The Hard Night Guard - for heavy teeth grinding and clenching

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.

        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!

          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!!

          Night guard

          I absolutely love my new night guard. It fits perfectly and you can’t beat the price. The customer service is amazing. I will always purchase my night guards from Chomper labs.

          Pleasantly surprised

          I lost the night shield that I made with my dentist and then I lost it... so I didn’t want to pay $600 again. Now I see that I shouldn’t have paid in the first time! The night guard is pretty good, and the sending back the teeth impression was also super easy since they provided everything. I didn’t send a part of my identification, but they found as soon I sent the email asking for it! Great service and easy talking by e-mail.

          Love it!

          I had a mouth guard that I got from the dentist and had for 8 years. I was in need of a new one and was told it would cost $670. While searching for alternatives, I stumbled upon Chomper Labs. I was drawn to their branding, reviews, price and quality of the product. I’m so glad I made the decision to purchase! The kit was pretty easy to use and I was able to share a picture of my impression with their review team and heard back quickly that it’s good to go. Once I sent my impression in, I got my mouth guard quickly. I was so impressed with how perfectly it fit my teeth! It was uncomfortable for a few nights but after wearing it for a bit, it got more comfortable. I am so happy with my purchase!

          Excellent night guard

          This is the first night guard I’ve been able to keep in all night! It’s very comfortable and the molding kit easy to use highly recommended.

          Very pleased!

          Dentist recommended a $650 night guard for my grinding. I figured there had to be a better option so I gave Chomper a try. Everything was easy from start to finish; customer service was helpful and responsive. Couldn't be happier with my new night guard. Love it!

          Wearing Already

          I purchased the thick one because I know I grind heavily, after the first night I already had a wear pattern/scruffs on the back teeth. I don’t think it will last a month before needing replacement.

          Perfect night guard! Just like Demtist

          I have personally purchased a dentist night guard before that was upwards of $300. Since I had work done on my teeth I didn’t want to pay another outrageous amount for the same night guard. This night guard is the same exact type of material as the one I got from my dentist! Awesome product!

          New mouthguard

          Great mouthguard! It fits perfectly and the material is just as described. Customer service was also really nice and got back to me quickly about any questions I had. I would definitely recommend it as an alternative to getting a really expensive one from your dentist!.

          Finally Relief

          The process was so effortless and the instructions were so clear and easy to understand. After just a few nights of using my guard I can tell that it is helping and providing relief from all the negative symptoms I was getting from grinding my teeth! Thanks Chompers!

          My first mouth guard.

          This was the first time I had ordered a mouth guard from anywhere, and I can definitely say I will be ordering from Chomperlabs again when the time comes. The customer service was the best! Every question I had was answered promptly, and any issues I had were fixed!

          Great job!

          The process to get my daughters mouth guard was so easy, affordable and it’s really helping relieve headaches she was getting from grinding her teeth and clinching her jaw. Getting ready to order another for me!

          Good Guard, Great Price!

          I'm a night guard veteran and I've had a really good experience with this one. I chose the "hard" night guard. When it came in it was very very tight and just ran it under hot tap water and let it cool around teeth after letting it cool down a little first in the air. After that little adjustment it was perfect. I will certainly recommend chopper to any of my gator biter friends.
