Q: How do I microwave it
submitted by Karen G - 1 month ago
A: Hi Karen, in order to mold the mouth guards to your teeth, bring a pot of water to a boil and remove from heat for one minute. Using a large metal spoon, fully immerse the heavy duty mouth guard into the water. Leave for 20 seconds (no longer than 25 seconds). Remove mouth guard from pot and lay on a paper towel. After 3 seconds pick up the mouth guard and place it on the top row of teeth. Once secure, gently press upward with your thumbs to form a mold around your teeth. Then close your mouth and use a sucking sensation to create a tight fit.

Q: I bought the M3 naturals mouth guards. Which is the one I boil to fit and mold to mouth upper teeth? The clear one? Instructions say "heavy duty one". Could you please explain. Thank you
submitted by Norma - 2 months ago
A: Hi Norma, thanks for your question! You can boil any of them to mold to your teeth. The set comes in two sizes (small and large), so you can choose whichever fits your mouth best. There are also two color options: clear and frosted.

Q: Can I used in tandem with clear retainers?
submitted by Melvin - 4 months ago
A: Curious minds unite, Melvin! We're glad you're exploring options with the Mouth Guards for Nighttime Teeth Grinding, Clenching & Sensitive Teeth from our premium collection. While these 4 custom-fit retainers with case are designed for standalone nighttime protection, using them alongside clear retainers isn't typically recommended unless approved by your dental professional to ensure optimal comfort and effectiveness.

Q: Am I to use only 1 mouth guard (either on top or on buttom) or best to use BOTH top and buttom mouth guard at the same time? If only to use 1, which is better to use, top or bottom? Thanks
submitted by Melanie - 5 months ago
A: Thanks for reaching out with your great question, Melanie! We’re thrilled you're exploring the benefits of the M3 Naturals Mouth Guards for Nighttime Teeth Grinding, Clenching & Sensitive Teeth, 4 Retainers with Case. Typically, most users only need to wear one mouth guard—either on the top or bottom row—rather than both at the same time. Which arch to wear it on can depend on comfort and dentist recommendation, but many people find the upper guard to be more natural to keep in place overnight. We recommend consulting with your dental professional to determine the best fit for your needs. We're glad you're prioritizing oral health with M3 Naturals!

Q: Is there an alternate way to heat this for the first moliding that doesn't need a microwave?
submitted by Sea - 7 months ago
A: Hi Sea! Thank you for your question! Yes! If you don’t have access to a microwave, you can heat the mouthguard using stovetop boiling water. 1. Boil water in a small pot on the stove. 2. Remove from heat and let it sit for about 30 seconds to slightly cool. 3. Submerge the mouthguard in the hot water for 30-60 seconds (check instructions for exact timing). 4. Carefully remove using tongs and let it cool slightly before molding to your teeth. Let us know if you need further assistance!

Clench it
I have a clenching problem while sleeping… I guess I need a dentist type made as it would be easier. Thanks

Hi Dillie! Thank you for sharing your experience! If you're finding the M3 Naturals Mouth Guards challenging to use, a custom-fit option from a dentist might provide a better fit and comfort for nighttime clenching. We appreciate your feedback!

Love these
I have used this as a night guard for the last few years. I enjoy it because it fits well after I trim the top part off just a bit. Easy to clean and last awhole
1 reply from M3 Naturals Customer Service team - 7 months ago
It’s great to hear that you’ve found a night guard that works well for you! 😴✨ It sounds like trimming it to your perfect fit has made it even more comfortable, and the fact that it’s easy to clean and lasts a long time is definitely a bonus! Glad it’s been helping you for the last few years. 😊

There are not 4 guards
There are 2 guards and 2 "trays". Both guards are too short to reach molars and are very very thick making them uncomfortable to wear. Box says remoldable but I don't trust it. Do not recommend.

Landfill Filler
These were misshapen right out of the box. Their “large” size is too small to reach the back molars. And it overly shrinks after cooling, making them painful to wear. For comparison, I routinely wear a basic sports mouth guard, so I know how a good guard should fit. This product is, sadly, landfill filler.

Bulky and awful
Bought these to temporarily replace a custom hard plastic night guard, but couldn’t stand them. They’re made of soft silicone, which apparently needs to be very thick to offer any level of protection… it feels bulky and terrible. I couldn’t tolerate having it in my mouth for more than a few seconds, let alone trying to fall asleep. This was after trimming it down as much as possible. Bad buy.

waste of money
I placed in the boiing water after I had turned off the heat following instructions and it was so flimsy, it fell apart. The second one I took out at 17 seconds and same thing happened. Could not wear, they fell apart. Waste of money.

Garbage
Should have listened to the bad reviews. Doesn’t mold well to your mouth and if you leave it in hot water for greater than 25 seconds, it completely melts.

Not for heavy grinders
It was comfortable and easy to wear, but I bit through it in a week. It’s not a good option for heavy grinders.

It was great for the price.
The price is great with these. They can get a bit soft very quickly, so be very careful with the size of the appliance. This is a great option for a fraction of the price.

The mouthguard is comfortable.
My dentist made a custom mouth guard for me to prevent damage from tooth clenching. The mouth guard wore out. I have been using these for about six months. I trimmed the first guard I made because it was too big for my mouth, and the cushiness of these is better than my old hard guard. Despite it being still usable, it is smaller than I wanted after heating it. The rest of the guards fit perfectly. The guards are thick when I first put them in my mouth, but I get used to them quickly.

Working well so far. It's a bit of an end user.
The packaging and listing are confusing and need to be addressed. Two sizes of mouth guards are included. Each adult and child size of the clear and frosted plastic versions is the same. There is no mention of what to use where or what purpose the second version appears for in the listing. Not a big deal, just hope they can update their packaging in the future, because everyone seems to sell the same product at a similar price. In the Q&A section, I read that this is made in the USA, but the packaging only says 'Distributed by' with a Florida address. At the very least, this would be supporting an American company, but I don't see any indication that the product is made in the USA. In a costsavings measure, the directions are only on the outside of the box, and the product is the only thing in it. An observation is not really a big deal. Since it says 'boiling water, then take off heat for 1 minute to establish water temperature', the directions on the back are probably better than most. After following the directions, everything worked great and exactly as it was supposed to. I had to trim a bit so that it wasn't just filling my mouth, because they come with enough excess to fit any mouth. I only purchased this to protect my front teeth, so it may depend on your specific use case. One suggestion I can make is to cut at an angle. The materials end up with squaredoff edges that are at least 116" in thickness, which is very large in the mouth. You don't feel it as much with slanted edges. I wish there was a better way to get rid of the excess thickness. I tried a utility knife and a hobby knife. It suited my needs and is working well. There is no weird taste or anything like that. It was easy to setup.

Teeth grinding relief
I’m a huge fan of these retainers. I grind my teeth very bad in my sleep and these have helped so much. They come in different sizes too so you can ensure they will fit.
