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!

    Smooth running machine! I’d give Sentinel Mouthguards 10 stars if possible. My experience has been nothing less than fantastic. The staff is very friendly and helpful. They replied to my emails promptly and took the time to answer my questions thoroughly. I sent off my dental impression and received my custom mouth guard within a week. The fit is so comfortable. They have FAR exceeded my expectations. Well ran team!

  • SR Rehman

    I chose this company because I can customize the thickness. I only wear this for weightlifting so I didn’t want a bulky mouth guard..very happy with purchase.

    Great feeling mouth guard! I’ve had the boil types my whole life and finally treated myself to a custom mouth guard. I’m impressed by how nice these are. I definitely recommend!

  • Mike C.

    I rarely write reviews but wanted to say thank you. I screwed up my dental impression and even used the extra putty that was in the kit that was sent. Thank you for sending a new kit and not charging me. My mouth piece fits perfect and I appreciate your customer service. -Mike

  • Michael Pearson

    I can’t stand how bulky most mouth guards are. I perform better when my mouth guard is comfortable. What I love about these is that I get to choose the thickness. I went with a 2mm and wearing a mouth guard isn’t an issue for me anymore. Thank you and God bless!
