A professionally made sports mouth guard is highly recommended for athletes who play sports.
Mouth guards should be worn during training as well as during games.
The Sentinel Sports Mouth guard is available in a wide range of colors.

The cost of a custom mouth guard is a small fraction when compared to the cost of dealing with dental trauma.
Up to 40% of dental injuries are sustained during sports activities.

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!

    Dentist wanted $350 for this same exact guard. A buddy of mine told me about your company. Excellent service, affordable quality product. Satisfied customer!

  • Derrek P

    Fast shipping and very easy to deal with it. Extremely happy with Sentinel
    Well done! A+++

  • Colt Gardner

    Got my mouth guard today. I’ve never had a better fit. It’s not bulky at all. I can talk with it in, & drink water. Can’t wait to use it at practice tonight! Thanks Sentinel!

  • Abram A.

    Had a little trouble getting a good mold of my teeth the first time around but Sentinel sent me another kit right out. I had been using cheap store bought guards for years. I’ll never wear anything but custom from now on. Huge difference.

  • Eric Ro

    This is my first time using Sentinel but my 4th custom Mouthguard and its by far the best one out of the 3 that I’ve had.. Hands. down. Its not super bulky or cheap feeling. My others would hurt my mouth after about an half an hour from being stretched out. I can breath a lot better, I can drink water without taking it out, and I can speak clearly. I highly recommend Sentinel.

  • Jacob H

    I wanted a better mouthguard than a store bought one to use while playing hockey, I kept gagging on my boil and bite when I would skate hard and its started to get really annoying. My buddy told me he got one from Sentinel and to try them out. Happy I did, totally worth it! its fits great and easy to breathe!

  • Catarina Jenkins

    Was nervous I wouldn’t be able to take my own dental impression but after being quoted $250 at the dentist I thought I would give this a try. So glad I did! Best mouth guard I’ve ever owned!!

  • Suzy Slasher (ECRD)

    I play roller derby and we have to be able to communicate. Also, we get in trouble if they catch us taking our mouthguard out (which is inevitable if its uncomfortable). I’ve gone through so many brands and Sentinel is by far the best. Through and through just a great company. The customer service was perfect, professional packaging, instructions that make sense, and a quality product. Couldn’t ask for more. Good job guys!

  • Chris MMA

    100% perfect fit. Such a difference from my other one. WoW! Thank you!

  • Demarcus QB

    Friendly staff and quality mouthguards. Both thumbs up!

  • unknown

    I’m saving up for the full wrap design but for now just to have a quality mouthguard is enough for me. I absolutely love it! Will be back for more!

  • Lionel Briggs

    Sentinel mouthguards are the best! Almost our entire team wears them. Keep kicking Arse!
