Customer ratings & reviews

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

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!

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.

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!

My night guard fits perfectly & is quality Would not hesitate to use this company again

Excellent all around! 5 stars!

Very happy with the level of customer service and the high quality product. If you're on the fence about it, it's definitely worth the money.

This is my second purchase from this company courtesy of my dog chewing the last one. Before I found Sentinel, I had spent $500 on the same thing from the dentist. Making one impression takes about 5 minutes from start to finish. You do have to take a second impression of your lower teeth too (also takes 5 min.) so allow about 20 minutes total to familiarize yourself with the instructions, etc. Make sure you mix the two different color putties together quickly until they are one color, then you put it in the tray and press your teeth and you're done! Mail it off and you have a mouth guard back in about a week. Very easy, and well worth the money.
