Product Description

Product description

The Sentinel Tongue and Cheek Biting Relief Guards are designed for comfort, ease of wear and effective protection from the damages that result from tongue biting during the night or day. Our high polishing system and thin design ensures a supreme fit.

What material is used?

We use BPA free soft material to create your upper and lower custom made guards. The material is high quality, dentist-grade EVA (ethylene vinyl acetate) and intended for daily oral use.

How does it work?

Your upper and lower guards are to be worn at night or during the day to protect your tongue from damages associated with nocturnal/nighttime or daytime tongue biting. The soft padding on both the upper and lower teeth prohibits direct tooth to tongue contact thus preventing damage.

What you get

  • We will send you a dental impression kit which includes 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.
  • (1) upper and lower set of soft custom guards
  • Ventilated retainer case

Many people search the internet daily in hopes of finding a product that will protect their tongue or cheeks from damage associated with tongue and/or cheek biting. The Sentinel Soft Dental Guards are made to fit your teeth like a glove. The soft padding disallows the chewing surfaces of the teeth to catch the tongue or cheek area. The product will prevent any trauma to the tongue or cheek area and will allow any previous trauma to heal.

Product Reviews

  • Lawrence Anderson

    The product fits great! I’ve slept with it for about a week now and so far so good. I do bite my cheeks a little but I’m mainly using these as teeth protectors for my grinding and clenching. I’m hoping they hold up over time because they are soft and a little flimsy.

  • Terry Taylor

    Can’t believe I’m writing a product review for my tongue biting problem. But here goes.

    This is the most comfortable mouth guard set I’ve ever worn ever. I am so impressed by this brand. The customer service was extremely helpful over the phone. The entire process was quick and easy and the mouth guards are a perfect fit. This is a wonderful product!

  • J. McCoy

    They sent me the impression trays and putty, and I chose the correct tray size. The smallest tray was too small and cut off my molars. Took my impressions and mailed it off. The teeth guards arrived within 10 days. I popped them in and they both fit like a glove. It works GREAT and I have no soreness. I’m 69 and thought I would never get used to wearing these. I am keeping this product as I am very satisfied.

  • R. Bachelder

    I’ve never used a mouthguard before so I was fearful of purchasing two to wear at the same time, but my dentist recommended buying this so here I am. I’m planning to use a set of the spare guards next week as a teeth whitening tray too, I’ll be curious to see how it works. Overall I’m pretty satisfied so far. It does the job.Thinner than I anticipated.

  • Amy W.

    Great for cheek biting protection, not great for teeth grinders.

    The thin soft plastic is like the teeth whitening trays I got custom made at the dentist years ago. It’s comfortable but I grind my teeth too so I wore a hole through the plastic within about a month. They did replace it for me which I appreciate. There’s a 6 month replacement warranty of you wear through the guard. They do not cover heat damage like if you left it our in your car and the heat warps it so keep it in the AC. Thinking about getting a thicker night guard for my top teeth and still wearing my thin lower guard so that I don’t keep grinding holes through it!

    Excellent experience all around! The customer service stood out to me because they’re so personable. I talked to two different people and both were very helpful and great communicators. I explained my problem. I bite my cheeks excessively and I did not know there to turn. They made me feel confident to choose Sentinel. I’m so glad I did. The guards are well made and work as intended. My damaged area has healed up and the pain had gone away. Much much appreciated and recommended.

  • George Talaiver

    Love it. Have stopped teeth from damaging my tongue.

  • Larry Lerche

    I screwed up my dental impressions. Both of them. I took too long to mix the putty both times. Guess I’m bad at reading directions. The company did send me a redo kit free of charge. I was successful the second time around and got my guards. They really do fit like a glove and my tongue is healed! I highly recommend your company! A+++++

  • Elijah Hawley

    I’m putting the review here because this is the intended purpose. That is, to stop my cheek biting but I actually ordered the hard dental retainers for this and it works exceptionally well. I don’t know if anyone else has ordered the hard ones for cheek biting but they work too. Basically, the plastic surface disallows the cheek to “catch” between the teeth. I’m sure the soft ones are fine.

  • William E.

    This has been a problem since I was a kid. I bite the inside of my cheeks until they bleed. I do it in my sleep so I am unaware of it. I’ve tried a lot of methods to stop the cheek biting. I think I do it more when I’m stressed. I bought these dental guards because I can’t seem to stop on my own. I can sleep with them in comfortably. I can’t tell you how nice it is to finally have my cheeks healed up. I would highly recommend this product for anyone that has the same issues as me. 10 stars!!!!


  • Justin Caldwell

    This is the first product I have found that actually works! I am a chronic tongue biter and have damaged the edges of my tongue. My tongue bleeds and is very painful. The soft dental guards are comfortable. It took me about a week to get used to sleeping with them comfortably. They are thin and my tongue has quickly healed. I cannot express my gratitude and the relief I feel. Thank you!

  • Vivian Frances

    My daughter has seizures and has had terrible pain from biting her tongue during her episodes. I searched for a long time to find something that would help her. The dental impression process was very easy to do. I helped her with her impressions and we received two very well made soft night guards. She wears them nightly just in case she has a seizure. So far so good. They’re very thin and soft yet firm and I feel better that she has something protecting her from damaging her tongue any more.
