These retainers fit great. I ordered 2 lowers for the same price as the upper and lower. My ones' through my orthodontist were cut straight across. These are cut very nicely and fit much better!

I ordered a dual laminate nightguard. The kit came quickly and following the steps was clear and easy. Even with Covid19 shutting things down I received my guard in good time and it fit like a glove. Unfortunately I had bigger issues that appeared with my jaw. I emailed my problems and Alexandra replied promptly but my problem requires a more complex solution that has to be done in person with a dentist. Sentinel refunded my entire purchase price just as they guaranteed when I mailed the guard back. I would definately use their company again if my family needs other products!

Finding the perfect nightguard can be a lot like the Goldilocks story. As a nightguard user, I have gone through many and it really does come down to personal preference and the ability to have a custom made nightguard for such an affordable price is a blessing!

Researched a few companies online before settling on Sentinel. My main grievance with the other night guard labs was that none of them answered the phone. Some didn't even have numbers to call (just emails) and they were slow to respond. Sentinel was prompt and happy to answer my million questions. They made me an exceptional comfortable and STURDY dental guard. Happy customer here! Thanks a ton!

For years I've smoked cigarettes and I finally stopped. I thought I'd never be able to get whiter teeth but this stuff works. It took me about 7 consecutive nights to see a real improvement but what an improvement. Now anytime I need to touch up my teeth I just whiten for a couple of days & that's all it takes. My wife is pleased with the results as well. Thanks a bunch.

MIX FAST! I mixed my putty too slow and the putty hardened before I was ready. I contacted the sentinel team and they sent me new putty. 2nd time around went much better but mix quickly because the putty will harden and you will not be able to get your teeth into it! End product fit great. I've been wearing it nightly and have seen a significant reduction in my jaw pain and morning headaches.

When my dentist said he'd give me a deal on my second night guard I was stil heartbroken at the price. So thankful for the internet. Also, pro tip: I use castile soap to clean my mouthguard. Dr. Bronners on Amazon sells a big bottle of it. Better than the harsh toothpastes and denture cleaning solutions! Mouthguard fits perfectly . A+++

I love my new guard! Thank you!

I have an unusual dental anatomy and feared the dental guard would not fit correctly. These guys are true professionals. They somehow managed to make a great fitting guard for me and I couldn't be more satisfied. I have had dental guards made by other online companies and none of them fit. I did have to take my dental impression twice. The first time, it was rejected. They said they needed a better impression and gave me a redo kit for free. I spoke with a lady on the phone who was very helpful in giving me some tips for a better impression. The guard came within a week 1/2 of sending off the impression. It does take a little bit of time to get used to but stick with it. It will become comfortable after a few days or so.

Love love love! Took a couple of days to break them in but now I'm wearing them all the time. I talk with them in during the day. Totally worth it for me.
