Great fit

First impression and the fit is great. Happy to be proactive in protecting my teeth.

Your guards are the only ones I've owned that last longer than 8-10 months

I have worn a bite guard for 20+ years, and until I found Sentinel a few years ago, I was literally eating night guards. Mine had to be replaced twice a year at least because my grinding is so bad they just fell apart. My Sentinel guards are 3 mm, and hard, and I have not need a new one more than every two years. The only reason I replaced my last one was because I felt after two years it was probably time. It was still in good shape. AND, they are less than half the cost of what my dentists were charging me. Thank you Sentinel! I'm so glad I found you.

PERFECTION!!!

I had been wearing my beat up retainers for a while I just couldn’t find anyone to replace them for a price that I could afford. I found you guys & they fit perfectly nice & snug, way more durable than the ones I had & they’re just perfect! Let’s just say you guys have a customer for life & I will be purchasing more just to have on hand. Thank you for saving my smile!!!

Best decision for my teeth and sleep!

I stumbled on Sentinel Mouthguards through a review online and immediately went to the website to read more. I had been wearing a guard purchased through my dentist and found it to be hard on my teeth. I was concerned this guard would still grind my lower teeth at night as there was no give. I paid $400 for it and was disappointed. I then purchased a do it yourself kit on Amazon and that guard was bulkier but softer yet not a proper fit and I didn’t know if the plastic material was safe. The Sentinel guard was the best purchase!! The kit is easy to follow for making the mould and when I received my finished mouthguard (I chose a soft version) it looked like my upper teeth and fit perfectly to them. No hard snap in either. It’s comfortable and I don’t worry about any side effects from the material or fit. I can’t sleep without it! Highly highly recommend Sentinel. Very affordable too!

Really happy with it

I initially looked into this one because I read it was less toxic than most - that it was only made from PLA vs really terrible stuff. The mold was an easy step and when I asked to have it adjusted (it was a little tight) it was returned and really surprisingly comfortable. 5 stars in my book and excellent customer service

Great customer service and they helped by providing additional impression material when I was learning how to take a quality impression. Most of all it was a fraction of the cost compared to what my dentist wanted to charge me for a dental nightguard to protect my teeth when i grind them while sleeping.

Custom Dual Laminated Night Guard

Five Stars for Customer Service

Unfortunately, the hard night guard did not work out for me. The first time I received it, it was too tight. Emailed customer service and they sent another impression kit free of charge and sent me another guard. It was still too tight and made my teeth feel pressed together. I worked with customer service again and sent this one back so they could adjust it. It fit better when they returned it but was still giving me the sensation of pressing my front teeth together. I emailed customer service again and they are sending me a dual laminated guard now, since it will have a more forgiving fit. Sentinel really honors their guarantee and have been very kind to work with. They haven’t given me any push back in working to make sure I get a mouth guard that fits. I am really impressed with their customer service more than anything.
