I am a horrible teeth grinder. The dentist said That I needed to purchase a $3000 mouth guard. I didn’t have that kind of money so I purchased this pack of two sets of guards. I opted for the thicker set Because the clenching and grinding has done a lot of damage to my teeth and I wanted the most protection. Although it said on the instructions that the thicker set didn’t needed to be fitted, I opted to size it using the method that was stated for the thinner set. It fits perfect and I have been using it for three nights now and I already feel a difference in my TMJ. I suggest anyone who has problems with grinding teeth to get this as soon as possible to avoid having the damage to their teeth and jaw joint that I have. I only wish I had purchased this sooner. The price is amazing and the product does what it says. Read more

My dentist have been telling me I need a mouthguard for years but I couldn't afford the ones professionally made there. I'm lucky I stumbled upon this because it is a quality product for the fraction of the price!Not sure why Amazon is asking customers here to review this product's whitening capabilities? There is nothing on the box or instructions that indicates it does that, but otherwise, it's absolutely great!Not only is it easy to mold, but also they provide two sets of moldable guards, one small and one large so that you choose whichever works best for you!They do include a note with the product offering the next one free, which tells me there is a limited life for this product, and it would need to be replaced at a certain interval, which likely depends on the person and how much they grind or wear down the guard, I guess!

I was concerned about my ability to tolerate a full-size mouthguard because I really need to wear one for my teeth-clenching. Because of this, I cut mine down and molded it to my bottom teeth instead of the top teeth. I am amazed at how comfortable this is and I had no problems at all leaving it in overnight. I didn’t even feel it. Fitting to my bottom teeth makes it possible to wear during the day without it being seen or interfering with my speech, and it solves the original issue. Read more

I followed the instructions and set an 18 second timer to sumberge the guard in boiling water. The result was a melted mess. I sumberges the second one for 3 seconds, and it worked better, but it's too big and makes me gag (I have a small mouth). Read more

Works amazing! I'm a seriously extreme teeth grinder and clencher!! I've had a NightGuard (my dog chewed my up) for years that my dentist had made for me and I was still breaking teeth. With the M3 I was able to form it lower onto my gums and was secure! Other guard in the past I will spit out in my sleep. With the M3 guard it stays in and takes the impact off my teeth! Love it!

Truth be told, I was hesitant to order this product due to all the complaints regarding the guards turning to mush. But if you read and reread the instructions before you start and use a little common sense, its very easy. I've included lots of pictures of the products for reference as well.First let me say, the package says there are 3 sizes. In my estimation, that is incorrect. Heres what you get. (1) small regular guard, (1) large regular guard, and (2) large heavy duty guards. Three of the 4 guards are all the same size and there is no heavy duty guard for smaller mouths (but after molding - that wasn't an issue.)I have a small mouth with a high arched roof and upon inserting the unmolded guards in my mouth, the small guard felt good. The heavy duty mold hurt and felt very clunky, gagging me slightly. I refrained from doing any cutting/adjustments to see how things felt after the molding process.On with the molding process... The regular and heavy duty guards state different amounts of time to be submerged to soften them, so be sure you are looking at the right instructions for your mold.It says to boil your water THEN remove from heat for 1 minute to stand. Here's the problem... we have different interpretations of what boiling is. I turned my heat off a bit after the tiny bubble on the side wall of the pot stage, just as small bubbles started to rise. I definitely was nowhere near a full, rolling boil. I set a 60 sec timer. Then submerged the regular, small guard first, starting an 18 sec timer. I watched closely and at 16 sec, the guard started to slightly curl, so I immediately removed it onto a flat paper towel. Waited a 3 sec count, put it in my mouth pushed with my thumbs on my teeth, sucked as suggested, and continued to suck with my tongue pressing the guard on my teeth and roof of my mouth. I reheated my water to the same boiling point as the first time and followed the same exact instructions for one of the heavy duty guards but let it boil for 19 seconds, removing it at that same slight curl point and molded the same as the first.Both guards fit great and feel extremely comfortable! No cutting was required at all. I have yet to try sleeping with either guard in, but I will return in a couple of weeks with an update IF I see signs of wear in either from night grinding. So far, I am very pleased with this purchase. Read more

I grind my teeth at night. I’m always looking for a good mouth guard. These are not the first mouth guards I’ve bought and had to mold. I really liked that they came with “regular” and heavy duty guards. I molded all 4 even though 1 was a little small. Unfortunately, in less than a week I “chewed” through the first heavy duty one. In about 2.5 weeks I had gone through all three.I’m very disappointed. I really thought they would work well. I thought about ordering another and trying again, but I think I’m going to just buy one at sporting goods store. Read more
