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 You'll Get 

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

        Frequently Asked Questions

        How do I choose between upper or lower?

        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.

        How long does it take to receive my night guard?

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

        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.

        How long will it last?

        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 six months to as long as 6+ 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!

          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!!

          Well worth it!

          Great guard

          I’m super happy with my night guard. Also recommend the weekly cleaning tabs. It’s still looking great after many months!

          I have a big mouth

          I have a large head, mouth, and bite. Even the largest mold could not capture all of my wisdom teeth (I have all of them). Otherwise, I am VERY happy with the night guard. It is strong, yet very thin, light, and flexible. Believe me, I usually chew through dentist made night guards.

          Thin, comfortable, hard plate prevents urge to grind

          My previous night guard was slightly pliable and I’d instinctively chew on it at night, which was the opposite of what I wanted. This night guard is made of a clear, thin, and what seems to be durable material. My teeth slide around on it and prevent the instinctive chewing I was doing befor. I have this a four star because this is supposed to be the most durable guard and my clenching isn’t terrible, however, I have noticed that there are scuff/scratches/bite marks already from my biting. I think it had a long life ahead still but that does make me a little nervous. Overall, great product, easy to make the mold and send in, and the comfort and outcome from the product are very good.

          Excellent product and amazingly kind helpful staff

          I'm super busy and overwhelmed with my first year of teaching. It took me months to get my guard back to Chomper to have them trim it a bit so it didn't hug my molars so tightly. They took such good care of me and my guard is now PERFECT!

          Love my guard!

          I wear my night guard every night. It definitely has kept me from grinding on my teeth further. I love that it’s not bulky and uncomfortable but it gets the job done!

          Night guard

          I got 2 night guards. The 1st fit so well I ordered a second to have on hand. The second isn’t as comfortable as the 1st but it works as a spare. I also use it to travel. Both fit better than my previous night guard and I got 2 for less than the price my dentist quoted for a night guard.

          Thank You, James!

          James was very polite and friendly and made the process of getting my nightguard redone so seamless! James responded to my multiple emails in a timely manner and was extremely helpful every step of the way. The new nightguard fits perfectly and I no longer have any pain when wearing it.
