Works! I use this all the time. It works very well to prevent me from creating sores on my tongue. It tackles the problem. GOOD STUFF!

Perfect fit! I purchased my first night guard kit from Sentinel a couple of years ago. After 2 years, it had loosened up on me so it was time to purchase another. Consistently good! The second one is just like the first. This is a very well made product and much less expensive than the dentist. Highly recommend!

The stress of the world was causing me to clench my jaw at night. I had a lot of soreness in my jaw. I chipped a tooth and after a lot of research gave this a try. This product has outstanding value as far as quality vs. cost goes. My dentist wanted to charge me $460 for a night guard. This is the first time I've been pain free in over a year. Thank you Sentinel!

Where has this been my whole life?? I can;t believe I was paying dental office prices. I have been a victim of the dental office scam for many years. I'm an older woman and have been grinding my teeth since my 30's. A friend told me about Sentinel Mouthguards and I decided to give them a try. Boy, am I glad I did! I know I'll wear through this one eventually but at hundreds of dollars less than the dentist I'll take it! Really well made, great fitting night guard.

You can't go wrong with this!! This teeth whitening system is the real deal. I've been using other types of whitening for years and much of it is expensive junk. I whiten my teeth about every 6 months and this is perfect. The trays fit like a glove. It took about 5 days to see optimal results for me using the zoom gel nightly for a couple of hours. Plenty of gel left over for future whitening! 5 stars!!

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.
