Customer ratings & reviews

I've had guards from other companies and not one of them have taken the time to shape the guards so beautifully and it matters! They all were cut straight across but these fit soo much better. I don't normally leave reviews but had to jump on and tell you how pleased I am with the fit and quality. They're thick enough to protect my tongue but not too thick. They really are made for me only. Worth every penny!

I went through several online companies before finding yours. I had to return every single one of them for various reasons. Hands down best fitting guard I've ever worn. You guys are exceptional and have my business as long as I'm grinding my teeth! -Thomas

I couldn't be happier with this product. Beautifully made and high quality. Super convenient service. I HIGHLY recommend.

Took the quiz to find out which night guard I should get and it said a hard guard. I was skeptical that the hard one wouldn't feel comfortable. First few nights took some getting used to but now I love it. The whole process was smooth, shipping was fast and easy and the night guard fits like a glove. Here's a tip: When you take your dental impression, make sure your teeth are centered in the tray and sink your teeth into the putty all the way while holding still. Don't move around. After 2 minutes or so, the putty should be hard and you can remove the tray. Make sure your impression looks correct before sending it in or they'll have to send you a new kit. I sent in a picture of my impression and they were quick to respond. I hope this review helps someone!

Just placed an order for a second one to have as a backup. The fit is perfect! Thank you~

When I couldn't get my dental impressions correct I became unsure that this product was right for me. I was about to give up but your customer service is outstanding. The girl on the phone told me she had worked in a dental office for almost 20 years and she walked me through taking my own dental impression. Once I understood it, I took two great dental impressions. I sent photos of them to her and she immediately responded back with an A-Okay. Sent them in and received my two perfectly fitting guards. I've been wearing them consistently with much success. Thank you Sentinel. You are a dream to work with.

I've ordered from various vendors online and Sentinel is by far the best. My mouth guard fits like a glove. I sleep with it every night. I recommend you guys over and over. Thank you!

Great feeling mouth guard! I've had the boil types my whole life and finally treated myself to a custom mouth guard. I'm impressed by how nice these are. I definitely recommend!

After I lost my dental retainers I was surprised at how quickly my teeth started to shift. I decided just to get a less expensive replacement set and wear them consistently this time. I went to my orthodontist and was quoted $550 to replace them. No thanks. I found Sentinel Mouthguards online. Took my own dental impressions and a week later, I was mailed a perfect set of upper and lower retainers. $350 LESS THAN MY DENTIST. Thank you for this affordable option.

I was skeptical about this product but the price point was good. The putty kit came in the mail quickly. I took my impression and sent it off. The instructions were very easy and they even include an extra set of putty in case it is needed. They give you the option to send a photo of your impression to see if it's okay and they responded quickly. I chose the thicker one and it is exactly what I hoped for.It's sort of flexible not too thick yet protective. Customer service was superb and I'm super happy!
