Customer ratings & reviews

Thank you

The Tongue & Cheek Biting Relief Mouthguards are working flawlessly. Not a single biting episode since the very first night of wear. Took 1 night to get adjusted to the wearing of your guards. I should have purchased your mouthguards a longtime ago. I could have spared myself a lot of misery. Thanks for a superior product. Keep up the good work. 6 stars

Durability Mouth Guard

I've had two mouth guards from Sentinel and they've been fantastic. They're thicker than the mouth guard I had gotten from my dentist which I cracked within two months and cost me twice as much. My first Sentinel durability mouth guard lasted almost two years before my severe bruxism cracked it. My new one is going strong; it’s thick enough to protect my teeth and just as easy to sleep in as a standard mouth guard. And the customer service has been so helpful and courteous every time I've needed help.

Works Great

After just a couple uses, my mouthguard looks brand new and fits better. I tried to brush it, even with hydrogen peroxide, but it never came clean before. Now, it is nice and clean - I use a combination of filtered water and hydrogen peroxide in the cleaner and change it once a week. Super convenient.

Exactly what I needed

As braces are not an option, I needed a little help keeping my front teeth from catching my inner lip while sleeping and causing irritation. This works perfectly! And it is soft and very comfortable and fits very well. I hadn't expected it would work this well for me so I am a very happy customer!

No complaints

It fits, it works, and Sentinal had to resent the imprint package to me twice because I screwed up. I appreciate that.

Fits perfectly. Well done.

Fantastic

This is the second mouthguard I have ordered from Sentinel because their products and customer service are superior. I have ordered from many other companies who make mouthguards including Remi and no one compares to Sentinel. The process is so quick and simple. When I accidentally ordered the wrong type of mouthguard they were so kind and sent me the one I wanted. Other companies, especially Remi are horrible. They send faulty materials for making the mouthguard so it’s impossible to make a good impression and then they NEVER respond when you try to get help. Sentinel is the complete opposite. So grateful for my effective mouthguard from Sentinel.

Like lightweight and it snaps in perfect

Very comfortable
