Your site was the only one that offered the "choose your thickness" option. I am grateful for this, as I wanted two hard night guards in two different thicknesses. One to wear during the day and one at night. The process wan easy and I received my night guards yesterday. Both fit like a glove and I'm looking forward to ordering more in the future.

Just reordered after my last Sentinel night guard lasted me 4 years. I ordered a 3mm thick one this time and hope to get even more years out of this new one. You have a customer for life and I recommend you to all of my friends & family.

Just received my dental guard and wanted to let you know it fits perfect! I was very nervous about using this system. Especially because in the past, the dentist has had to do some adjustments to my guard to get a great fit. This guard instantly snapped in to place. It's thin and perfect. Thank yoU!

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.

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

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

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.

I love this mouth guard because it is perfectly fit to my teeth. It feels great & not bulky at all. Love your service guys!

I'd been using the standard night guard (purchased at CVS) but had trouble sleeping throughout the night. The store bought guard was soft & loose fitted. I was considering a high dollar night guard from my dentist when I read a thread on Reddit about Sentinel and the DIY impression system. So, I bought a kit and gave it a try using the putty and trays provided. Easy. Took a great mold of my teeth and got a great fitting, comfortable night guard. Since then, my wife and sister have both bought their own. Lucky to have stumbled across such a money saving alternative.

Fantastic experience with a company that is on their game. Smooth, quick process. Even got a couple of night guard cleaning tablets in my package. Would highly recommend!
