Customer ratings & reviews

My teeth and jaw were so bad off before I started using the Sentinel guard. I have a 2mm upper. It's a lifesaver! I can't sleep without it now! 5 stars and I'd give 10 if I could!

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.

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!

AFFORDABLE AND PRACTICAL! Nothing fancy, but that was exactly what I was looking for! I hated how terrible my cheap, store bought guard fit. This does the trick and worth the wait!

This worked PERFECTLY. I clench my jaw during the day and at night and have sensitive teeth because of it. I had a $400 mouth guard from my dentist but it was so uncomfortable I couldn't wear it. I chose the 2mm thickness after talking to customer service. It's thin but the quality is still high. I will definitely never be buying guards from my dentist again. This is a wonderful product!

Really gets the job done! This is so fantastic. My teeth and I are thankful!

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 stress of the world was causing me to clench my jaw at night. I had a lot of soreness in my jaw. I chipped a tooth and after a lot of research gave this a try. This product has outstanding value as far as quality vs. cost goes. My dentist wanted to charge me $460 for a night guard. This is the first time I've been pain free in over a year. Thank you Sentinel!

Perfect fit. No need for adjustments. This is a very well made product. Super professional. I will update this post if needed but have been very happy so far!

Ok so heads up this will be a weird review and I am giving this such a high review for a reason despite the fact that I hate wearing a night guard. Period But here is why it gets a perfect review other than price: The night guard fits precisely to my teeth. The low profile makes it not press so tightly onto my teeth. It's literally perfect. Not too tight but snug. The thing is, if you ARE a night guard wearer and have gotten lucky enough to have found a perfect guard, congratulations. I was not so lucky until now. This guard beats all other guards I have tried by a metric mile. Now, this should be a perfect review but I'm deducting a small percentage of a point for a scratch on my retainer case. 9.75 out of 10 for matching me with the perfect night guard. My teeth grinding pain is gone. That is what I bought it for so mission accomplished. Thank you!
