Really helps with my constant clenching. Fits great and not chunky like my old dentist made guard. Super friendly office staff! Thumbs up!

Loved this so much I ordered a backup. Fits beautifully. This is the first time I’ve ever worn a custom made guard and I’ll never go back. Thank you!

I was hesitant because I didn’t know if I could take my own dental mold of my teeth. I messed up the first time but the kit included a backup putty pack. I emailed the company a picture and got an immediate response that the dental mold was good to go. Guard fits well. *****

So, first off, these products are made here in the USA and the company is transparent and helpful about the products they use. I have a gluten allergy and I'm also very cautious about the use of plastics. I contacted several other companies and asked them about the safety of their products. Sentinel was the only company to provide me with detailed information about the materials they use. I feel comfortable ordering from them because of this. I've worn the guard for several weeks now and have no complaints. Very happy with this product and would highly recommend for daytime teeth clenchers like myself.

When my daughter’s night guard finally wore through, I tried Sentinel after reading the reviews. She mostly grinds her teeth during the day so after a conversation with the customer service, we went with the day guard. The process works a lot like how it would be handled at the dentist's office but with fraction of the cost. They send you the impression kit, you send it back to them and within a week or so you receive the guard. The first time we sent the impression, the top wasn’t deep enough so they sent us another kit for her upper teeth. We gave it another go and it worked. The fit is very comfortable for my daughter and so far it seems sturdy. It’s a great alternative way to get your night guard for daytime and I highly recommend purchasing from Sentinel.

I had been looking for something like this for quite a while. I clench my teeth so badly at work but I have to talk and smile during the day and didn't want to wear anything that people can see. I chose the 1mm and it's perfect! Thin and stays in place. Thank you!

I get bad headaches during the day from clenching my teeth. Been wearing the no show day guard for a week now. I wear it at work, at home, at the gym. So far it's an excellent product! I forget I have it in and no one is the wiser! A+++ Thank you! -Chasity Freeman
