Customer ratings & reviews

This was easily the best online purchasing experience I've ever had. My night guard is extremely comfortable; Sentinel worked with me until the fit was just right. Their customer service is fantastic. The product is also considerably more affordable than I was quoted at the dentist, and the dentist himself was very impressed with the quality when I took it in to reassure him I had found a legitimate lab to make one for me. Honestly, if you need a night guard don't hesitate; you're not going to find a better deal or a better product.

Bought these for my daughter. Nice customer service and nice product. Very easy to work with and at a fraction of the dental office cost. I'll take it :D

I absolutely love this product. I recently had to switch to the hard dental retainers because I made a mistake when I ordered and bought upper and lower soft night guards instead. Much to my disappointment, the soft night guards arrived and obviously did not help keep my teeth straight. I contacted Sentinel Mouthguards and explained the error. Customer service was excellent and the lab very quickly made my hard dental retainers and mailed them to me within a few days. They fit perfectly. They're made extremely well. I wear them during the day & night. Very satisfied customer!!

I LOVE Sentinel mouth guards! I've bought from this company for 5 years - 1mm, 2mm, and 3mm (I'm a heavy grinder) and I've always had great service and quality products delivered to my door. For years dentist(s) wanted to charge me hundreds of dollars for just one mouth guard (ridiculous!) and I told them no way and ordered from Sentinel! Don't let dentists talk you into super expensive mouth guards - Sentinel can make them for you at a fraction of the cost!

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 purchased a hard acrylic mouthguard from Sentinel in 2015 and it still looks great. It fits better than a previous one that a dentist gave me. I sincerely recommend this company for their excellent service and for their low costs. Thank you, Sentinel!

Got this for my wife. She loves it. Says her tension headaches are not there anymore. Took some initial getting used to but she adapted and loves it. 5 stars!!!

I love my mouthguard from Sentinel. It is very comfortable, and I can't sleep without it. I like that you can choose the thickness as well. It's super convenient that they hold onto the mold so I can reorder when needed without having to make a new mold (although it is a very simple process to make the mold). I highly recommend Sentinel mouth guards.

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.

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.
