TheSleepGuard Mouth Guard for Clenching Teeth at Night [Pack of 4, Small & Large Sizes] – Custom Night Guards for Teeth Grinding – Nighttime Protection During Sleep for Men and Women

I am extremely satisfied with how soft the plastic is. It is very, very comfortable in my mouth. I don’t love having something in my mouth while I’m sleeping at ALL, but the comfort of the plastic definitely goes a long way toward helping me do it. My first night, I had it in for an hour or two and then I just had to take it out. I slept some and put it back in around 4am because I could tell I had been clenching/grinding. I slept with it in from 4am to 7am and then I had to take it out again. I think it will probably take me a little bit to get used to it and to be able to sleep through the whole night with it, but the way I see it, any amount of time I sleep in it is cutting down on damage to my teeth!! (I’m also thinking of it like a new piece of jewelry — for those of you like me who wear certain rings 24/7, when you get a new one, it can feel like such a foreign object, but within a week of wearing it all the time, you don’t notice it anymore. I am determined to get my brain to such a point of familiarity with this guard that it completely filters out the feedback that it’s in my mouth! 😆) It’s probably worth noting that I’m on the spectrum so not everyone will be as overwhelmed by the sensory experience as I am. I have had trouble sleeping in earplugs, too. I have zero experience with dentist-made sleep guards so I can’t compare this one to those; however, I will say it is noticeable in your mouth and while I wouldn’t call it bulky, it’s also not discreet or subtle or “a perfect fit.” But it definitely works and it is definitely an excellent value for the money. The instructions were on point and easy to follow; the comments on the video were also helpful. One guy said that the top teeth are usually easier to fit than the bottom teeth but you can fit whichever one you want. You do not wear a top guard and a bottom guard at the same time. Possibly this is obvious to most people; it was not obvious to me and it was only thanks to someone else’s review that I learned it. I fitted to my top teeth. I’m tempted to boil water and go through the fitting process again because I have a hunch it could be fitted just a bit more snug. But even if I don’t go through the process again, I am happy with it. You get two small and two large. I like that a lot because it gives you a spare if you mess up. And if you don’t mess up, you can make a guard for top teeth AND bottom teeth if you want to change it up. ;) It definitely stays in place. No issue there. It was easy enough to mold; the only thing I would say about the process is use more pressure to mold it than you think is necessary because I think I didn’t use enough. It’s also possible my water cooled off too much — our home is drafty and chilly in the wintertime, so I suspect I shouldn’t have let the water cool quite as long as the instructions said. Overall, this product is 1) saving my teeth and 2) saving my money so I am giving it five stars. I have to get used to having it in my mouth and maybe it would be less of process with a dental-grade guard but I don’t have the money to spend on such a luxury. Time and patience will be my friends instead of money. 😜 One last remark: the case does not have any holes in it for releasing moisture? I’m not sure if I’m missing something, but this really bothered me. This is an item you put in your mouth, so I really need it to not be getting musty and/or moldy or mildewy. I couldn’t stand the thought of it sitting in an open case and I also couldn’t stand the thought of it building up condensation in a closed case, so I used a 1/8” drill bit to drill three holes in the top and four in the back (none on the bottom for obvious reasons) so that air can circulate the case without letting in any particulate (hopefully…). I wish they made the cases with a mesh-like pattern built into the plastic to allow moisture to evaporate. But this product is STILL protecting my teeth and saving me hundreds of dollars so it still gets five stars even though the case seemed less protective and more like a mini sauna for the mouth guard. 😬 I definitely recommend this product. Easy to use all around, and a very, very comfortable plastic. (Oh, last note — it protects teeth from damage but it does not help tremendously with the pain in a jaw from clenching. I am still researching what to do about that. I don’t normally have a problem with this to begin with, but life has been particularly stressful and overwhelming for the last month and I am pretty sure that’s why this problem has developed. If you’re looking for something to alleviate jaw pain, this isn’t going to help much, but it WILL protect your teeth so I would highly encourage using it anyway.) (No wait, THIS is the last note — it’s possible the case has no holes for air circulation because bacteria getting in is a bigger concern. I’m not sure. I modified the case because of how I understand the physics of it but maybe talk to someone smarter than me before you put holes in the case. I’m off to go research more about that myself…)

I’ve been using these mouth guards for about a week, and they really help with my teeth clenching at night. My jaw feels more relaxed in the morning, and I’ve noticed less tension and pain. I like that the pack comes with four guards and two different sizes — it’s convenient and a good value. They’re comfortable once you get used to them, and easy to clean. The only thing is, they’re not custom-fitted, so it might take a couple of nights to find the perfect fit. But overall, they work great and do exactly what they promise!

I like the idea of creating my own guard however my mouth is too small even with the smaller size. The video and directions are accurate plus easy to follow. I wished it had worked for me. MNH

Great product but was difficult to adjust

Ny wife has used multiple mouth guards in the past. After a new puppy got her last one, she ordered these as a replacement. She followed the instructions, and if anything, allowed extra time for the boiling water to cool, and when pouring the hot water over the product, within 5 seconds, they just started to warp/melt. She didn’t leave it in there the instructed 10’ish seconds. I understand that the water was too hot. That’s the only way this could have happened. That said, she waited 3+ minutes for the boiling water to “cool”, which is WAY longer than the instructions said to do so. Absolutely do not buy this, and if you do, know that the instructions are WAY off.

I’ve been struggling with night clenching for a while, and this product has honestly helped so much. The kit comes with 4 guards in 2 different sizes, so it was easy to find the right fit. The material feels durable but still comfortable, and molding it to my bite was simple. After a few nights, I noticed less jaw tension in the morning and no more headaches from clenching. The design is secure and stays in place all night. I also really like that it includes a case to keep everything clean. Overall, great value and really effective — definitely recommend if you grind or clench your teeth at night.

I bought these mouth guards because I tend to clench my teeth at night, and they work really well. The material is durable but still comfortable — I can sleep with it easily. It’s simple to mold and fits perfectly without any pressure. I like that the set includes different sizes and handy cases for storage. After just a few nights, I noticed my jaw doesn’t feel sore in the morning anymore. Great quality for the price — highly recommend!

I’ve been looking for a comfortable night guard for a long time, and this one turned out to be exactly what I needed. The set includes four guards in two different sizes, so it’s easy to find the perfect fit. The fitting process is simple just a couple of minutes in hot water, and it molds perfectly to your teeth. The material is soft yet durable, doesn’t cause any discomfort, and doesn’t interfere with sleep. I wake up without any jaw tension the result was noticeable after just a few nights. Plus, a nice bonus the set comes with neat storage cases. I’m very happy with this purchase!

I was skeptical at first, but The Sleep Guard has completely changed my nights. For years, I struggled with disrupted sleep due to grinding my teeth/snoring/restlessness (insert your reason here), and nothing seemed to help long-term. After reading a few positive reviews, I decided to give this a try—and I’m so glad I did. From the very first night, I noticed a difference. It’s surprisingly comfortable, easy to use, and stays in place throughout the night. I wake up feeling more rested, with none of the jaw soreness I used to experience. The quality is also impressive—it doesn’t feel cheap or flimsy like some other products I’ve tried. What I really appreciate is how low-maintenance it is. Just a quick rinse in the morning and it’s ready to go again. After a few weeks of consistent use, I’ve even noticed an improvement in my mood and energy levels during the day. Highly recommend this if you’re struggling with sleep issues and want a simple, effective solution. It’s been a total game-changer for me.

Love it! Easy to fit, super comfortable, and really helps with teeth clenching. Slept better from the first night. Great quality and worth it!

very good. Better than paying $500

I’ve struggled with jaw clenching and teeth grinding for years — I’d wake up every morning with sore teeth, tension headaches, and a stiff jaw. I’ve tried multiple mouth guards, but they only protected my teeth, not the actual problem. The SleepGuard has been a total game changer! From the very first week, I noticed a difference. It gently trains you to stop clenching without waking you up, and over time my morning pain has almost completely disappeared. I love that it actually helps retrain your muscles instead of just acting as a barrier. After about two weeks, I could feel my jaw staying relaxed even during stressful days. It’s comfortable to wear, easy to use, and you can see your nightly progress — which keeps you motivated. The soft tones are gentle enough that they don’t disturb my sleep or my partner’s, and I wake up feeling refreshed for once. If you’ve tried every night guard out there and still wake up with tension or headaches, give this a try. It’s honestly one of the best investments I’ve made for my health and sleep. Totally worth it!

Works well as long as instructions are followed carefully, i.e. 1) Don't use any plastic spoons or cups when you are moulding the night guard. The plastic will stick together. Only use a glass and a metal spoon. 2) You only need to mould one guard, to wear on your top teeth (I somehow thought I needed top and bottom until I realised my mistake) 3) You can re-mould if you make a mistake. 4) You can cut the plastic if it's too big, even after you have moulded. Even the small size was far too big for me. Ideally you should still be able to close your mouth when you sleep - if your mouth is open then your mouth is more susceptible to bacteria. I have been wearing my mouth guard for a month now. I am not sure if it will last too long, maybe a few months, but since there are a few in the packet, it's quite good value.
