Customer ratings & reviews

They have good service. The 1MM night guard is very comfortable, and when it wore through, they replaced it at no charge. And you can't beat the price - oddly, my dental insurance does not cover night guards. The ones offered at my dentist's office are way too expensive.

I am downright STUNNED at how well this night guard fits. Buying a night guard is typically a recipe of sadness for me when ordering online, but I took a chance. It is AMAZING. It is a nice thickness and the teeth do not feel constrained. The guard is a little bendy which is nice and the look of it is exactly what is pictured in the product images. I love that this is BPA free too. The inside part is soft and the hard outer lining feels good. It looks and feels outstanding. The only concern I have is that when cleaning I noticed the two layers are visible. I can see where the soft meets the hard and I wonder if this may be prone to separating. I contacted the company and they said this is solved by being sure to keep the guard completely dry between uses and store in the dental case provided. So far so good. I might eventually buy another as a backup but for now, I am left 100% satisfied and amazed at the overall experience.

I've been using Sentinel night guards for several years now. Their quality night guards have helped reduce wear on both my enamel and my expensive veneers. In fact, I've had no breakage whatsoever since using their product. But the best part of Sentinel is their customer service. Any time I've had a question or a concern, they have been super quick to respond and remedy the issue. The warranty period on their products is very important to me. And any time I've worn through a night guard that is still within the warranty period, Sentinel has replaced it free of charge. I plan to have more dental work done in the near future, and without question I will be placing a new order through Sentinel.

This is by far the best mouth guard I’ve ever owned! I bought one from my dentist last for 3 times the price and 1/2 the quality of Sentinel mouth guard! It lasted less than 6 months. I like to use the product I buy before I leave a review and I have used this one! Every night for the last 2 years and occasionally during the day if I’m grinding my teeth due to stress. I have the dual guard that is just starting to show enough wear that I need to replace it. I will never use any other mouthguard! Sentinel is the best!

Thank you for your comfortable dual laminated night guard and fabulous customer service with Ashley. I once spent $700 for a TMJ splint that lasted less than 2 years. When it cracked in half, I freaked! Then I found Sentinel Mouthguards online and was so relieved that I could get a professional custom-made nightguard for $129! Great deal and a good quality product. I took it to my dentist to check the fit and he approved! He said even HE grinds his teeth at night! (I recommended Sentinel. LOL!) Taking the impression was so easy and it's great knowing they can make a future guard from my impression. As far as customer service, they really stand by their product. When my first night guard split after only a year, they honored their guarantee and sent me another. What can I say other than you guys ROCK! I'm so thankful that you're here. I couldn't live without my Sentinel Mouth Guard!

LOVE it! Entire process was easy. The mold fits perfectly! Good job! I have worn a night guard in past which was ordered from my dentist at the much higher prices, and this Sentinel guard is even better than that one. I ordered the 2 mm dual guard. I barely notice it in my mouth and it fits snugly. I also am thankful it's BPA-free. Highly recommended for protecting your pearly whites!

Hey guys, I've loved the nightguard so far - it's the most comfortable one I've ever had, and I now rarely find myself having dreams where I'm pulling hard candy or gum out of my teeth! Jeremy

Sentinel Mouthguards were great and very responsive to my emails when I messed up the first package they sent me. The second one was just as quick in arriving and the final mouthguard was as well. I have only good things to say about this company.

I just received my night guard and it fits perfectly. I am going to order a second one to have on hand because I travel a lot...this way I can keep one at home and one in my luggage. The process was easy and quick, except the return was delayed by USPS. When I talked to my dentist about needing a night guard they quoted almost $700 for one and I will pay under $150 for two. Also a co-worker just ordered one from her dentist for over $800. This is the way to go if you need a night guard and if you have a Health Reimbursement Account you can use that to pay for the guard. I would recommend this to anyone looking for a quality product (same as you get from the dental office) for an affordable price.
