    Great fit!

    This is the best fitting night guard I've ever had. I think it's a great price for the top quality & fit. The customer service is wonderful. I had questions, and they were all promptly fully answered. I found the impression process easy. The instructions & video were simple to follow.

    3rd times the charm

    I first tried the a boil and bite night guard and then a disposable partial night guard. The boil and bite was too big in my mouth and caused jaw soreness over time. The partial caused minor tooth aches as only a couple teeth were covered and took all of the grinding pressure. The sentinel night guard was a completely different. It was way more comfortable and I did not have concerns of it shifting my teeth or hurting my jaw. It did take me 3 attempts to get a good mold but customer service was quick to review pictures to identify problems before I shipped my mold. Watch the videos of how to do it properly and you should be ok. I am confident I would not have molding issues in the future now that I understand the proper way to form the mold.

    Excellent Fit, Quality, and Customer Service

    I absolutely love this night guard! I had a small issue with the fit of my first one, but Sentinel immediately sent me a replacement that was perfect. The customer service was great and the product itself is excellent. This is actually my 4th night guard, and I’ve usually gotten them from the dentist for $200+and honestly, those weren’t even as good as this one. I paid a fraction of the price and received the best-quality night guard I’ve ever had. Highly recommend!

    Highly Recommend

    I’ve used Sentinel night guards for several years with great success. Easy company to work with. Their product is excellent. Price very affordable compared to guards purchased through dentist.

    Fantastic price, more minimalist than bulky

    I’ve used custom night guards for years. I’m used to them being a bit more bulky and was surprised when this one looked so minimalist. It took me a little while to get used to it but it has been great! I like that it’s not as bulky and does the job just fine.
