Customer ratings & reviews

Best decision for my teeth and sleep!

I stumbled on Sentinel Mouthguards through a review online and immediately went to the website to read more. I had been wearing a guard purchased through my dentist and found it to be hard on my teeth. I was concerned this guard would still grind my lower teeth at night as there was no give. I paid $400 for it and was disappointed. I then purchased a do it yourself kit on Amazon and that guard was bulkier but softer yet not a proper fit and I didn’t know if the plastic material was safe. The Sentinel guard was the best purchase!! The kit is easy to follow for making the mould and when I received my finished mouthguard (I chose a soft version) it looked like my upper teeth and fit perfectly to them. No hard snap in either. It’s comfortable and I don’t worry about any side effects from the material or fit. I can’t sleep without it! Highly highly recommend Sentinel. Very affordable too!

Really happy with it

I initially looked into this one because I read it was less toxic than most - that it was only made from PLA vs really terrible stuff. The mold was an easy step and when I asked to have it adjusted (it was a little tight) it was returned and really surprisingly comfortable. 5 stars in my book and excellent customer service

Soft 1mm nightguard

I have been using sentinel for many years now. Professional quality and very helpful staff. And the polymer is bpa pfhd free. I have paid 300-400 through dental office labs, and not done as well. I just love your company!

Very comfortable

This soft 3mm Night Guard is surprisingly super comfortable. Even after I wake up mid-nights still wear it during the time it takes returning to sleep.

Impressive!

I couldn’t ask for a better fit. No adjustments necessary! Excellent workmanship.

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!

Custom Soft Night Guard

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.

Fits and works well

I am very happy with my purchase; fits and works well.
