Pros: thin and comfortable. The night guard doesn't move around once it's in and I can't think of any way it could possibly fall out while I'm sleeping. Since it's custom-molded it of course fit like a dream and works very well. Bottom line: this night guard is better than anything I've ever used and it's 10 times cheaper than custom night guards made at the dentist office. I am happy to invest $150 bucks on something that protects my teeth from the damages caused by my grinding and the product is fantastic. Get one. You won't be disappointed. Cons: These are very minor, and here is how I overcame these small issues: It took a little bit of work to get a deep teeth imprint when taking the dental impression. I realized afterwards that I just mixed the putty a little too long. So, this could have been prevented. Another thing, I used almost all the material and found that it was a bit too much once it had set but I have a small mouth.

I didn't think the nightguard would be as wonderful as it is because of the price, but after 3 weeks of using it, I don't think I'm ever going to use my old ways of paying $500 to the dentist ever again. The material is soft and bendable. I chose the 1mm and it is thin, easy to sleep in and gets the job done. Be careful to watch your mixing time when mixing the putty for your dental impression because it dries up pretty fast. After I took my first impression, they had to send me a replacement kit to take the impression again. Definitely a steal at this price.

Exactly what I needed! Thank you so much! -Heidi

This is a great product. It is very easy to make the mold and took all of three minutes to form, submerge the teeth and let harden. The night guard is top-notch and the material is comfortable to wear for long periods of time.

Thanks to the talents of the Sentinel team, a very hard, stable & durable night guard was made for my teeth so that I can sleep without having to wake up with the facial pain & headaches I was experiencing nightly. I feel good knowing my teeth are protected & at an affordable price. Muchas gracias for your generosity. *Angelina

Aside from unbeatable comfort, the second best aspect of the Sentinel mouth guards is that you can customize them to any color you desire. You can have your name imprinted on them or your team name and colors. I still have my first mouth guard that I ordered from Sentinel in 2011 (just a plain dark blue) and just had a second one made in honor of my dad. I recommend you guys all the time. You're the best!

First, I do not like to buy things that I am not able to test before buying. We did buy these based on the most recent reviews on this product. I have had this dental guard for two weeks and it is GREAT! So much relief to find a superior product for way less than what my dental office was going to charge me.

Love this service. They're honest and upfront about what they offer. I had a few questions in the beginning. Ashley and the rest of the staff were prompt and helpful. I got a great night guard for a portion of what my dentist was charging. Very thankful for this service. Kind regards, Matt

I messed up badly with my order: I ordered a sports mouthguard instead of a nightguard, the wrong size as the plastic mold was too big to fit in my mouth, and I even messed up my print. Ashley from customer service was my saviour: she overnighted me a new mold, new putty, and when I received the nightguard, she even sent me the sport mouthguard replacement. Very high quality service. Praiseworthy!

The team at Sentinel was easy to work with and helped me with choosing which night guard was right for me promptly & painlessly. I've worked with them before about two years ago, and that was great too! Highly recommended.
