Customer ratings & reviews

After one year of use I noticed the dual lamination separating on my guard. Contacted Sentinel and they allowed me to simply upload a picture (proof of dual lamination separating) and sent me a replacement free of charge. Zero hassle. Wonderful customer service. Also, the night guard has helped me tremendously with my teeth grinding pain. I continue to recommend!!

What a delight to find a company that doesn't want to take every dollar you have. These guys are not solely about profit. They give a damn and it's obvious. Huge thank you to you all. Thank you for making this affordable to the people who don't have deep pockets. Love my nighttime guard. Will recommend this to everyone I know. *****

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!

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

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 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.
