THE 1mm THICKNESS IS PERFECT FOR DAY USE!! Chose this guard because I needed a thin appliance to wear during the day. Asked for the guard to be made like my old dental retainer. I sent a picture in for reference via email and received a very nice, very thin retainer-like daytime guard. It is perfect. No one even knows I'm wearing it. I do take it out while I'm eating. My jaw pain from clenching has drastically reduced. Think I may order a thicker night guard for nighttime clenching next but this one has definitely helped my symptoms. Thank you!

Bill Bass here- Just wanted to check in and tell you all that your company is exceptional and the service you are offering is outstanding. I've been a loyal customer for 3 years and don't plan on going anywhere. Gracias to you all.

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!
