One word- PERFECT! I had three different guards made by my dentist before I took a chance & ordered through Sentinel. The three guards from my dentist were all uncomfortable & bulky. A complete waste. I was so discouraged. I chose the 2mm night guard and it is perfect. My headaches and facial pain are gone. I'm very happy! All around great experience!

Will order again!! Thank You!! My experience has been wonderful. So glad i found you guys!

I checked out a few sites before choosing this one because I wasn't sure if I was able to get a good fitting night guard since I don't have the straightest of teeth. I was worried only a dentist could get the right impression. I went for it anyways and it has fit perfect since. No more jaw pain and I'm sleeping better. Sentinel was really easy to work with and I'm very impressed.

Both thumbs up! Terrific job. Saved me a ton. Heed my advice people: Keep these things away from CATS! This is my third one in about 6 months because of my little guy Rupert! Luckily they're affordable!

I clench my teeth. I don't grind but I kept cracking crowns which is just ridiculously expensive. The thought of wearing a mouth guard over my teeth while I sleep just seemed unlikely. I tried the ones from CVS with no luck. I asked for a thin version of the soft guard and it's perfect! Sleeping with it in took some training but if I have to wear one I think I got the best one I could get. Thanks a million guys!

Friendly staff and quality mouthguards. Both thumbs up!

My experience with the Sentinel team has been wonderful. From start to finish I had a million questions that they were great at answering. I was a nervous nancy about taking my own teeth impression but the written instructions and video were easy to follow. I'm glad I went with the hybrid guard. It's very comfortable on my teeth and I have no trouble sleeping at all.

I'm saving up for the full wrap design but for now just to have a quality mouthguard is enough for me. I absolutely love it! Will be back for more!

Fast delivery. Easy impression system, good product and prompt communication. From one business owner to the next, I'm thoroughly impressed. Two thumbs up!

I have pretty extensive damage from grinding my teeth for years. I've cracked three crowns and broken a veneer from teeth grinding. Needless to say, I should have been wearing a night guard a long time ago. Fast forward thousands of dollars later, I found Sentinel through an article online and decided to go for it. No complaints. The guard serves its purpose well. Thanks Sentinel:)
