A professionally made sports mouth guard is highly recommended for athletes who play sports.

The Sentinel Sports Mouth guard is available in a wide range of colors.

When A Mouth Guard Is  Comfortable, It’s More Likely To Be Worn

We know that a lot of people avoid wearing mouth guards because they’re uncomfortable. They get in the way of speech, and sometimes hamper breathing. An improper fit can also put stress on the jaw.

As an athlete you should be focused on the game, not your mouth guard!

    I bought this guard for Jiu Jitsu training. I didn’t want a super thick guard and I love that this company give you the option to choose how thick it will be. This one is a 2mm. It offers solid protection. I can speak clearly and it does not fall out while I’m training. Had some trouble with the impression. Had to do it 3 times to get a good fit. I’ll say this: Be sure to get the gum line when you’re taking your impression. That’s what they’re looking for. They said mine was too shallow the first two times. Even though I had some fitting trouble I’m very pleased with the final product.

    I wasn’t aware of the difference between my boil & bite and a custom fit one. I was skeptical but the difference is unbelievable. Great mouth guards! *****

    When the mouth guard I got from my dentist wore out I decided to purchase another custom one but didn’t want to pay the dental office price. My gym recommended Sentinel Mouthguards. I failed at the first two attempts taking my impression. They were too shallow. The customer service rep actually called me to explain what they need from me and sent me a new kit for free. I did the third one correctly and received a great fitting mouth guard. I love it. I wear it all the time. The company made me feel like they really cared about my individual case. Best mouth guard. Don’t look any further! *****

    Being able to choose how thick these are is a plus.
    Needed two of these. One for MMA and one for weightlifting. I got a thinner one for weight lifting and a 3mm one for MMA. Fits well. Made well. I recommend.

  • John K.

    Great value for the low price. My dental office wanted to charge me $300 and I didn’t get an option to pick my thickness. I went with a 2mm thick guard because I’m not doing a full contact sport. Fits very well. Definitely recommend~

  • Tyrone Saterfield

    A good mouthpiece is everything. I can’t play right without one. I gotta be able to focus on the game and custom made is the only way I can do that. Love that fit!

  • Rico Hernandez

    Just bought two more for my little cousins for Christmas. I’ve had mine for about 5 months now. I used to go through the $5 ones every week!

  • Demetrius Condit

    Love the look and feel! I chose white. It’s thin and if you didn’t know any better you’d barely be able to tell I have one in. I got the thinnest one because I have a bad gag reflex. Impression putty process was easy. Will use again in the future!

  • Dan Mason

    Perfect fit. As soon as I tried it in I knew I made the right choice. Worth the money. Thank you!

  • Frédéric

    Its better 2 or 3 mm for the thick?

    • Asmi234

      Hi there!

      For full contact sports we suggest a 3mm thickness. 2mm is thin and best for non contact sports.
      Please let us know if we can help further.

    These Sentinel Mouthguards are without a doubt the best mouthguard I have worn. I’ve been a customer since 2013. They fit perfect and are unbelievably comfortable. The design is great and the color really pops. The quality of the material is very, very high and the quality of the overall product is extremely high. I will never purchase another brand of mouthguard. They are perfect to wear during Muay Thai, Boxing, MMA, Jiu Jitsu, Wrestling or any other kind of combat sport or just to work out in. A+++++

  • Vincent Giordano

    The best on the market!!
    I couldn’t pass on the great price these were being sold for. I followed instructions for taking my teeth mold they gave me and ordered a blue mouthguard. When I got the guard I knew it would fit well but the fit is far better than I imagined. It’s not too bulky. It feels good in my mouth. Very uncomfortable. Even wearing it while talking is easy. Again, very uncomfortable. Thank you.
