5 stars!! Most comfortable retainers I've ever had!! The main difference between these dental retainers and the ones from my dentist is that they are made better. They trim these so that they don't put pressure on your gums. Makes all the difference. I'll only purchase from Sentinel from now on. Pleasantly surprised!

Being able to choose how thick these are is a plus. Needed two of these. One for MMA and one for weightlifting. I got a thinner one for weight lifting and a 3mm one for MMA. Fits well. Made well. I recommend.

I purchased this because I have an area in my cheek that I couldn't stop biting. I was worried about the time it would take so I did the expedited shipping option. Kit arrived and process was pretty straightforward. Quick turnaround time and great product. It really does work! I did need to wear my guards during the day and night at first but once that area healed up, I quit wearing them all the time. Good to know I have them if and when it happens again. Thank you!

Much less expensive than the dentist yet seems to be the same quality. Headaches and jaw pain have gone away! Easy set up.They provide you with simple instructions. I recommend!

I wear it all day every day! Couldn't be happier with this night guard. I can't stand night guards but this is different. There is no pressure on my teeth. Just stays in place and prevents my teeth from clenching while I'm working. I'm happy with the product and company.

This mouth guard is amazing. I grind my teeth very heavily during both the day and night though I think I'm clenching more during the day. Brought this into my dentist appointment assuming he was going to tell me it was no good and to buy his $800 mouth guard from his office. He looked at it both in and out of my mouth and said it's a "very well made guard." I've tried many store brand mouth guards and bit right through those within months. Sentinel will be my go-to brand from now on.

Love my new night guard! It's soft but durable and cozy. When my dentist told me I was grinding my teeth, the thought of wearing anything night after night in my mouth was just unbearable. I got one made through her at first. It was hard and big and bulky. I hated it! I wouldn't wear it but I knew I should be wearing something. After researching online, I came across Sentinel Mouthguards. I was nervous to take my impression but the customer service rep was very helpful. She walked me through the process. My night guard feels so much better than my previous one. I'll never wear another type. Thank you Sentinel!

Absolutely love this guard. I'm a heavy grinder but I cannot wear a hard guard. The 3mm soft guard works perfectly for me. This is my second one. The last one took about 18 months to wear through. Not bad and so much cheaper than the dentist. 5 stars!!

Went to order these on Amazon and can't find them anymore. Are they only available on your website now? This is my third pair (dog keeps chewing them up). I'm so happy this service exists. So much less expensive than my orthodontist. Keep up the great work and please let me know if you plan to sell on Amazon again?

I needed something that was not going to take up a lot of space in my mouth. The night guard I replaced was big and bulky. Overall, I like and it's exactly what I paid for & wanted. Shipping was fast. Couldn't have asked for anything better. *****
