- 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.

United StatesGreat customer service!
Great experience. I was able to quickly reach someone and they were knowledgeable and helpful.
Love it!
I absolutely LOVE my night guard! My old night guard cost me over $400, but my chihuahua puppy destroyed it with little bite marks while I was working (OUCH!). It’s great to get this high quality guard for so much less
Great fit
This is my second order and I am very happy with both. They fit well and they are a lot more affordable than a dentist for the same thing. I received it within days of ordering.
Great on budget
I'm super pleased with this mouth guard! It's a lot softer and lighter than the guard I got from the dentist at a much steeper price. Even though it's more comfortable than my old guard, BiteKnight's doesn't slide off at night. This was my first experience casting my own teeth for any impressions, and it was a fairly easy process. If you grind your teeth at night and you're looking for a quality guard at a budget price—this is it!
Great customer service experience
This is my third retainer, and this is the first time I had to speak with customer support. Both customer service reps were very responsive, persistent, and patient, totally committed to helping me resolve my issue. Consequently, I am 100% satisfied. Thanks!
Good customer service follow up
Great follow-up service. I initially experienced a problem with my new bite guard. I called, explained the situation, and BiteKnight was able to process a new one for me right away.
Comfortable dental product
It feels a little weird at first having it in when you sleep and in the morning. But when I take it out, my teeth feel much better and relaxed compared to not having it. Alignment and everything about it was great. Returning molds and getting what I wanted has been very well done. Great product and overall experience.
Perfect fit
I am absolutely thrilled with the fit. I didn't know I needed a new night guard. It is the best deep sleep I have had in a long time. I wish I wouldn't have waited so long. When you get used to it... I forget I have it in.
United StatesGreat fit!
My bite guards were a perfect fit and work great. The ordering experience and customer service have been great so far.
United StatesGreat product & outstanding service!
I was so pleased with the comfort, fit & durability of my Biteknight Flex Guard that when it came time to replace it (2 years later) I once again purchased from Biteknight. Note that even though I’d worn it almost every night, it was not worn through….just looked a bit faded. Thanks BiteKnight!
Great buy!
So far the device has worked great. It was somewhat difficult to do the mold yourself, but following the directions carefully, they eventually came out perfect. You have to push VERY hard on the tray against your teeth to make it deep enough. As of now, I would definitely recommend it to anyone. I am on the subscription program for every 4 or 5 months.
United StatesGreat product
My experience was amazing- customer service goes above and beyond to help
United StatesComfort over durability
Up front, I love these guards because they fit better and are for more comfortable than even the ones I've had from the dentist. However, since I didn't go for the thinnest/lightest option I'd hoped for moderate durability. Previous guards have lasted me a year or more, but with this one I already have some small holes forming from chewing through it and will unfortunately have to replace it much sooner.
Affordable but still great
I had tried one I bought on amazon and then found BiteKnight due to the buy one get one deal. I'm glad I did. It was a little more money in terms of average price per guard, but well worth it. Customer service is excellent, the quality of the guard is far superior. All of the instructions, including the way you ship your mold in, are easy and clear directions, and the finished product is excellent. I highly recommend these folks!!
Comfortable and easy to fit
This is the third mouthguard that I've acquired since I started clenching and grinding in my 20s, and so far it is by far my favorite! It was easy to fit, and the texture is far more comfortable and soothing than the hard sports type guard I'd been wearing before. It had cool colors but was very bulky and not the right choice. This one is highly recommended!
Easy
This product is excellent, and the subscription is very nice! The quality of this night guard is at least as good as guards you can get through your dentist. Additionally, the subscription plan means that you are getting the best price on all future orders.
