Customer ratings & reviews

So, first off, these products are made here in the USA and the company is transparent and helpful about the products they use. I have a gluten allergy and I'm also very cautious about the use of plastics. I contacted several other companies and asked them about the safety of their products. Sentinel was the only company to provide me with detailed information about the materials they use. I feel comfortable ordering from them because of this. I've worn the guard for several weeks now and have no complaints. Very happy with this product and would highly recommend for daytime teeth clenchers like myself.

Can’t believe I’m writing a product review for a mouth guard but it’s that good. This is the most comfortable mouth guard I’ve ever worn. I'm impressed by this brand. Responsive, quick and high quality!

LOVE! You must buy! Honestly so great. Fits perfect and good quality for the price.

This company has the patience of a saint because I was horrible at getting my impression right. After 3 different attempts I finally got a good impression. I felt so bad asking for another kit but the customer service was outstanding. The guard came and fit well. It did start to have lamination separation after about a month but I called and they sent me a replacement free of charge. I did not have to retake my impression (thank god). They keep them on file for 12 months. The 2nd guard is doing much better. Love the service! Will order again in the future.

Makes my tongue impossible to get caught between my teeth! I was having the worst pain because I could not stop biting my tongue in this one spot. I tried everything! Rinsing my mouth with saltwater, cold compresses, IB profen. It helps with the pain but doesn't actually heal the tongue. These teeth guards are like wearing gloves over your teeth. It's genius really! It makes it to where my tongue is no longer a victim of my chompers! My tongue has healed. The pain has stopped and I am forever indebted to Sentinel Mouthguards for the help. Thank you!!

This was better thank I expected. I admit I was a little frustrated with the putty impression process. I was so nervous to take my teeth impression and of course I didn't do it correctly the first time. I finally settled down and got a nice impression of my teeth. It was easier than I thought it would be. The Sentinel lab crew took care to make my guard fit perfectly from the impressions I sent. I'm happy with the final product and will reorder again when the time comes.

Same exact thing at the front counter of my dental office. Saved several hundred dollars and it works beautifully! I actually had to take two dental impressions because you have to get your teeth all the way in. But there was an extra set of putty for a retry. Nailed it the 2nd time. Beautiful fit. Thank you Sentinel team. -Julie

Replacement for an old one I lost or grew legs! This company is consistently awesome. I ordered years ago. Loved my last guard and was a bit worried that things may have changed over the years and the quality might not be the same. But like a good wine, these guys seem to get better with age. Thank you again Sentinel! Cheers!

Thank you Sentinel! Affordable prices, great fit and great customer service. My husband and I thank ya much!

Cheapest place to buy affordable night guards. I buy these because I like to wear both upper and lower guards at night. I don't bite my tongue. I grind my teeth but this is a better deal than buying 2 night guards. Would recommend.
