Customer ratings & reviews

I AM VERY PLEASED The comfort of this night guard exceeded my expectations. I use this product from grinding in my sleep and it works well. Stays in place all night. I can even talk with it in easily. Came with a quality storage case and a warranty! Can't beat it!

Super comfortable and easy to wear. I would recommend.

Perfect fit! Thanks! -E.D

Your site was the only one that offered the "choose your thickness" option. I am grateful for this, as I wanted two hard night guards in two different thicknesses. One to wear during the day and one at night. The process wan easy and I received my night guards yesterday. Both fit like a glove and I'm looking forward to ordering more in the future.

Placed my order on June 12th and the process is already complete! Customized night guard arrived in a retainer case & enclosed in a large bubble mailer. Craftsmanship is high quality. Fit is superb. I look forward to getting many years of use. Thank you team!

What a difference it has made in my jaw! I was waking up with horrible jaw pain and headaches. Wearing this guard has been an absolute life saver!! Fast shipping and probably the best night guard ever! I'm team green! Go Sentinel!

Company was kind and cooperative when I messed up my dental cast the first time. Word to the not-so wise, be careful about your time when mixing the putty. I mixed mine for too long and it hardened before I could even sink my teeth. Second time was much easier. Received my Sentinel guard today. Really nice quality. Fits well.

I ordered a dual laminate and a thin hard night guard (for daytime use). Got my two mouth guards and both fit great! You all have been a pleasure to work with. Thank you!!

I can't believe I have been paying $600 a pop all these years for the exact same nightguard as this one. After I lost my last one, I contacted my dentist who wanted to still charge me full price for a replacement. I was hesitant to order from Sentinel because how could it be the exact same thing for so much less? I'm so relieved I went ahead and made the purchase. You all have a customer for life. Thank you.

Easy and inexpensive!! 5 STARS!
