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.

    This is a great dental guard. Nice and comfortable. Big thanks! -Jim

  • Jessica E.

    We use these in our family. My mother wears one, myself and my husband. We are a family of teeth grinders! We love these night guards and the great team at Sentinel!!!!! So bright and cheerful, they are always there to help us. These guards lasts a long time. Will absolutely order more in the future.

  • Elissa Baker

    I clench my teeth a lot at work, and I’ve tried many night guards of all types.
    They never form well and they’re bulky. This night guard is nice. I can close my mouth, talk, drink water, etc.
    It’s the best of its kind I’ve used. I would highly recommend it.

  • C. Shultz

    I couldn’t find a night guard lab locally, so I purchased this one online & I’m so glad I did. I use this product daily and nightly. The material is soft, clear and unnoticeable. I went with the lower teeth guard. Impression process was easy. I made a nice mold of my teeth. The guard itself is sleek, slim and not too tight. Once I use this one up, I’ll definitely purchase this night guard again.

  • Jeffrey Warner

    I just received my 2mm soft night guard in the mail, and it is a perfect fit! As mentioned in other reviews, taking the impression was much easier than I thought, anyone with silly putty experience as a child can do this.

    After having paid my dentist > $600 for thses things in the past, I cannot ever imagine going anywhere else than Sentinel for these guards in the future.

  • Karen Honikel

    Fits very well. Wish the price was a little lower because my dog always eats my mouth guard so I have to buy them often.

  • Jennifer McClain

    I love my mouthguard from Sentinel. It is very comfortable, and I can’t sleep without it. I like that you can choose the thickness as well. It’s super convenient that they hold onto the mold so I can reorder when needed without having to make a new mold (although it is a very simple process to make the mold). I highly recommend Sentinel mouth guards.

  • BIll

    Easy fitting process and very comfortable to wear. Sentinel’s delivery was a little late, although the Company sent me two soft night guards for the price of one. Would definitely purchase again and recommend to my friends and relatives.

  • Phil P

    Excellent value. Fitting was easy. Just follow the instructions. The night guard arrived promptly and fit perfectly. Took a few nights to get used to wearing it, but now it’s the first thing I look for when I go to bed. I purchased a second one to use for traveling.

  • Ben

    Purchased several mouthguards over the years from Sentinal and aways been happy with the products and the service. Thank you! Ben

  • Ken Wright

    I am a pretty heavy grinder at night and my previous mouth guards I bought from my dentist @ a few hundred dollars per (and it last 6 months),and a sports equipment place.
    These folks were referred to me in a casual conversation from a friend as we were talking grinding, then cost from a dentist, and I mentioned I refuse to pay that ludicrous cost any longer, so I went with a off the shelf football mouth piece (which is not good for nightly use I am told, and it tears up my mouth
    I have ordered 2 guards to date and they are the same if not better quality than the dentist.
    My first one lasted about 8 months.( a bit longer than the dentist)
    I am on month 3 of my second one.

  • Linda

    Just as good as the ones they make in the dentist’s office and much less expensive
    I am on my 3rd Sentinel mouth guard in about 3 years. I purchased mine directly from the Sentinel website. Wearing this night guard has almost completely cured the constant tooth pain I used to have due to teeth clenching while sleeping. While these are much less expensive than the ones from the dentist’s office, they work just as well. The molding process is pretty easy but you have to be careful and follow instructions to get a good-fitting mold of your teeth. You also need to take care in cleaning the guard daily with some very mild soap and drying it well. My first 2 guards eventually discolored and stiffened up because I wasn’t cleaning them right. The latest one has stayed soft and supple since I stopped trying to use fizzy denture cleaner type cleaners. I soak mine in CLEAR mouthwash for 30-60 minutes or so after I take it out, then wash with warm water and liquid castile soap.
