Customer ratings & reviews

Excellent mouthguard. Does not bother me at night or slip out. Actually fits better than one I had made my dentist. Will definitely buy from Sentinel again.

Have been using my 1st order for almost a year and they are great. Quality is the same if not better than the ones I got from the dentist!

Excellent product. The night guard was a little tight the first couple of nights but now it feels really great. No more headaches from grinding teeth all night.

Just wanted to let you know I received the 2mm night guard and it fits perfectly! Once again, I am very happy and satisfied with your service and Sentinel. Happy New Year and thanks again for everything!

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.
