Customer ratings & reviews

This night guard is awesome! My teeth fit easily and comfortably inside the guard. I waited to review to see how long it would last. Usually by now the my old night guards that I've gotten in the past from my dentist start to crack or wear down but this one is still holding strong! I do take very good care of it and keep it in its case by my night stand. I clean mine once every week with Efferdent denture cleaning solution but I think that is a personal preference. I don't want it to yellow!

It works! Biting my cheek is a real bummer. This product helps cut the pain for sure. Good for managing pain.

Does the job The guards are easy to wear and the process was easy and quick. It definitely stopped the pain from my tongue biting issue.

I've had these guards for over 3 years and I'm just now ordering another set. Thank you for delivering an excellent product!

PERFECT FOR SENSITIVE TEETH! I don't write reviews very often but my hunt for a teeth whitening product that doesn't make my teeth feel like all the nerve endings are firing at the same time has ended! I don't leave the gel on very long because I have super sensitive teeth but it still has whitened my teeth very well. I still have plenty of gel left over to re-whiten when they start to yellow again too. The professional quality trays fit snug on my teeth. I'm very pleased with the whole experience.

THE MOST COMFORTABLE! Initially, the upper retainer fit great but my lower was off. Contacted customer service and was promptly sent a new kit. They remade my lower retainer quickly and it fits perfect! I saved a lot of money and the quality is excellent.

This is the best mouth guard I've found for daytime use. I clench my teeth horribly during the day. I use this while I'm at the gym and in the office. This is a great article they sent me about how to take care of it and keep it from turning yellow. I've had many many night guards before and if you don't take care of them properly they will turn a nasty yellow! Thank you Sentinel team. You have a customer for life!
