Great Night Guard, Read the Instructions! This is probably one of the best night guards for me that I've used thus far. I purchased this to help with my teeth grinding, but have found it extremely helpful for snoring too. I'm satisfied with the product and will order another when the time comes. Thank you!

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.

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.

EXCELLENT QUALITY AND GREAT ALTERNATIVE TO THE DENTIST!!

Much less expensive than the dentist yet seems to be the same quality. Headaches and jaw pain have gone away! Easy set up.They provide you with simple instructions. I recommend!

This mouth guard is amazing. I grind my teeth very heavily during both the day and night though I think I'm clenching more during the day. Brought this into my dentist appointment assuming he was going to tell me it was no good and to buy his $800 mouth guard from his office. He looked at it both in and out of my mouth and said it's a "very well made guard." I've tried many store brand mouth guards and bit right through those within months. Sentinel will be my go-to brand from now on.

Great mouth guard! Extremely sturdy and high end.

This is it! Best night guard and great customer service!! A high quality custom made night guard for this price? This is fantastic and just what I've been looking for. I have only used it a few nights but this is awesome so far. If this works well and lasts, you have a customer for life!

Customer service is outstanding! Suzanne was there to answer all of my questions beforehand. Very happy with my purchase. Will recommend! *****
