Customer ratings & reviews

Very easy process. I went with the thickest one because my bruxism is severe. I wear this nightly with no issues. Satisfied customer!

Thank you for making a night guard for my bottom teeth It's great that I can choose my own thickness and if I want one for the top or bottom jaw. I prefer a bottom guard because I can tolerate it better in my mouth. Very pleased with my purchase! Will be ordering again in the future for sure!

Sentinel! Thanks for keeping my teeth protected! I've been a customer now for 4 years and am a bad grinder. You stood by your warranty when I ground through my first night guard after 16 months. Just ordered another. Can't thank you guys enough for making custom night guards affordable.

I love this mouth guard. It is THE most comfortable one I've ever had!! Thank you!

Sentinel Mouthguards was very accommodating when I realized I needed to switch my order to a male kit at the last minute. Got the correct kit & impression process was easy.

I am very happy with my night guard and I recommend this. The customer service is exceptional!

I recently started biting my tongue and inside of my cheeks during sleep. Frustrated, I made an appointment with my dentist who said I needed both upper and lower bite guards to prevent any further damage. His quote was $700 for the set. I couldn't pay his price and was so relieved to find this website. I got both for around $160 using the "big spender" discount code. They fit great! I chose the 1mm thin ones and they're not bulky at all. Glad you guys exist for poor folks like me! :D I'll recommend you to everyone I know!

These are fantastic, well-made, shock absorbent night guards. After multiple uses now, my headaches and jaw pain are non existent. I just don't seem to have any issues anymore! Thanks for the excellent service you provide.

I had a small issue with the initial fit of my night guard. I contacted Sentinel and they promptly sent me a replacement. Fits extremely well and couldn't be happier with the professional and timely customer service!

As I get older I've realized the importance of my teeth. I feel so much better knowing that I'm taking the right measures to make sure they last as long as they possibly can. I've tried many mouth guard types and not only is the Sentinel guard affordable, it is comfortable. I chose the 2mm Dual Laminate and am very satisfied. Thank you@ Sue & team
