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.
