Product Description

Product description

The Sentinel soft dental guards for tongue & cheek biting 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.

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.

  • James P. Murphy

    Soft, thin and comfortable! A+++++

  • 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.

  • 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.

    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.

  • 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.
