The Hard Night Guard

The Hard Night Guard is our strongest and most durable night guard designed and suited for heavy grinders and clenchers. The rigid surface acts as a extremely effective protective barrier for grinding forces of your teeth and is made out of a hard elasticized copolyester material, approximately 2mm thick. Due to the rigid nature of the material, it will be a tighter fit and therefore slightly less comfortable than other types, but will provide the strongest protection and durability from grinding.

What's Included 

  • A complete impression kit with easy instructions and pre-paid return mailer
  • A perfectly fitting custom made night guard
  • Light blue custom case for your night guard
  • Fast and free all-inclusive 3-way shipping

          frequently asked questions

          Great question! This is really up to you, and mostly a matter of personal preference.

          Most people find the Upper night guard to be slightly more comfortable since it's less in the way of the tongue. For a better fit, we also recommend choosing the set of teeth that is straighter or has had less dental work done.

          You can generally expect your custom made night guard to land on your doorstep about a week or so after we receive your impression. 

          As it's hand made, we take about 2-3 business days to create your night guard and another 3-4 days for shipping. Shipping is free all 3 ways but if you'd like to speed things up, there are faster shipping options at checkout or you can take advantage of the Fast Track option, where we can turnaround your night guard within 24 hours. Please expect minor delays during peak holiday times.

          Great question, but tricky to answer. This really depends on how heavily you grind or clench your teeth and which night guard you choose.

          Depending on your level of grinding, your night guard can last anywhere from 4 months to as long as 4+ years. That's why it's important to choose the best version of the night guard to properly match your grinding or clenching. As an extra guarantee, if your night guard does wear out within 6 months, the replacement is on us!

            Mad I didn’t do it sooner!

            By far 1000% easier and almost as quick as the dentist and way cheaper (even after insurance @ the dentist). Easiest impression process and with the photo check..worry free. Love that they keep your impressions for 2 years so you can do a quick re-order. Top notch customer service.

            Great to work with

            I needed an affordable mouth guard after I broke the one I'd had for 5+ years from my dentist. I am a teacher and not in the position to pay $600+ for a mouth guard! I did some research online and found Chomper Labs and I'm really happy I chose them. They were responsive and helpful and the mouth guard I chose is doing great. I would order from them again.

            I was nervous about ordering but piece of cake, piece of pie! Customer service is super quick to answer (even during this panini), only suggestion buy one extra putty just in case! Mine hardened almost immediately I ordered the Hard Guard & it fit perfect, I didn’t have any additional adjustments so I cannot vouch for that process. I am an a very very heavy teeth grinder and even though its thin it has been holding up well (I have had for a year and a half)

            Didn't Think it Was Possible

            To my surprise this night guard beats my $350 guard which took many hours at my dentist's office to mold and fit. Service was quick and I was always informed as to how many days I would have to wait. It takes 6 weeks for my old night guard to be made from a mold they have already. Chomper was less than 3 weeks from online sign-up to completion! Thank you!

            Customer for life

            I've spent well over 1k purchasing night guards over the years directly from the dentist. I have a pretty severe grinding issue, so every time I lose or break one, I have to replace it quickly. My first guard from Chomper Labs was so lightweight and comfy I almost couldn't believe it. It also didn't break. The newer guard is post wisdom teeth removal and somehow even more comfy than the 1st one! And this is the hard material guard. After messing up my impression on the newest guard, I couldn't be more impressed with the interaction I had with the Chomper Labs team. Great product. Excellent service. Doesn't get better than that. You have a customer for life.

            I am a heavy grinder and this is the only night guard that I can sleep through out the night. The customer service is knowledgeable and helpful in assisting me to pick the right thickness. The turnaround time was fast and was updated every step on the way. The night guard is comfortable and sturdy which fits perfectly!

            Excellent!!!!! Highly Recommend

            I have had occlusal guards years. I am such a powerful grinder that I grind through them and need a new one at least every two years. My insurance only covers one in a life time. So, I have been paying my dentist for the additional guards. Trying to save money, I ordered a kit from Chomper Labs. The communication was excellent and the steps were simple to make the mold of my teeth. I have to say that the workmanship is equal if not BETTER from Chomper Labs. The plastic is smooth and the impression fit well. I am so happy I took the chance to do this on my own and not through my dentist. Thank you for saving me money!!!!

            Just Buy It

            I have TMJ and clench my teeth all of the time. I’ve bought every over the counter mouth guard available and bit through most of them. I’ve been to 6 specialists in the Houston area and they all promised to help...for $9k+ out of pocket. I received my Chomper guard over a week ago. At first it was really tight and made my teeth sore, but I decided to give it a full seven days before sending it back. Now it fits perfectly. My jaw doesn’t hurt anymore. Ever. My daily headaches are gone. If you’re struggling, get this night guard. It’s a game changer.

            After going through DOZENS of mouth guards - some of them $50 or more, and having them break in the middle of the night - sometimes only days after purchasing them, we are having very good luck with Chomper Labs. They are comfortable and sturdy. Thank you for a great product!!

            RDA approved

            I'm a RDA (registered dental assistant), and the fact that I'm buying my night guards from these guys should tell you a lot. I'm super impressed with the craft and quality of this night guard. It's actually BETTER than what we provide our patients. Stays on snug, the perfect thickness so it's comfy yet durable, and you can tell the material they use isn't the cheap made in china stuff some other online retailers sell. I'm a customer for life - highly recommend!!

            Great Guards considering I grind and clench pretty tightly absolutely love the hybrid for comfort and for durability.

            Couldn’t get the mold done correctly. I had to request a smaller tray and then the putty was way too much and it went everywhere when trying to make the mold. I thought it was 100% satisfaction and 100 day trial but they are charging me $25 from my refund.

            Amazing mouth guard!

            I've had a series of huge OTC mouth guards and a $500 mouth guard through my dentist, the latter of which was destroyed by a dog 6 months after purchase. I was thrilled to discover my Chomper mouth guard was just as wonderful as the dentist's version at a fraction of the cost. It's incredibly easy to use and virtually imperceptible in my mouth. I love it and wished I'd discovered it sooner!

            You guys sent me a mold kit

            I know you guys know I have a recent mold, that’s why you asked me in this email how I liked my new night guard. But whomever is responsible for checking these things, they messed up. I’d like my new night guard from my existing mold. It isn’t even a year old. I don’t want to make a new one.

            Beautiful job!

            Thank you for your constant communication during my revised night guard due to my new crowns. The care to detail at Chompers is second to none! I would recommend you to anyone in need of a night guard. Thank you for my good night’s sleep!

            Everything I hoped for

            Starting with the website that actually asked me to determine the type of guard I needed through the process to the end result. It was everything I needed.

            So far , so good!

            I wear them every night and notice that I don’t have any weird jaw pain when I wake up. So I believe it’s working! I hardly notice them in my mouth. Great product!
