Do you find yourself waking up with a sore jaw or pounding headache, wondering why your nights aren’t as restful as they should be? You might be one of the millions who suffer from nocturnal bruxism – the unconscious habit of grinding or clenching your teeth during sleep. But fret not, because relief is within reach.
Custom Comfort, Unmatched Protection
Clenching or grinding your teeth can lead to a range of discomforts, including headaches, jaw pain, and increased teeth sensitivity. Moreover, this habit often results in the gradual deterioration of teeth, leading to wear, cracks, chips, and even breakage.
Made with the safest, durable materials available, our hard night guard provides maximum protection against teeth grinding and clenching, the #1 cause of dental pain and discomfort.

Took the quiz to find out which night guard I should get and it said a hard guard. I was skeptical that the hard one wouldn’t feel comfortable. First few nights took some getting used to but now I love it. The whole process was smooth, shipping was fast and easy and the night guard fits like a glove.
Here’s a tip: When you take your dental impression, make sure your teeth are centered in the tray and sink your teeth into the putty all the way while holding still. Don’t move around. After 2 minutes or so, the putty should be hard and you can remove the tray. Make sure your impression looks correct before sending it in or they’ll have to send you a new kit. I sent in a picture of my impression and they were quick to respond. I hope this review helps someone!

This is the best! I’ve tried many guards over many years of suffering from TMJ, and none worked or were comfortable to wear.
This guard is extremely comfortable and really does help with relieving my jaw pain and protecting the teeth from grinding.
Customer service team is very nice and fast.
Excellent all around experience!

I 100% recommend this dental night guard delivery service. They remove all of the excess plastic for a slim fit. Not at all bulky in the mouth and crafted with care. Thank you Sentinel team!
David Silver
My teeth and jaw were so bad off before I started using the Sentinel guard. I have a 2mm upper. It’s a lifesaver! I can’t sleep without it now! 5 stars and I’d give 10 if I could!

This is my 2nd Sentinel night guard and I will never buy from my dentist again. He charged me $550 every time I went in for a new one and they never lasted more than a year. I will be a long time customer and will continue to recommend Sentinel Mouthguards.
Laura Mason
Didn’t work out for me. I found out I needed extensive dental work after I ordered. Contacted the company and told them my situation. They issued my refund immediately. Suzanne is the sweetest! Thank you for making this easy for me and once I have all of my work completed I will definitely be back!

AFFORDABLE AND PRACTICAL!
Nothing fancy, but that was exactly what I was looking for! I hated how terrible my cheap, store bought guard fit. This does the trick and worth the wait!
Misty Larson
This worked PERFECTLY. I clench my jaw during the day and at night and have sensitive teeth because of it. I had a $400 mouth guard from my dentist but it was so uncomfortable I couldn’t wear it. I chose the 2mm thickness after talking to customer service. It’s thin but the quality is still high. I will definitely never be buying guards from my dentist again. This is a wonderful product!
Jeffrey Hutchcroft
I am sorry to say that the first go around was not a good fit. The lower part of the front teeth on the backside (tongue side) stuck out and cut into my tongue. I sent it back and they were able to smooth it out. Fits better now.
Steve Butler
Really gets the job done! This is so fantastic. My teeth and I are thankful!
J. Dailey
I HIGHLY recommend this bite guard! I found this company, read all the reviews and ordered. Took the guard to my hygienist and she was impressed! I’m a customer for life. Considering ordering a second as a backup!

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!
