"Should I Choose an Upper or Lower Night Guard?"

Most of the time the decision boils down to preference. For more guidance, click on this article about choosing the upper teeth or lower teeth dental night guard

Have some additional questions about ordering your night guard?  We've got you covered. Your most FAQ's about night guards for teeth grinding.

Here's a tip when deciding on which night guard is right for you:

Remember that if you do not wear your night guard for a while your teeth may naturally shift overtime. This can cause your night guard to fit incorrectly. So, if you do not wear a night guard often (consistently), it's probably better to choose the Sentinel Soft Dental Night Guard.

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 mold, and make sure its a good mold. All inclusive free shipping.

    Company was kind and cooperative when I messed up my dental cast the first time. Word to the not-so wise, be careful about your time when mixing the putty. I mixed mine for too long and it hardened before I could even sink my teeth. Second time was much easier. Received my Sentinel guard today. Really nice quality. Fits well.

  • Camden McCrary

    What a delight to find a company that doesn’t want to take every dollar you have. These guys are not solely about profit. They give a damn and it’s obvious. Huge thank you to you all. Thank you for making this affordable to the people who don’t have deep pockets. Love my nighttime guard. Will recommend this to everyone I know. *****

  • Torry Henderson

    I recently started biting my tongue and inside of my cheeks during sleep. Frustrated, I made an appointment with my dentist who said I needed both upper and lower bite guards to prevent any further damage. His quote was $700 for the set. I couldn’t pay his price and was so relieved to find this website. I got both for around $160 using the “big spender” discount code. They fit great! I chose the 1mm thin ones and they’re not bulky at all. Glad you guys exist for poor folks like me! 😀 I’ll recommend you to everyone I know!

  • Barbara Curran

    These are fantastic, well-made, shock absorbent night guards. After multiple uses now, my headaches and jaw pain are non existent. I just don’t seem to have any issues anymore! Thanks for the excellent service you provide.

  • Marion Cook

    What a relief – excellent bargain, much faster than the dentist’s office, easy to follow instructions, seller easy to contact and very helpful – highly recommend. Thank you and I’ll be purchasing again with you when this one needs replacing in a few years!

    ‘ve bought 6 of the Sentinel soft nightguards over the years for myself and various family members. They last for years, and if you buy more than one they get cheaper. Some people can buy generic nightguards, but I need ones fit to my teeth. You can go to various doctors and get customized nightguards, but if you can follow simple directions you can get a custom fit at home using this method. I was nervous I’d screw it up the first time, but they have always come out right. I had serious bruxism for years, and tried most everything. I am convinced that these nightguards, combined with changes in habits have been instrumental in mitigating my pain. Of course every case is different, but I swear by these.

  • David Etter

    Where do I start? Not only do I have an HSA account and was able to get this purchase covered by just sending in a copy of my invoice but I have never had a more comfortable night guard. I’ve been through so many dentists and night guards over the years. These guys are pro! BIG THUMBS UP!

  • Candace Herndon

    I didn’t think the nightguard would be as wonderful as it is because of the price, but after 3 weeks of using it, I don’t think I’m ever going to use my old ways of paying $500 to the dentist ever again. The material is soft and bendable. I chose the 1mm and it is thin, easy to sleep in and gets the job done. Be careful to watch your mixing time when mixing the putty for your dental impression because it dries up pretty fast. After I took my first impression, they had to send me a replacement kit to take the impression again. Definitely a steal at this price.

  • steven

    First, I do not like to buy things that I am not able to test before buying. We did buy these based on the most recent reviews on this product. I have had this dental guard for two weeks and it is GREAT! So much relief to find a superior product for way less than what my dental office was going to charge me.

  • Charlotte Devereaux

    I messed up badly with my order: I ordered a sports mouthguard instead of a nightguard, the wrong size as the plastic mold was too big to fit in my mouth, and I even messed up my print. Ashley from customer service was my saviour: she overnighted me a new mold, new putty, and when I received the nightguard, she even sent me the sport mouthguard replacement. Very high quality service. Praiseworthy!

  • Mary D.

    I reached out to Sentinel about my teeth grinding issues. The Livechat operator was very informative. Instead of trying to sell me on their more expensive services, I was instead told that I was already in pretty good shape and did not need to spend the money on the more expensive mouthguard types. I received my Soft Dental Night Guard in the mail and I can’t explain how nice it is to wear an appliance that is custom made for you vs the store bought kind. Very happy customer! Thanks!

  • Kelly Chadwick

    I love that I got to choose my thickness. I cannot sleep with anything thick in my mouth and the 1mm worked perfectly for me. Thanks
