Customer ratings & reviews

I love this night guard. I needed a night guard because I grind my teeth. I was in so much pain every night. I’ve worn a custom one from my dentist & a few different ones that you wear on the bottom teeth but I like this one better. The one from my dentist was too tight. I asked him to adjust it and he did but it was always still too tight.The store bought lower teeth night guards were too loose and they would just end up on my nightstand. This one is perfect. I’ve only had it about a week but it fits great. I have a small mouth and it’s snug on me which is good because it stays on. I don’t think it’s too thick so it doesn’t bother me to wear it. It’s also not extremely thin but I wouldn’t think a thin one would hold up with grinding! It teeth impressions were also easy to make! I made sure to pay attention because I knew the fit could be jeopradized if I did it wrong. Overall, I'm very pleased with my purchase.

Thank goodness we can take more that one dental impression because this is not my thing. ???? After ruining the first two trays, I finally figured out what I needed to do to the 3rd one. I mixed it a lot faster the 3rd time around and it finally worked out for me. After I finally figured it out, I mailed it into the company. Got my night guard back about a week or so after I sent off my impression. I couldn't believe that there is a product on the market to make a custom mouth guard. After I got my braces off, I think my mouth guard was around $400. This was way less expensive and looks really similar. I'm happy with the end result!

These worked great! I needed the heavy duty as I have been a teeth grinder for many years. Took an impression of both my top and bottom teeth but it's only to make sure the bite is correct. I'm so grateful because I have a bad overbite, but they still fit over my teeth perfectly! The guard stays in place while I'm sleeping! I've had a bad run with mouth guards in the past so I've been going off and on without protection for way too long. This is a lifesaver! I'm so happy it fits.

I bought this until I can fitted for an occlusal guard for TMJ. The TMJ guard I will be getting is $1200. Ouch! But I have some dental work coming up and I'm not going to spend that kind of money if my dental anatomy is going to be changing. It took a few tries before I got a good teeth impression. The instructions say not to "bite down" to form it to your teeth. I did bite down the first time and it caused distortion. I retook it and didn't get the teeth submerged enough. Used all the putty but the company sent me a new kit for free. This is a great temporary solution for me. I've only been using it for about a month but so far, I recommend it.

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!

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.

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!
