Review: DO NOT USE A MICROWAVE OVEN TO FIT IT!!! - Pay attention to the reviews. If you have slightly misaligned teeth or jaw, DO NOT USE A MICROWAVE OVEN TO FIT IT! - like the instructions suggest. What happens is that the white tray that holds the guard during fitment is designed to work with perfectly aligned teeth. If your teeth or jaw are slightly misaligned, fitment will be difficult and potentially painful if you use a microwave oven. This is because the microwave oven will soften the blue material of the guard itself, but not the white tray. I recommend boiling water in a pot and submerging the entire thing in it. This will cause both guard and the hard plastic of the white tray to become flexible at the same time, and if you have misaligned teeth/jaw, this will do the trick. The tray will then accommodate itself to the irregularities of your mouth. Overall, this is a very good mouth guard. It has a "minimalist" profile that I find quite comfortable. By comparison, I also have the regular Dentek "Professional Fit." That one is easier to fit, but it is more uncomfortable to use because it has a lot of material. It feels like a sports guard, kind of bulky and intrusive. The material is hard too. The Ultimate Guard is not bulky at all. Because of the small profile, it could fall off. If you sleep facing up and tend to open your mouth in that position, that could be a problem! But if you sleep sideways (like most people), then no problem.
Review: ENDED UP LODGED IN MY ESOPHAGUS!!!!! - I bought this mouth guard last fall, because I was having tooth pain from grinding in my sleep. It worked great for a while as it’s small and comfortable but I did have issues with it staying in place. I woke up a few times when it had fallen out and I was chewing on it in my sleep, but I didn’t think much of it. Until the fateful night, I woke up at 3 am seconds after having swallowed the mouth guard. I felt it go down my throat and then felt it LODGE ITSELF IN MY ESOPHAGUS. This was incredibly painful. Every time I swallowed I could feel my saliva sit on top of the lodged mouth guard before painfully making its way past. I could literally feel exactly where it was sitting in my chest. I ended up having to go to the ER to having the foreign object removed from my esophagus. Luckily it didn’t do any damage to my esophagus and it was removed in a 4 minute procedure, but OH MY GOD DO NOT BUT THIS PRODUCT. It costed me a couple thousand dollars after insurance in hospital bills to remove. It is way too small and does not stay in place well enough. It is not worth it just buy a bigger bulkier one. Sure the bulkier ones aren’t as comfortable but let me tell you what’s uncomfortable. HAVING A PIECE OF PLASTIC LODGED IN YOUR ESOPHAGUS.

## Questions & Answers

**Q: I have a small mouth. Does this fit well with small mouthes? If its too big,can it be returned?**
A: It has a tray that you bend to the shape of your mouth. Follow instructions to a tee and you'll be fine. I however experienced soreness while trying to mitigate TMJ so I stopped using it and learned to sleep with my mouth relaxed. As far as a return policy im pretty sure there isn't one.

**Q: Does this work good? Is it comfortable for a smaller mouth?**
A: I have a smaller mouth and it works well.

**Q: Can you wear this with braces?**
A: Yes, it sits on top of the teeth and would not interfere with braces.

**Q: Will this make me drool?**
A: I've been using this for about 4 months and it does not make me drool

### ⭐⭐⭐⭐⭐ Non-bulky mouthgard that really works!
*by J***E on January 10, 2026*

This mouthguard was recommended to me by a friend after I complained about the expensive mouthguard I got from my dentist being way too large for my mouth. I absolutely could not sleep with it. It was super uncomfortable. I went without a mouth guard for years and caused thousands of dollars damage to my teeth from grinding on them. It took me a few nights to get used to this one, but once I did, I am so glad I tried! I wear this every night and have done so for a couple years and have had no further issues with my teeth. It’s way smaller and more comfortable than the one my dentist gave me. I brush it with my toothbrush and toothpaste occasionally just to keep it clean. Highly recommend this if you have a smaller mouth and need something that’s not bulky.
