Customer ratings & reviews

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.

I'm 30 years old and I take care of myself. I feel like I have low stress but for some reason I grind my teeth like crazy! My jaw pain became so severe I couldn't eat hard foods. I couldn't afford the dental office cost so I took to Sentinel and I'm so glad I did. My jaw pain is completely gone. I wear this soft guard during the day and a harder one at night. Definitely eliminates the daily grind!

My new Sentinel guard is perfect! It is so light and comfortable. I would definitely buy again!

They worked with me to get my impression right and didn't charge me for extra kits. I appreciate their commitment to their customers. I had an issue with my first guard and again they worked with me and remade the guard. The second one fit like a glove. They're a small business right now and I hope they don't grow and lose what makes them great.

My night guard fits perfect and is so comfortable! I’m glad I went with the 2mm thickness. Thank You!
