Customer ratings & reviews

Love the free shipping and these are the best prices on the internet. I've been through other companies and you guys ROCK!

This is a lifesaver for me! I was cracking my teeth and having horrible jaw pain. The store bought guards weren't cutting it and the dental office price is unbelievably high. I chose Sentinel Mouthguards because of the price point and the 1 year warranty. So glad I did. Absolutely terrific company with a great product!

I bought this night guard for my son who grinds his teeth. We unsuccessfully attempted the first mold but Sentinel sent another kit out right away. So happy I could get this mouthguard at an affordable price. My dentist wanted to charge a small fortune! Thanks Ashley & the rest of the staff. You guys are great!

EXCELLENT!! I didn't get my impressions right the first time and I used up the extra putty. They sent me another kit free of charge! I sent in photos and they were accepted. Company has great customer care and the retainers fit like a dream!

Perfect fit. As soon as I tried it in I knew I made the right choice. Worth the money. Thank you!

Sentinel is really great! The process was easy, the shipping was really quick. Upon receiving my guard, I used it for two nights and it was slightly uncomfortable in one area of my mouth. I realized it was because I probably didn't do the imprint process correctly. I contacted Sentinel, they adjusted the guard and sent me a brand new one. This one is perfectly comfortable and allows me to sleep well at night. No more grinding my teeth and I feel healthier already. Thank you to the team at Sentinel for hooking if up!

Great for teeth grinders! I needed a mouth guard for sleeping that wouldn't be too big and uncomfortable that I take it out during the night. Wanted one just for the top teeth and less bulky than the one I got from my dentist. Tried the OTC ones and I just remove them during the night, or they cause my teeth and jaw to hurt by morning due to the imperfect alignment. THIS ONE IS PERFECT. I read some reviews that said it was difficult to take the impression, but I watched the YouTube video and got it perfect the first try. Follow the instructions, use a mirror to place it and you won't have a problem. It is not necessary to bite down hard into the plastic when taking the impression. Really just stay focused on getting a good, even impression. Seems like a lot for a little piece of plastic, but my dentist wanted to make me one for $800, so this was a much better deal. And best part, woke up without a headache for the first time in years. Cheers!

Amazon Review 5.0 out of 5 stars Great Affordable Mouthguard Process was easy and normal shipping speed. I had trouble making good impressions but Sentinel Mouthguard's was able to send me new molding clay without extra cost. Fit beautifully. -L. Bryant
