Sentinel Hard Dental Night Guard

.40 (1mm thickness) ultra thin, hard dental night guard can be worn comfortably night after night or as a daytime guard. This hard stint secures your teeth in place and provides long lasting durability for light to moderate nighttime grinders.

.80 (2mm thickness) An added layer of thickness for extra durability. Ideal for nighttime grinding or jaw clenching. Suggested for moderate to heavy grinders.

A tip when deciding which night guard is right for you:

Keep in mind that your teeth may naturally shift over time. The Sentinel Hard Dental Night Guard fits snug & perfectly snaps to your teeth. It is an exact fit and leaves plenty of room for jaw movement. If your desire is to wear your night guard consistently (every night or at least several times a week) the hard acrylic night guard will be an excellent choice. If you know you will not wear your night guard on a regular basis, the Sentinel Dual Laminated Night Guard or the Sentinel Soft Dental Night Guard may be a better choice as they are both more adaptable and offer that little bit of “wiggle room”.

  1. Josh Turner (verified owner)

    Communication is fantastic! The dental impression kit instructions are informative and detailed enough that I can actually tell what’s going on. I took a great impression the first time around. Thanks Guys- GREAT SERVICE

  2. Briana Snellgrove (verified owner)

    When my dentist said he’d give me a deal on my second night guard I was stil heartbroken at the price. So thankful for the internet. Also, pro tip: I use castile soap to clean my mouthguard. Dr. Bronners on Amazon sells a big bottle of it. Better than the harsh toothpastes and denture cleaning solutions! Mouthguard fits perfectly . A+++

  3. Chris berry

    Worth every penny! I do all my shopping online already as it is so why not a night guard. Thank you for the great nightguard

  4. C. Redding

    After getting a guard through sentinel I now have a slight disdain for my dentist. He tried to charge me $520.00 for the same guard I just got for 135 through sentinel… what a joke. Awesome Price, Awesome Guard!

  5. Bailey Hamel (verified owner)

    Got my new guard in the mail today! Flawless fit! I’m actually looking forward to sleeping with it in tonight! Thanks Sentinel Team! A++++

  6. Danny Warner

    Wasn’t to sure about doing this online but the cost difference between my dentist and going online was worth it to find out for me. This worked great! I’m very impressed with Sentinel, they were quick and affordable. Thanks!

  7. Devon Hayes (verified owner)

    Excellent service! It has helped my jaw pain out tremendously. Much appreciated -Devon

  8. Gregory Mullen (verified owner)

    Same as dentist. Thank you sentinel team!!

  9. Jose Torres (verified owner)

    My dentist always made a big deal of adjusting my night guard so I was really worried about this one needing adjustments but I did not need anything at all. It feel great & snaps into place. Makes me think my dentist was doing a bit of “rousing the stone”. Happy customer!

  10. Darren Brock (verified owner)

    This team really does go to great lengths to meet customer satisfaction. I messed up my first dental impression and was quickly shipped another for free. Then wanted to change types after I received my soft night guard. They upgraded me and I just had to pay the difference in price. Way more flexible than my money hungry dentist! Great customer service.

  11. Selina M

    My husband and I bought 4 guards from sentinel just so we would have a backup since we like to travel. So I should be able to write 4 different reviews right??
    All of our night guards fit great. We are very happy with our whole experience with the company and recommended them to all of our friends. If you’re sitting there reading these reviews not sure to make the buy, rest assured this company is the real deal. We are real people who are now customers for life!

  12. Jose T. (verified owner)

    Can’t imagine why I will ever return to a dentist for a dental night guard. You guys are a serious money saver. Thanks bunches :))

  13. Lyza R. (verified owner)

    Very satisfied customer. I was blown away by the exceptional customer service and quality product. Would recommend to anyone.

  14. Connie Dawson (verified owner)

    Prompt shipping, fast turn around time and high quality product. Can’t beat it!

  15. Dan M. Salt Lake City, Utah (verified owner)

    Had a little trouble taking my dental impression. Had to go through three tries but third times a charm and I got it!
    The night guard fits great. So far so good. Thanks!

  16. Ronnie C

    Customer service is outstanding. I had a lot of questions and Alexandra was extremely knowledgeable, professional and kind. I got my night guard within two weeks of sending the impression off. Fit is excellent. I chose the 2mm because I wanted strength but wanted to keep it thin in my mouth since I’m a light sleeper. This company is very professional. Couldn’t be more thrilled to have found you guys. Thank you!

  17. Diana Matherne (verified owner)

    I did not think the quality was going to be the same as my dentist makes but it is just as good if not better and they offer a two year warranty. Can’t beat it!

  18. Austin J Carle

    Thank you so much for the guard! I feel a lot better knowing I saved money and I’m taking care of my teeth.

  19. Heather C. (verified owner)

    I’ve been paying $600 for a night guard (and replacements) for years through my dentist. I feel like I just got a steal! THANK YOU

  20. Randy Washington (verified owner)

    Just wanted to leave a quick review to let you all know how impressed I am with your customer service and high quality night guard. I have been through many of these (unfortunately paid way too much through my dentist) and I am just over the moon impressed. I highly recommend Sentinel Mouthguards Co. to anyone and everyone. Kudos!

  21. Kenneth H. (verified owner)

    I have pretty extensive damage from grinding my teeth for years. I’ve cracked three crowns and broken a veneer from teeth grinding. Needless to say, I should have been wearing a night guard a long time ago. Fast forward thousands of dollars later, I found Sentinel through an article online and decided to go for it. No complaints. The guard serves its purpose well. Thanks Sentinel:)

  22. Keri O. (verified owner)

    Will order again!! Thank You!! My experience has been wonderful. So glad i found you guys!

  23. Dustin Loveless (verified owner)

    One word- PERFECT! I had three different guards made by my dentist before I took a chance & ordered through Sentinel. The three guards from my dentist were all uncomfortable & bulky. A complete waste. I was so discouraged. I chose the 2mm night guard and it is perfect. My headaches and facial pain are gone. I’m very happy! All around great experience!

  24. Tom Wyrosdick (verified owner)

    Received my night guard about a month ago and have been using it nightly. I went with the .80 hard acrylic dental guard because it’s sturdy and I need to wear it every single night. It took me about a week to get used to it. It’s thin and it fit well but having something in my mouth at night just took some time to get used to. I saved a ton and I feel really good about my purchase. Communication was excellent with Sentinel. I messed up my impression the first time around but they were great about sending me another one right away. Recommended!!

  25. Shannon Goldstein (verified owner)

    Two thumbs up! Excellent

  26. Al McMurray

    I ended up leaving behind my night guard on a recent vacation in Hawaii. I called the hotel but to no avail. My dentist wanted 400 to replace it!! I couldn’t believe it. Sentinel was a really easy, and affordable solution to an unfortunate problem. Got the same exact night guard my dentist wanted to charge me 400 for at a fraction of the price. 5 STARS!

  27. Henry Witfield

    I was unsure if I could get a custom night guard online to help keep me from grinding my teeth. My Dentist quoted me $500 for a custom night guard and I decided to look online for another option. Glad I did.

    I Had my impression kit within 2 days after my order, from there it was really easy. It also came with step by step instructions on how to take my own impression, along with a website address of an instructional video (which I like since I learn easier visually). I mixed the putty and Took my impression and was done! sent it back in a nice little prepaid envelope they sent with the kit.
    Had my custom night guard within the week. FITS PERFECT! The night guard fit my teeth nice and snug but no added pressure or discomfort and I thought sleeping with guard would get annoying but I don’t even notice it, been sleeping better and my jaw pain has gone away.

  28. Roberta B.

    Love this night guard! Had to jump on here and give some feedback. From a person who was skeptical to buy online it was a nice surprise to get such a well fitting guard. I’ve gone through so many of these things (from my dentist unfortunately) and the quality is great. It fits perfect. These guys are good!

  29. Richard M.

    By far, the most comfortable night guards on the market. These guys take pride in their work and will work with you to your absolute satisfaction. A+++++

  30. Tracy C. (verified owner)

    I am a severe grinder and had an extensive amount of dental work to correct cracked and shortened teeth. I’ve even cracked crowns. I was a bit skeptical about Sentinel but figured it would save me a lot down the line since I average about a night guard every 18 months. My $650 custom night guard has hairline cracks all over after just one year. The process was thoroughly explained in the email and customer service has been excellent. It felt tight at first, but I’ve already gotten used to it after just 3 nights. Not only that I saved $$$, I don’t have to go to the dentist’s for fitting, which alone is a big hassle. I cannot be happier!

  31. C. Washington (verified owner)

    Snaps in place. Perfect fit! Thanks SM Team!

  32. Tinnia R. (verified owner)

    Customer service is on point! Well done Sentinel!!!

  33. Kai’Lyn Parinello (verified owner)

    I received my hard dental night guard & after two nights use I thought maybe I should have chosen the dual laminated guard. Contacted Sentinel & they happily complied with my request to change. By the time I received my new dual laminated night guard I had really adapted to my hard guard & decided to keep it after all (returned the dual laminated one). They were great through the process and went above and beyond to make a night guard that works for me. Highly recommended!

  34. Patricia K. (verified owner)

    Just wanted to let you know I love my mouthguard. Thanks so much! -Patty

    Thank you for your responsiveness and great service. Greatly appreciated:)

  36. John (verified owner)

    No complaints here. Price was righteous and works well even a year later. Looks professional/high quality and beats dental guards you’d pick up from a retailer like Walmart & CVS. Seriously, why buy junk like that when you can wait three weeks and get something fantastic that is fitted to your teeth and actually works!

  37. Emily Hill (verified owner)

    My nighttime grinding has not stopped ( I guess until there’s a cure this is as good as it gets) but I am at least grinding away on some durable material instead of my teeth. I have noticed my jaw & facial pain has stopped & I am grateful for the two year warranty on these.

  38. Fabian Morais (verified owner)

    I really like these night guards. I do not like soft floppy guards. They always seem to move around in the mouth and stretch out over time. These are hard and actually snap on to my teeth. The edges are smooth and not rough to the tongue or gums. This is my second guard from Sentinel and I ordered the 2mm. I would order more.

  39. Sammy U. (verified owner)

    Fantastic experience with a company that is on their game. Smooth, quick process. Even got a couple of night guard cleaning tablets in my package. Would highly recommend!

  40. A. Bushman (verified owner)

    I’d been using the standard night guard (purchased at CVS) but had trouble sleeping throughout the night. The store bought guard was soft & loose fitted. I was considering a high dollar night guard from my dentist when I read a thread on Reddit about Sentinel and the DIY impression system. So, I bought a kit and gave it a try using the putty and trays provided. Easy. Took a great mold of my teeth and got a great fitting, comfortable night guard. Since then, my wife and sister have both bought their own. Lucky to have stumbled across such a money saving alternative.

  41. Tori Allen (verified owner)

    I love this mouth guard because it is perfectly fit to my teeth. It feels great & not bulky at all. Love your service guys!

  42. Mrs. Catherine Russell (verified owner)

    The team at Sentinel was easy to work with and helped me with choosing which night guard was right for me promptly & painlessly. I’ve worked with them before about two years ago, and that was great too! Highly recommended.

  43. Matthew Silvestri (verified owner)

    Love this service. They’re honest and upfront about what they offer. I had a few questions in the beginning. Ashley and the rest of the staff were prompt and helpful.
    I got a great night guard for a portion of what my dentist was charging. Very thankful for this service. Kind regards, Matt

  44. Angelina Helfrich (verified owner)

    Thanks to the talents of the Sentinel team, a very hard, stable & durable night guard was made for my teeth so that I can sleep without having to wake up with the facial pain & headaches I was experiencing nightly. I feel good knowing my teeth are protected & at an affordable price. Muchas gracias for your generosity. *Angelina

  45. Tyler A. McCarthy (verified owner)

    Pros: thin and comfortable. The night guard doesn’t move around once it’s in and I can’t think of any way it could possibly fall out while I’m sleeping. Since it’s custom-molded it of course fit like a dream and works very well. Bottom line: this night guard is better than anything I’ve ever used and it’s 10 times cheaper than custom night guards made at the dentist office. I am happy to invest $150 bucks on something that protects my teeth from the damages caused by my grinding and the product is fantastic. Get one. You won’t be disappointed.

    Cons: These are very minor, and here is how I overcame these small issues: It took a little bit of work to get a deep teeth imprint when taking the dental impression. I realized afterwards that I just mixed the putty a little too long. So, this could have been prevented. Another thing, I used almost all the material and found that it was a bit too much once it had set but I have a small mouth.

  46. Hussein Y. (verified owner)

    Just received my dental guard and wanted to let you know it fits perfect! I was very nervous about using this system. Especially because in the past, the dentist has had to do some adjustments to my guard to get a great fit. This guard instantly snapped in to place. It’s thin and perfect. Thank yoU!

  47. Terrance Deacon (verified owner)

    Just reordered after my last Sentinel night guard lasted me 4 years. I ordered a 3mm thick one this time and hope to get even more years out of this new one. You have a customer for life and I recommend you to all of my friends & family.

  48. Dimitra Kosmakos (verified owner)

    Your site was the only one that offered the “choose your thickness” option.
    I am grateful for this, as I wanted two hard night guards in two different thicknesses. One to wear during the day and one at night. The process wan easy and I received my night guards yesterday. Both fit like a glove and I’m looking forward to ordering more in the future.

  49. William Bass (verified owner)

    Bill Bass here- Just wanted to check in and tell you all that your company is exceptional and the service you are offering is outstanding. I’ve been a loyal customer for 3 years and don’t plan on going anywhere. Gracias to you all.

  50. Anton Minopaulos (verified owner)

    Chose this guard because I needed a thin appliance to wear during the day. Asked for the guard to be made like my old dental retainer. I sent a picture in for reference via email and received a very nice, very thin retainer-like daytime guard. It is perfect. No one even knows I’m wearing it. I do take it out while I’m eating. My jaw pain from clenching has drastically reduced. Think I may order a thicker night guard for nighttime clenching next but this one has definitely helped my symptoms. Thank you!

  51. Janice K. (verified owner)

    Just wanted to let you know I received the 2mm night guard and it fits perfectly! Once again, I am very happy and satisfied with your service and Sentinel. Happy New Year and thanks again for everything!

    Excellent product. The night guard was a little tight the first couple of nights but now it feels really great. No more headaches from grinding teeth all night.

  53. Joanne C (verified owner)

    Have been using my 1st order for almost a year and they are great. Quality is the same if not better than the ones I got from the dentist!

  54. Jon Brock (verified owner)

    Excellent mouthguard. Does not bother me at night or slip out. Actually fits better than one I had made my dentist. Will definitely buy from Sentinel again.

  56. Tanya W. (verified owner)

    Thankyou. Your product is awesome. This is my second mouthguard (I lost the first ) and I have recommended you to Dentists and Doctors. It is so comfortable and unobtrusive.



  57. Liz Smentowski (verified owner)

    This is the best nightguard I have ever owned–better than those I paid $500+ for at the dentist’s. It’s thinner than I am used to which initially concerned me, but the material is extremely strong and durable, so the thinness ends up being a positive because it makes the nightguard less obtrusive and more comfortable.

  58. R Rambal (verified owner)

    I’ve had my guard for a couple of years and it still works for me…. I am a HEAVY grinder!!! Super comfortable, has held it’s shape perfectly, perfect fit. I will be ordering another one soon, just because I want to have a back up. Amazing product, for real. Incredible price, incredible product.

  59. Bella (verified owner)

    I purchased a hard acrylic mouthguard from Sentinel in 2015 and it still looks great. It fits better than a previous one that a dentist gave me. I sincerely recommend this company for their excellent service and for their low costs. Thank you, Sentinel!

  60. Janice K. (verified owner)

    I LOVE Sentinel mouth guards! I’ve bought from this company for 5 years – 1mm, 2mm, and 3mm (I’m a heavy grinder) and I’ve always had great service and quality products delivered to my door. For years dentist(s) wanted to charge me hundreds of dollars for just one mouth guard (ridiculous!) and I told them no way and ordered from Sentinel! Don’t let dentists talk you into super expensive mouth guards – Sentinel can make them for you at a fraction of the cost!

  61. Valerie Lauterbach (verified owner)

    This is a great service. The response time was excellent, the process easy, and the product just as advertised.

  62. Patrick (verified owner)

    Customer Service is A++. I have worn almost every single night for the past 3 years, and the product is still going strong.

  63. Tom Lundberg

    I have worn night-guards for over 20 years now, most made by my local dentist. These cost less than 1/4th the price, and are just as good a quality. The fit has been wonderful and I am going to order another pair.

  64. Christine (verified owner)

    I grind my teeth at night and in the day and I’ve worn through many night guards. This is the best one I’ve ever had, and it has cost me the least. I’ve had it for several years now and it hasn’t cracked, discolored or changed shape. I still have my wisdom teeth and Sentinel was able to get me a mouthguard that covered those as well.

    I like the night guard is clear, too. It’s easy to leave in Efferdent all day, daily, and it looks obviously clean. It still looks the same as the day I got it and it has definitely saved my teeth from cracking.

    I also like that the 2mm one is still fairly thin and I can fit it in my mouth. It doesn’t force my lips open at night.

    I’ve also been very happy with Sentinel’s customer service. They replied to me quickly and made sure that I was happy with my product. I plan to order more from them again.

  65. John S. (verified owner)

    I’ve had my Sentinel Night Guard since last July after the clicking in my jaw increased and it started to become painful opening my mouth all the way open; also was doing some pretty bad grinding. Although there was a hiccup of my order being processed in the listed timeframe, Sentinel was able to fix the error and rush the turnaround and get my night guard back to me pretty quickly. It has worked wonders and drastically decreased my clicking jaw and wear/tear on my teeth.

  66. Janice (verified owner)

    I LOVE Sentinel mouth guards! I’ve been ordering from this company for at least 5-6 years. Always quality products, wonderful service, and especially unbelievably great prices! Don’t pay the dentists’ high prices – buy from Sentinel and save money for the exact same thing your dentist makes – at a fraction of the cost!

  67. Allison Montgomery (verified owner)

    Where do I start? This mouthguard is by far the best I’ve ever had. Very professional process from start to finish. It is perfect. I did not think I would be able to wear a mouthguard comfortably throughout the entire night. I’ve never had such a perfect fitting, comfortable mouthguard.

  68. Nicholas Sabio

    I purchased a 1 mm bottom guard. The process was easy to take an impression. The guard itself actually fit very well and got used to it within a few nights. I tried others but they were way too bulky, not allowing me to sleep with my mouth closed. I have had this guard for well over a year and just now starting to see signs of wear. I will be ordering another.

  69. Paul Hopkins (verified owner)

    I’ve had bad TMJ for many many years. My dog chewed my last one. Customer service said this is common and that they’re attracted to the saliva? I don’t know but I wasn’t sure this would work for my TMJ because I’ve read that I might need a more complex appliance that moves the jaw into position. I’m happy to report that the hard night guard has offered much relief from my jaw pain and popping. It is comfortable and hard and offers the proper jaw support I need. I’m even happier to report that I saved hundreds of dollars. Much thanks to you guys!

  70. Thomas S (verified owner)

    I have been grinding my teeth at night for many years but had put off buying a night guard because of the high price my dentist charged for one. Back in 2015, I read rave reviews about Sentinel and decided to give the 2mm Sentinel Hard Dental Night Guard a try. The guard has worn a bit in some spots, but it is still totally usable and going strong more than 3 years later! I couldn’t be happier. Thanks Sentinel!

  71. Kathy Robinette

    Awesome communication. The mouthguard fits perfectly. Very comfortable. If there is a problem they get right on it. Couldn’t ask for a better company to purchase from and the mouthguard is very affordable. I love Sentinel Mouthguards.You guys are awesome.

  72. Patrick (verified owner)

    I really like working with sentinel, they’re fast friendly and follow up well. Any problems are cleared up with a no hassle approach. They make it easy when my dog chews my night guard! It’s not funny, but it’s funny cause it’s true.

  73. Leah Morris (verified owner)

    I am just writing to thank you for all the work you did to get me a mouth guard that fits comfortably.
    Sentinel mouthguard has great customer service. I had some problems with the original fit of my mouthguard, and they helped me return it 3 times and sent me a new impression packet. I am now completely satisfied with the fit. I would recommend them to anybody. Real value for the money!

  74. Robert

    They have a great product for a fraction of the cost that you’re dentist will charge. The customer service is outstanding, I had an issue and they took care of it immediately. They kept me informed during the entire process. I would recommend them to anyone.

  75. Ava (verified owner)

    I bought my night guard in June 2019 and found it to be a bit too tight in the front. I emailed them and they payed for shipping for it to be adjusted, then got it back to me is a very timely manner. The best part was that there were no questions asked! How refreshing, a company that honors its promises without attempting to scapegoat the customer! THEIR CUSTOMER SERVICE IS TOP-NOTCH and the product is great! Comfortable, effective and easy to use!
    Also, this is a family-owned business…all the more reason to purchase from them!! 🙂

  76. Mary Bedenborough (verified owner)

    This is a review about their customer service. This product just didn’t work for me. I have a very bad gag reflex and was unable to use the trays to take my teeth impressions. I opened and used the impression kit they sent out and called them to tell them that I couldn’t complete the process. They were so kind and issued my full refund immediately. Didn’t even have to send back the materials! Even though I didn’t end up getting a night guard, I was so pleased with the way they handled my issue. I will be back if I can ever get past this horrible gag reflex! Thank you again Sentinel. -Mary

  77. Kim (verified owner)

    I received my mouth guard and am very happy with the product so far.
    It was a bit nerve racking finding an internet company to fulfill this need. I’m glad I found Sentinel.
    I have been telling everyone I know about it and I’ve found most of my friends and family have mouth guards.
    I will continue to talk about it and hope to send some folks your way.

  78. Jerry Chua (verified owner)

    At first I bought night guards from Proteeth but these are much better.

    A few things to note:
    1. Don’t remove the putty from the tray after impression has been taken. Keep it in the plastic tray & mail the whole thing back.
    2. Mix the putty fast. I mixed too slow the 1st time & had to redo. They included an extra putty set so it wasn’t a problem.
    3. They offer free adjustments if its too tight.

    Really impressed with this product, incredibly easy to follow instructions and if you follow them, you’re left with a secure fitting, comfortable and perhaps most importantly a better nights’ sleep.

    I know another reviewer was worried that reboiling wouldn’t be effective since they might be similar to other mouth guard brands. That is true. You cannot boil the Sentinel Mouthguard. However, if you take your mold correctly you will not need to do anything but wear it. It wasn’t the most comfortable process but worked.
