Customer ratings & reviews

I must have been born with big cheeks or something because I have bitten the inside of my cheeks for as long as I can remember. Sometimes it would be so bad that it would keep me up at night. I googled how to stop cheek biting and came across Sentinel. I called their customer service and had a few questions about the potential difficulty of taking my teeth impressions. The lady on the phone assured me that it was easy and that they supply extra putty in case I mess up. She was very kind and knowledgeable. Took about 10 days from the time I sent off my teeth impressions to receive my cheek protection guards. They fit perfectly and work perfectly. Happy with the process.

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.

My dentist found some damage on my teeth from grinding. He recommended Sentinel as an affordable option. I checked out the reviews online and they're amazing. I'm grateful for the recommendation. The night guard is slim and fits perfectly to my teeth. It is a quality product.

I recently lost my dental retainer. I only wear a top one so I didn't need a lower one. Customer service said I could either order 2 top guards or get 20% off if I only wanted one. I ordered 2 top guards to be safe. I'm grateful I didn't have to spend $500 at my orthodontist. Exactly as advertised.

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.

So easy to make the mold and fits like a glove!

Due to the pandemic, my teeth grinding went from bad already to worse. I'm currently on my 2nd night guard from Sentinel. Ordered my first one back in 2017 and now in May 2021. This is a great value. The product is high quality and a great bang for your buck. Customer service is always outstanding!

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.
