- 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.

Soft night guard
Service and communication were excellent. I was unsure this would work as I know night guards to be very substantial. I have a history of over-clenching, which I grind at night. I chose to have the soft rubbery night guard thinking it was less expensive, but not sure it would last. So far so good.
Very comfortable
This night guard is so sleek and easy to wear, I forget that it's on sometimes! I always wake up feeling better, and I can: A) protect my teeth from clenching at night and B) not break the bank at the dentist. Definitely get one of these, it's 100% worth it.
5 stars
Love the night guard! Using it for 6 months gives me peace of mind. My stress is gone, and a new one is here. Or I just save it for a later time! The model was fantastic, and I will continue to visit! Will recommend
Slim and comfortable
The ordering process was super simple and inexpensive (I was pleasantly surprised!). When my night guards arrived, I was surprised at how slim it is. I wear it quite easily now. I'm a fan.
very comfortable
The Occlusal Guard has proven much better than any of Walmart's microwave and impression approach. I can often forget it's there while playing an instrument and talking with friends. I would 100% recommend this model to others.
Very comfortable
Just ordered my second BiteKnight occlusal guard and I love it! I realize that my husband hasn't heard me grinding in the middle of the night since I got the first one. It's slim and comfy. The first one I ordered lasted me a year. I am impressed! A+!
Perfect fit
As advertised, the night guard/retainer is a perfect fit! And so comfortable that I’ve started using it for other purposes (like long flights).
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.
