    Happy with my Ultrasonic Cleaner

    Easy to use and definitely helps clean my night guard after use. Very happy with the product.

    Very comfortable

    This soft 3mm Night Guard is surprisingly super comfortable. Even after I wake up mid-nights still wear it during the time it takes returning to sleep.

    Helps with teeth clenching & grinding

    I've been using Sentinel night guards for a few years. As it turns out, I clench & maybe grind my teeth while I sleep. It became bad enough that a few teeth were actually becoming loose. The night guard has remedied that situation & the dual laminated night guard seems to work well for me.

    Impressive!

    I couldn’t ask for a better fit. No adjustments necessary! Excellent workmanship.

    Straight and Safe

    Love these guards! I rest (literally, while I’m sleeping) with the peace of mind my teeth are staying straight after braces and safe from the annoying clenching I do at night. Love it!

    Excellent Customer Service!!

    This is my second purchase from this company. I needed some adjustments to my Guard and it was so easy and such a pleasure to do. I will only recommend Sentinel to anyone, and only buy from them. Fantastic Company

    Great night guard for severe TMJ

    I wear my guard at night and when doing strenuous work. It helps a great deal with my clenching. I will still need surgery but it is helping.

    Great product great price!

    This is my third or fourth mouthguard over the last 6 or 7 years. The only issue I’ve had is a little bit of soreness when I first get the mouth guard, until I get used to it.
