    Custom Soft Night Guard

    2nd one works excellently

    fit is weird every evening and fine in the morning. I think my teeth shift a bit and I can't blame the nite guard for this.

    Nice

    I love that it's soft so as to cushion & no irritation to sensitive mouth. Highly recommend.

    Don't Pay More...

    My dentist was going to charge me $250 out of pocket for a guard, not including whatever they charged insurance AND it would have taken 3-4 weeks. This was a great solution, an easy process, and a fraction of the cost. Very happy!

    Best I have used

    I have used other mouth guards in the past but these have been the best and the customer service excellent. It took three tries and quite a wait to get them ( due to my mouth shape ) but it was well worth the waiting. Customer service was great in guiding me. I will continue to use Sentinel mouthguards in the future for sure.

    Doesn’t fit

    For many years, I have been ordering my mouth guard from Sentinel and had no issues, 5 or 6. However this time around it doesn’t fit and it doesn’t stay on my teeth. On the service team’s suggestion, they replaced it by removing molar sections on both sides but the issue was the same. May be it was the imprint that I took. Either way it doesn’t fit. Sentinel is sending me a new kit to fix the issue.

    Great little gadget!

    This little gadget first cleans the gunk from my nightguard (ultrasonic cleaner)…it then sterilizes the inner surface afterwards (UV light). I 100% feel this works because there is always a little gunk at the bottom of the container after using the ultrasonic cleaner, before I dump the water. I then dry the inner surfaces with the cloth provided, and expose the inner surface of my night guard to the UV light, letting it sterilize everything. I don’t have to scrub my nighguard with a toothbrush, ever! I used to work in a laboratory and the UV light was used to sterilize all surfaces. This is why I feel this great little gadget is totally worth it!!! Thank you!

    A perfect fit‼️

    These mouth guards have proven to be a wonderful solution for bruxism. Customer service is above & beyond. Wish I had known about Sentinel Mouthguards sooner!
