Soft 1mm nightguard
I have been using sentinel for many years now. Professional quality and very helpful staff. And the polymer is bpa pfhd free. I have paid 300-400 through dental office labs, and not done as well. I just love your company!

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
