  • Great quality and easy to use
    This is great lightweight mouth guard that was very easy to fit and mold to the mouth. It is comfortable and gives a snug fit without giving any pain or discomfort on the gums. It is nice and hard once it hardens after molding and seems like it will hold up well. It is very easy to remold if you don’t get it quite right the first time. Just follow the tutorial and molding is pain free and easy to do. This is great for kiddos who are in the teeth losing stages and need to change up mouthguards often
  • Slim Fit, Solid Protection
    I’ll admit, this guard isn’t as comfortable as the gel or silicone alternatives, but it does its job well. It just takes a little time to get used to that firmer plastic feel inside your mouth. After a few months of basketball wear, you can clearly see where my grinding happens and how the material has worn slightly—but it’s held up better than expected, especially across the front where I tend to catch the occasional elbow.

    Overall, it’s a solid pick if you want something slim, simple, and low-profile that still provides decent protection. And it comes in every color imaginable—for anyone who likes, or whose 3-ball game depends on, a clean pop of Neon Flash or Athletic Orange!

  • Best Guard for the price!
    Best mouth guard I’ve had for such a cheap price! Breathable while you sleep and very comfortable!
  • Good for BJJ
    Easy to mold. Took a few tries to get the perfect fit. Easy to talk with. Using it for BJJ.
  • Great mouthguard for lacrosse!
    Amazing mouthguard! I use it for lacrosse and it provides protection while still being lightweight and very comfortable (especially compared to other mouthguards I’ve tried). Highly recommend!
  • Great for braces!
    Perfect for braces! I originally ordered the Shock Doctor because it doesn't need to be molded, but it still holds a firm shape that doesn't fit my mouth with the turbos and hardware I have. I brought this one to my adjustment and they applied a thick tube of wax across the brackets on the teeth that are being actively moved, anchoring it mainly to the roof of my mouth and molars. The process was really fast as well, so my office doesn't have a problem remolding it every adjustment to ensure it doesn't hinder treatment. The fit is perfect on the bite even though it's slightly bulky in the front from the extra space. I love that I can still drink water with it in so I can use it during the day if I start clenching my jaw. My only complaint is that it's not very long. I have a pretty small mouth, I'm a short woman, and I have all of my 4s removed but its not long enough to cover the back 1 and 1/2 molars. This works fine for now but might not be ideal for people with all teeth touching who grind their back molars.
  • nope, like x-mas wrapping an awkward shaped present
    As a person formerly in the dental field, this product is certainly not worth 20 bucks at all. The shaping is cumbersome so I had to use my former life's skills to "round" out the curves that stick out to make it more comfy. After 4 tries, I got it to an acceptable form which is still a little loose but overall the arch shape is there. If you had a mold of the arch - then at least you have an easier time to reheat and cool but while on the model - winging it in the mouth is frustrating. Use boiled water in a bowl and about 30 secs is just about the perfect balance between softening and handling. Best you can do is first mold the basic shape. Once set, keep the child biting down and look at how much you have to work to round out at the curve and then curl the back up to cover 1/3 of the cheek-side crown of the teeth. That's what will be the 2nd, 3rd and likely 4th to add finishing touches. Trying to isolate and dip the sections you want to "perfect". Maybe it's me trying to get office quality mold but if you're not good with this stuff, then look for a pre arched one and not this flat one. I only got this because it was "recommended" by the coach but from my view - not good. Best option but most expensive is the dentist, but replacing broken teeth is much much more so weigh the options. I gave it a shot, this is my review for what it's worth....
  • Good fit
