Durability Guard is significantly stronger

This one is much tougher than the regular guard—I went through two of the regular ones, which both ended up snapping in my hands when I was drying them. This durability one is much stronger. It has gotten a bit scratched up by my molars but is still solid. Knowing what I know now, I would have started using mouth guards earlier and would have started with this one!

Comfortable and Effective

The Sentinel mouth guard is comfortable and prevents me from grinding my teeth at night. I have used them for about 10 years now and am on my third one.

Great product

Durability Mouth Guard for Severe Teeth Grinding & Clenching

I was referred by a friend who praised Sentinel's mouth guards and customer service. I live in Wisconsin and was worried about the mail service being dependable and timely. To my amazement, the entire process was smooth and fast. I am very impressed with the exceptional quality of my night guard and the timeliness of the transaction. I can't express how grateful I am for this service. Incredible!

Fast service, high quality and the fit is fantastic!

10/10 recommend! Custom fit to my teeth and the process was straightforward/fast.

Getting started was a breeze! I received my impression kit in the mail, followed the instructions, mixed the mold compounds, and took impressions of both my upper and lower teeth. Then, I just popped it into the pre-paid mailer and sent it back. Within about a week, I had the finished product in hand. I must say, the service was exceptional, and the product exceeded my expectations. It's not only high-quality but also incredibly comfortable. And the best part? It does the job perfectly. Plus, it's a much more affordable option compared to shelling out $500-600 at the dentist for a similar fitting. Highly recommended!

PERFECT FIT!! This is a close to dentist quality as your going to get online. I have gone through several companies claiming to make quality products but Sentinel is the only one I've found that compares to my dentist made guard that I had for years. I would strongly recommend this product and company.
