Customer ratings & reviews

As a professional fighter I'm always looking for good solid gear that can last through intense training while giving the comfort to focus on what I need to do. The fit is excellent. The guys at Sentinel are great too. Easy company to work with. I've ordered a few guards over the years. Can't beat the fit.

Have been using my 1st order for almost a year and they are great. Quality is the same if not better than the ones I got from the dentist!

Got a different brand the first time I ordered online and the mouth guard was okay. Should have went with this brand to begin with. Noticeable difference in quality and fit. Turn around time was fast too!

This was a replacement retainer for another I had from a dentist which wore out in a year and a half. The Sentinel retainer fits very well, is thinner even than the old one and the price more affordable. Customer service was excellent - the first retainer I received did not fit perfectly so I contacted them via Live Chat and response was timely and helpful. Sentinel recast another retainer and also sent another dental impression kit in case the new one didn't fit. Well, the recast retainer fit just fine so no need to do another impression. When Sentinel says they stand behind their product and want the client to be 100% satisfied, they follow through!

Love that this company lets you choose your own thickness. I have the worst gag reflex and needed a very thin nightguard. I'm pretty sure this is the only online company that offers the thickness choices. Happy customer!

1/2 the price of my dentist and just as good!

I ordered these a month before my wedding. I was worried I wouldn't get them in time but I got them quicker than expected. Results were great! My teeth were nice and white on my wedding day. Thanks so much! Customer for life!

I just received my night guard and it fits perfectly. I am going to order a second one to have on hand because I travel a lot...this way I can keep one at home and one in my luggage. The process was easy and quick, except the return was delayed by USPS. When I talked to my dentist about needing a night guard they quoted almost $700 for one and I will pay under $150 for two. Also a co-worker just ordered one from her dentist for over $800. This is the way to go if you need a night guard and if you have a Health Reimbursement Account you can use that to pay for the guard. I would recommend this to anyone looking for a quality product (same as you get from the dental office) for an affordable price.

Didn't realize I would have to make a mold and send it back in to the company but am excited to see how it works. Kit seriously came within 2 days. Eagerly awaiting the final product to come back. Excellent company to work with!!!

Took less than 4 weeks total from start to finish. I wish it was a bit quicker because I had a fear of my teeth shifting but nothing had changed and the guards arrived and fit perfectly. These are $300 at my dentist so I guess I'm willing to wait a bit to save the money.
