Why was this so hard to find??? I searched everywhere on the internet to find something to help my tongue heal and all I could find was mouthwash and orajel. That stuff doesn't help if you just keep biting and reopening the wound. This is the only product that actually makes sense and works. Yes, the dental impression process takes up some time because you have to take your impressions and send them back but it was worth the wait. I'm done focusing on my tongue pain from now on. I am damage free! Highly recommend this service A++++

Loved this so much I ordered a backup. Fits beautifully. This is the first time I’ve ever worn a custom made guard and I’ll never go back. Thank you!

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!

It was super easy to mold to my mouth. I read the directions and practiced with the empty tray before I begin (called customer service and that was a tip they had). The guard itself fit snug the first night but not uncomfortable. I was able to sleep no problem. I woke up with no jaw pain or headache. The relief literally came after one night of use. I've now worn it several times and it seems to be forming even better to my mouth. My dentist told me to purchase one from Sentinel because they're the exact same thing his office would offer but cheaper. Highly, highly recommend this product!

This is my 2nd set of retainers from Sentinel. First set I got through Amazon. Communication is better when you buy directly from the Sentinel website. I understand after speaking with the customer service that they;re a third party seller on Amazon which means that you're better off contacting them directly than going through the Amazon contact. They kept my teeth impressions in their file database and were able to make my 2nd set at a 20% discount. They fit just like the first. I'm very satisfied and will let others know about this great company.

I was hesitant because I didn’t know if I could take my own dental mold of my teeth. I messed up the first time but the kit included a backup putty pack. I emailed the company a picture and got an immediate response that the dental mold was good to go. Guard fits well. *****

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 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.

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.

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.
