Mouth Guard for Grinding & Clenching Teeth BPA Free 4 Guards for Adults & Kids Dental Guards Bite Guards Night Guards for Teeth Grinding Teeth Grinding Mouth Guard for Sleep by M3 Naturals

Very easy to mold. I am an adult w a small mouth and I was able to use the bigger tray and cut it to size. This really has helped me with my tmj headaches. I also used the small one to customize for my 7 year old. Fits great.

I'm usually pretty good at reading directions, but these are challenging. There are 2 sets of instructions printed on outside of the box (as another reviewer mentioned, it's a very nice box), and they are similar, but different, which has probably led some people to a melted mess and tossing the whole thing out.It seems there have been different versions of the product. Here's what came in my box, (as printed on the box)1 - Large Mouth Tray (this one is clear)1 - Small Mount Tray (this one is clear)2 - Heavy Duty Mouth Guards (these are cloudy white)1 - Storage Case (blue)One side of box says to immerse the mouth guard (size of your choice) in water and leave for 18 seconds, no longer than 20 secondsThe other side of the box says immerse the heavy duty mouth guard and leave for 20 seconds, no longer than 25 seconds.Neither side says anything about mouth trays.I spent some time trying to figure out which was what, and what was supposed to be immersed in water and for how long, since nothing is labeled inside the box. I started with what I assumed to be the heavy duty mouth guard, and immersed it for 20 seconds, (it almost stuck to the side of the pan, which would have been the end of the guard) and fitted it gently, following the instructions, and it worked, but it was bulky and uncomfortable.Read every word on the box again, and then checked the company website, which is sorely lacking in information. Read the Amazon questions and reviews, lots more information, although not much of it helpful. Then armed with enough knowledge to be dangerous, started experimenting.I decided the "Mouth Tray" is actually the "mouth guard" mentioned on one side of the box. Tried immersing the large mouth tray for 18 seconds. That turned out to be a little long, 15 seconds probably would have been better. Popped it in my mouth and pressed gently, did the sucking thing they recommend, which helps the silicone form to your teeth, waited a bit, and presto, I had a comfortable mouth guard that doesn't cause me to gag.Some pointers...• Start with the Mouth Tray or clear guard, and follow the 18 second instructions.• Really let the water cool down for a minute or so after removing from the heat• Watch the guard as it soaks, if you see the edges start to bend, take it out of the water• Use a plastic spoon, and keep the guard from touching the sides or bottom of the pan,• Keep your plastic spoon under the guard the whole time it's soaking (all 18 seconds)• Really do the "close your mouth and use a sucking sensation"• My guess is you only wear a top OR bottom guard, not both. Instructions say the "top row of teeth"This all needs to be done fairly quickly, because as the guard cools to mouth temperature, it hardens and that's the shape you get.Once you've tried the mouth tray, follow the instructions for the Heavy Duty Mouth Guard, (the only difference is how long they soak) and see which one feels better.Once the guard is fitted, you can trim off any silicone that is uncomfortable, but don't cut so much away you ruin the structure of the guard.All in all, this seems to be a great product, (so far, I haven't actually slept with it in my mouth yet) and for the price, if you mess one up, it's not a disaster. But the instructions really need to be rewritten, and tested by someone who has never seen the product before.I'm happy they're made in America, the box is very nice, but I can see how people could easily meltdown (both the product and their temper) with having to figure out how to use them because the directions are misleading and incomplete.Hope this helps someone from tossing the whole thing.

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.

Packaging is confusing. You don't get four guards. You get two mouth guards and two trays (one large and one small). I know this will sound ignorant, but I do not know the difference between the guard and the tray. I've never used a mouth guard or a mouth tray. There are no labels on the items in the box. OK so the instructions for forming the product to your teeth are pretty straightforward but not so effective. Once I figured out which was the tray and which the guard (after boiling the wrong thing) I boiled, fit, reboiled and refit the item until I got it semi comfortable. Then I took a scissors to it and started cutting to get it to fit better. It kind of seems to fit now. Even though it's indicated the things can be molded to top or bottom teeth, it doesn't work so well on the bottom teeth. Overall, it's not that bad. I mean it doesn't hurt. But maybe there's something better.
