Customer ratings & reviews

High quality and beautifully crafted, the 3mm hard guard exceeded my expectations. I especially like that they don't cut the material straight across. The guard is low profile (it doesn't extend up over the teeth). I find it comfortable, and the teeth impression process was not too difficult to get done, but i can see that an older person may have trouble because you do have to mix the putty fast and work quickly.

Been ordering mouth guards from Sentinel since 2013. They have always put the customer first and their product is great. Consistent, good service. You guys have a customer for life.

This mouth guard is great. I sometimes use it during the day when I feel a headache coming on. I know I clench my teeth during the day too. Then I just make sure to clean it and put it by my bedside for night use. Cleans very nicely and easy to store. It doesn't look cheap. This is a really good price for a high quality mouth guard.

It’s true there really is a learning curve to wearing a strange plastic thing in your mouth at night. However they do get more comfy overtime. Easy to do the putty process. Hopefully it will last a few years.

5 stars!!!

You guys rock! We appreciate you so much. My husband and I are long time customers. We tell everyone about you. Keep up the good work! A+!

I absolutely love it! My mouth feels so much relief and the customer service is spectacular. It is so much better than another company that I had tried previously. The fit is perfect for my mouth and I feel comfortable wearing it.

Been wearing mine for a few weeks and it's been a life changer. My headaches and jaw soreness are gone! I've had many night guards through the dentist. I've paid a lot of money for these things. It's nice to find an affordable option that still has the high quality I need. Thank you!

Not super comfy at first but really nice looking. I love that they are super low profile and the quality is great for the price. I totally recommend these.

Tip from a customer who learned the hard way! Don't bite down into the putty. Keep your mouth relaxed and press the putty filled tray into your teeth evenly. After 3 tries I finally got it right! The sentinel team was gracious and gave me two free kits. Best company ever! My mouth guard fits perfect and my jaw feels so much better. No more popping and clicking!
