- Highest level of comfort - the Flex is soft throughout
- Strong enough to prevent damage from teeth grinding; easiest to wear
- Excellent first-time upgrade from “boil & bite” guards
As comfortable as night guards get, the Flex gently stretches over your teeth to provide a soft but protective barrier that prevents damage from teeth grinding. If you are a light grinder or only clench your teeth, the Flex guard can provide you with plenty of protection without sacrificing any comfort.
Even if you are a moderate or severe grinder, the Flex will comfortably prevent damage to your teeth and jaw - and the replacement cost is so low that maintaining protection is super affordable.

Fits great
This is my first BiteKnight order, but definitely not my first of these types of guards. It fit great right out of the bag. I hope that it lasts at least five months as they say; otherwise, the price is on the high side. I did actually hear about this from the dental office… not online. They were saying that more of their customers were buying it online from you than having them make it. I also appreciated the speed at which I received the guard.
Happy Customer
I'm very happy with my grind guard; it is very comfortable, and I will be very happy to have the extra during travel. Working with BiteKnight was seamless, very happy. Thank you!
Excellent comfort and fit
Compared to over-the-counter clear guards you use by boiling and biting down, this one is 1000 times better. I can hardly feel it, and I sleep perfectly well with it. The fit is perfect as well! I would recommend these to anyone, and you can't beat the price!!!
Top-notch customer service
This is my 2nd time with the do-it-yourself night guard. This one is superior to the first one I got from a different vendor. But the best thing is the customer service and attention. Ellen and Jim took great care of me so I am giving this company 5 stars. I recommend them to everyone!
Durable and great fit
Great customer service and easy to use website. The guard is thicker than I thought which will last me longer. My last guard from another company was destroyed after 3 months. First night's transition is normal but only lasted a few minutes. I took my old guard and guard from these guys and noticed the fit with these guys were a lot better.
First night guard success
Got my first Night Guard and from day one I loved it. Slept like a champ and it is staying in my mouth no problem. I am completely satisfied and have already ordered the next one but for my bottom teeth this time for alternating wear. Great Job done at your lab!
Customized fit is much better
If you have trouble sleeping with a store- bought guards this is for you. Best thing I did. A perfect fit and extremely comfortable. If you asked my wife the difference in me when I sleep now, she would tell you it was the best Christmas present I can ever give her!
Comfortable and effective
Finally, a mouth guard that fits over my teeth. It stays in my mouth throughout the whole night. My last one was so harsh on teeth and jaw, I would wake up multiple times throughout the night. My BiteKnight 3mm softguard has saved me. I couldn't be happier with the fit. I cannot believe I paid $400 to the dentist for my last guard, and it didn't even work as well.
Prompt customer service and good prices.
had a bit of a problem but when i called biteknight labs they took care of it immediately. I will be sending the retainers I was unhappy with today and fully expect to receive something that I will be happy with. they have convinced me that their store will be the only one I will use and the prices are reasonable. Thank you BiteKnight Labs
United StatesSuperior Service & Products
I have had all 3 night guards, the armour, sheild and flex. I have ground my teeth for over 40 years and I wish I would have had biteknight years and years ago. I would not have the damage I have today. The guards are as described, great quality, and the service is fast. Thank-you biteknight!
Excellent shopping experience!
I first heard about this company from my sister. This is my second order, I am extremely satisfied with my experience. The customer service was exceptional, and they went above and beyond to ensure my satisfaction. I will definitely be a returning customer for a long time and will recommend this company to others.
Personalized, responsive, and good value.
My husband and I both use this service and have had a great experience. It's far better than the stuff we've gotten on amazon! We like that it's personalized to our teeth, not just off the shelf product. And they are very responsive if you need help with anything. This is definitely a good value for money!
Great communication from customer service team
I’ve only been using my mouth guard for a short time, but so far I love it! The customer service team was very helpful and kept me updated as to the progress of my order.
Saved me money
I love this mouth guard. So much more affordable than going through my dentists (which would have been $500) . . . so glad I found these guys !! Thank you BiteKnight Labs !
Impressive product, unbeatable price!
My dentist told me that I needed to replace my guard because it was yellow and beginning to crack. The cost would be $600.00 out of pocket. Yikes. This company sent me a kit which I followed carefully and sent the impression back to them within 2 weeks of making it. I received the guard in just over a month. It fit perfectly, was comfortable, and stayed in place all night long. The price? $99!!!!
Comfortable and affordable
I have a few teeth that are very close together and crowded, so I was worried that this mouthguard would not fit well and actually interfere with my sleeping. However, it fits perfectly and is super comfortable! This is much more affordable than the one from my dentist and way more comfortable!
