No more cheek biting

Since using these I no longer have cheek biting sores like I did with my other upper dental splint. The Mouthguards are so comfortable too - sometimes I forget I’m wearing. Money well spent! Thank you sentinel! I wish there was somewhere in Australia that did something like these.

Great service

I appreciate that Sentinel worked with me to ensure a comfortable fitting guard after the first one wasn't quite right. I often forget it's there in the morning!

Soft and comfortable

This new material is soft and comfortable yet still provides plenty of protection from grinding. I think this new style is great!

I absolutely love this mouthguard!!!

Sentinel mouthguards are great, the mouthguard itself is exactly what I needed, and wanted. It can't be seen, and when I am wearing it there is no slur of speech, or anything like that. The customer service is some of the best I have experienced. They are professional, but courteous. I messed up my first molding kit, they sent me another without question. My mouthguard broke and sentinel mouthguards replaced it with a stronger version suited to my needs. I highly suggest this company and this product..

Custom Soft Night Guard

Mouth guard

Good product

Great fit!

This is the best fitting night guard I've ever had. I think it's a great price for the top quality & fit. The customer service is wonderful. I had questions, and they were all promptly fully answered. I found the impression process easy. The instructions & video were simple to follow.

Perfect fit!

Excellent quality retainer at a much lower price than my dentist.

3rd times the charm

I first tried the a boil and bite night guard and then a disposable partial night guard. The boil and bite was too big in my mouth and caused jaw soreness over time. The partial caused minor tooth aches as only a couple teeth were covered and took all of the grinding pressure. The sentinel night guard was a completely different. It was way more comfortable and I did not have concerns of it shifting my teeth or hurting my jaw. It did take me 3 attempts to get a good mold but customer service was quick to review pictures to identify problems before I shipped my mold. Watch the videos of how to do it properly and you should be ok. I am confident I would not have molding issues in the future now that I understand the proper way to form the mold.

Excellent Fit, Quality, and Customer Service

I absolutely love this night guard! I had a small issue with the fit of my first one, but Sentinel immediately sent me a replacement that was perfect. The customer service was great and the product itself is excellent. This is actually my 4th night guard, and I’ve usually gotten them from the dentist for $200+and honestly, those weren’t even as good as this one. I paid a fraction of the price and received the best-quality night guard I’ve ever had. Highly recommend!
