Customer ratings & reviews

This product saved my cheek!! It was such a disaster. I could barely eat and I kept accidentally biting it to the point that I thought I may have to have surgery. The guards kept me from biting and the damage was noticeably better after just a couple of days. Life saving product!! Thank you. Thank you. Thank you!

This is my 2nd Sentinel night guard and I will never buy from my dentist again. He charged me $550 every time I went in for a new one and they never lasted more than a year. I will be a long time customer and will continue to recommend Sentinel Mouthguards.

I used to buy one of the drugstore mouth guards every couple of months and I'd wear a hole through it in no time. This is not the case with these custom made ones. The quality of the plastic is higher and much more durable. Still less cost than the dental office versions. I will order from this company again. Best mouth guard ever!!

Great company! Great product! I highly recommend Sentinel Mouthguards!

Best sleeping night guard I've ever used Much easier to sleep in than the one I got from my dentist. It's still thick but much less bulky if that makes sense. May purchase a second one while it's at this price (dentist charged $500).

I have an obsessive compulsive disorder that makes me repetitively bite the inside of my mouth. I've gone to doctors, taken medications, tried to lower my stress levels, all the things that they say to do and none of it worked. The tongue and cheek biting guards are the only thing that has made a difference for me. The process was a little longer than I hoped for but at the price I guess it's a lot better than going to the dentist. I'm happy to have found a solution and I highly recommend. Customer service is very nice too.

Didn't work out for me. I found out I needed extensive dental work after I ordered. Contacted the company and told them my situation. They issued my refund immediately. Suzanne is the sweetest! Thank you for making this easy for me and once I have all of my work completed I will definitely be back!

These are custom made and fit like they are exactly for your teeth. They are thick enough to be durable for a heavy teeth grinder like myself and I was happy to learn that they are the safest night guard online. Staying away from BPA, MMA and Pthathlates is very important to me. They seem to keep the shape well as it's been about 6 months since I ordered and still fits like a glove. I'll update if something changes. I am using this for severe nighttime teeth grinding.I am very happy with this purchase and will be buying them again!.

I've given 5 stars and if I could give more, I would! I love Sentinel Mouthguards; their customer service, this product (it's the only one that I've found that actually WORKS) and the timeliness of the experience. The teeth impression instructions and extra tips are fantastic and very easy to follow. The customer service team is so lovely. I gained instant confidence in this company as soon as I had a chat. The product is great and brought so much relief to me. I'm grateful <3 Thank you!

I found this to be perfect for so many reasons. 1st I found these to be so helpful when I realized I was suffering massive headaches during the day from clenching my teeth. I found the day guard and then later saw that they had other varieties as well. The 3mm hard night guard is perfect for my nighttime grinding and I wear the thinner day guard at work. Being able to have them both and save a lot of money is wonderful. I got 20% off my thicker nighttime guard because the lab already had my impression on file. All you have to do is ask for the coupon code! I highly recommend these!
