Product Description

Taking your own dental impression is EASY (and you do not need to pay a dentist hundreds of dollars to do it). We will send you a plastic tray, dental putty, & a prepaid envelope to mail back to us. You need to have a timer, clean hands, & good solid teeth. No braces. Seriously, putty & braces do not mix. We will give you a link to a video, pictures & written instructions to show how to mould and make sure it’s a good mould. All inclusive free shipping.

Here’s how it works: We mail out an impression kit to you (mixing putty & a tray). You take your own impression & using the prepaid envelope, mail it back to us. Upon receipt of your impression, we will fabricate your new custom fit night guard within 8-12 business days. That’s it!

.040 (1mm thickness) Ultra thin, hard 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.

.080 (2mm thickness) An added layer of thickness for extra durability. Ideal 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 dental 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”.

Our Commitment To You

The Sentinel warranty and return policy is unlike any other. We stand by our products and will always work with you to your absolute satisfaction. This means if you are dissatisfied with your product for any reason, you can either contact Sentinel within 90 days for a full refund or opt to continue working with us until you get a great fitting guard.

    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

    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+++

    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!

    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!

    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.

    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? hehee
    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 and save some dough! We are real people who had a great experience!

    I never write these things because I never really care to, but Sentinel really hooked me up. They were really nice on the phone and helped me through the whole process of picking the right guard, shipping, taking my own impression etc. I choose the .40 because I wanted strength but wanted to keep it thin in my mouth since I’m a light sleeper. This company is very professional, thanks for everything.

    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.

Kudos!

    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:)

    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!

    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!!

    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!

    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.

    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!

    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!

    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!

    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!

    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.

    (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.

    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.

    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

    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.

    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!

    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.

    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.

    THE 1mm THICKNESS IS PERFECT FOR DAY USE!!
    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!
