Customer ratings & reviews

Excellent value for the money. I was pleasantly surprised with how easy it was to take my impression. I remember the dental office impression process being messy but this was easy and straightforward. I honestly can't believe how well the night guard is working out. My dentist charges over $500 for a device similar to this one. So pleased with Sentinel!

I grind my teeth bad. My jaw can go from feeling awful to okay depending on the day or week.Even with pretty uncomfortable jaw pain, I still refused to wear a night guard. This went on for years. When I started getting sharp pains behind my eye I knew I had to do something. I tried the store bought ones. Waste of money. The Sentinel guard felt tight at first but now I'm used to it. My headaches and jaw pain are GONE! I wear it every night. It's truly made my life better. I feel younger strangely. Not in pain and grumpy. Thank you for making a life changing product Sentinel! I'm a customer for life.

I HIGHLY recommend this bite guard! I found this company, read all the reviews and ordered. Took the guard to my hygienist and she was impressed! I'm a customer for life. Considering ordering a second as a backup!

The process was simple, fast and the results were fabulous! The guards were high quality. My tongue has healed and currently I don't wear the guards as I don't need them. If I bite my tongue again, I will wear them to allow the area to heal. I am extremely pleased and would recommend!

My dentist had been recommending a night guard for my teeth grinding but I couldn't spend the money. Finally it got to the point where my teeth were wearing down, jaw was aching so bad, and I had headaches almost every morning. I found Sentinel online and the price is inexpensive compared to the dentist. I was sent a kit with the putty mixture and an extra set of putty in case needed. I took the impressions. FYI they make you take an upper and lower to check the bite before shipment. It took about a week and a half after I sent the impressions off to receive my night guard. It took me a few nights to get used to it but now I can't sleep without it! Wish I could give more than 5 stars. Excellent experience. Love that this is available to us as an affordable option.

My dentist told me I needed to be wearing a night guard during the day for my teeth clenching but could only offer me one of the bulky ones he sold at his office. No thank you! I did a search and selected this company on the basis of all the positive reviews. No regrets! I have only positive things to say about my experience. I received the kit and read the instructions carefully.I sent in pictures of two molds I took and the company representative helped me decide which one to mail in. The guard came and fits so perfectly. I wear it all the time. This is my first day guard and it has worked successfully. I highly recommend this guard!

GREAT MOUTH GUARD, FANTASTIC CUSTOMER SERVICE! When the mouth guard I got from my dentist wore out I decided to purchase another custom one but didn't want to pay the dental office price. My gym recommended Sentinel Mouthguards. I failed at the first two attempts taking my impression. They were too shallow. The customer service rep actually called me to explain what they need from me and sent me a new kit for free. I did the third one correctly and received a great fitting mouth guard. I love it. I wear it all the time. The company made me feel like they really cared about my individual case. Best mouth guard. Don't look any further! *****

GREAT PRODUCT AND SUPPORT! I tried to wear the boil & bite guards with no success. I grind and clench my teeth badly during the day and at night. Got this one for the daytime. Process was easy and guard is comfortable. Super friendly staff! Great buy!

Originally ordered these on Amazon and loooooved them. They fit so perfect Way better than the dentist made ones! My dog got a hold of them so I ordered a new pair. The company keeps the impressions on file for 1 year from the date ordered. I got a 20% off discount because I didn't have to take my impressions again. Second set came and it's identical to the first set! Consistent, excellent product. I highly recommend!

EXCELLENT QUALITY AND GREAT ALTERNATIVE TO THE DENTIST!!
