DenTek Mouth Guard for Nighttime Teeth Grinding, Professional-Fit Dental Guard, 1 Count

I have been using this product for a decade or more, and it just gets better with each improvement. My first dental guard was custom-made by my dentist for a lot of money ($100s, as I recall), and it lasted maybe a year. I decided that was way too much to pay, so I got one of these for around $20. I can now use them for over a year before they wear out. They fit tight and don’t bother you at all when you sleep. The formed part does eventually detach from the the flexible plastic outer guard, but that process takes months to complete, and you can still use it till it completely separates. The key is to brush it thoroughly every time you brush your teeth, so it stays clean and sanitary. You can ignore the "don’t wear any longer than 6 months" advice, unless you have some peculiar dental problems. I don’t, other than bruxism (teeth grinding).One tip: before you heat the new mouth guard and insert it into your teeth, practice a couple of time to make sure you align it properly. I heat it on the stove in water rather than using the microwave, just because I trust that more.Second tip: when you’ve heated the mouth guard properly (follow all the instructions), and are ready to stick it in your mouth, don’t bite down too hard and also leave just a little bit of room in front of your front teeth for some of the silicone to remain there as you bear down with your bite. If you bite down too hard you will hit the flexible plastic outer guard, and that will weaken the bond of the silicone to the outer guard, shortening the life of you mouth guard considerably. Remember that most of the grinding and wear come from your back teeth, so you want a bit more "cushion" back there than in the front, so think of biting down with more pressure on your front teeth than on your back teeth. I know that sounds weird, but practice it a little, and you will see what I mean.Third tip: once you have bitten down on the new mouth guard, maintain your bite until the directions say to let loose, and very slowly remove the guard from your teeth. It will want to stick at first, and you don’t want to yank crowns off as you remove it. If necessary, swish a little water around in your mouth and then ease the guard off your teeth.If things don’t work the first time, you can try one more time, but the mouth guard will probably not last as long or fit quite as well, so get it right the first time! Practice!

For the price and my needs it works great. I learned recently that I clench my teeth when I sleep. I had a tiny fracture in one of my teeth that started this discussion and then started waking up with jaw pain and headaches. Instead of paying a few hundred I thought I’d try this out first. If it doesn’t work, no harm done.I followed the instructions pretty closely and was able to get a solid impression just using my phones selfie mode camera to see if the mold was positioned ok. I do have a small mouth but the guard itself is fairly small. It does not cover my back molars (wisdom teeth were removed) but it does the trick. I only use one guard for the top.I also sleep with a CPAP (nose) and find no issues with using a mouth guard and now no stress about clenching my teeth. I do not think I’m a heavy clencher and do not grind my teeth so I can’t speak to the toughness bc if my issue was more serious I’d put some serious money into it. So with my situation and size of mouth, this product worked great.

I’ve been grinding my teeth at night for years, and after waking up with jaw pain too often, I decided to try the DenTek Professional‑Fit Dental Guard. The boil-and-bite molding process was straightforward thanks to the clear 3-step instructions (heat, shape, wear) and a fitting tray that really helps get a snug fit.✅ What I Loved:* Comfort & protection – The soft top layer is comfy, and the strong bottom shields molars well. I wake up with significantly less soreness or tooth sensitivity.* Value – At around $16, it’s a solid alternative to a custom guard that costs hundreds. The 6‑month warranty and BPA-free EVA material are nice bonuses.⚠️ A Few Quibbles:* Tricky mold timing – My first mold was slightly off; I had to carefully follow the hot water timing and re-mold once.* Size & fit – It’s meant for upper teeth only, and people with smaller mouths might need to trim it beforehand.🏁 Bottom Line:If you grind moderately and want dentist-level fit without the price tag, this DenTek guard is worth it. It’s comfortable, cost-effective, and does the job—just be patient when molding and trim if needed.
