BEST MOUTH GUARD I HAVE FOUND! This is a 5 star product, way cheaper than the dentist and fits perfect.

Great price for a great product This is a fantastic find for a great price.

I researched a lot of other companies and they didn't require the upper and lower teeth impressions. I like that they make sure the bite is correct. I was skeptical because it's so much cheaper than the dentist but I got my guard and waited to weigh in. The guard fits perfect and I've been sleeping soundly for several weeks now. This is the real deal. Thank you for existing Sentinel. You're a tooth saver!

More comfortable than I expected! Extremely happy! *****

This is the only brand I trust. I've been a Sentinel customer for 10 years. Their customer service is great. They're consistent and I love their night guards. I have a no-show day guard that I wear during the day and the extreme durability guard at night. Nothing less than a positive experience for me. 5 stars!

Glad I gave them a try! It didn't work out for me at first because right after I placed my order, my tooth broke and I needed a new crown. I called them and they told me I could hang on to the teeth impression kit until my dental work was completed. Well, it took me 1 year to save up for the crown. I called and they still honored my order. That's what I call great customer care! I received my new night guard and it fits beautifully. Happy customer!

I have been having serious grinding issues since being locked at home- my teeth and surrounding areas including my jaw were in real pain every single day. My jaw would painfully pop when I ate anything or dared to open my mouth too wide- I was miserable. Bought way too many over the counter guards with minimal results. First use of the Sentinel guard and immediately noticed less pain- the very first night. I've stuck with it and all of my symptoms are near gone. This product works! I won't be going back to Walgreens. I'm sticking with quality.

I have gnawed through several of this online guards from different companies. I was about to pay $1200 at my dentist for a thicker one when I found the Sentinel team and decided to give them a try. The first impressions I thought were okay but they sent new impressions explaining that they needed a really nice impression to make a proper fitting guard. I retook the impressions. They didn't charge me for the redos. I got the guard back and it fit perfect. So far so good!

Those night guards at Walgreens are a joke compared to custom made guards. You can tell this guard is made from quality dental supplies versus the cheap plastic ones. This is durable and fits to my mouth perfectly. A+++

I was a little nervous when I ordered this because similar mouth guards have been uncomfortable, but I thought I would give it a try...what a pleasant surprise they are super comfortable! I ordered both a day guard and this heavy duty one. I love them and would definitely recommend.
