Customer ratings & reviews

Great product great price!

This is my third or fourth mouthguard over the last 6 or 7 years. The only issue I’ve had is a little bit of soreness when I first get the mouth guard, until I get used to it.

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.
