Dental night guard that fits great!

They are the absolute best. I have been receiving dental night guards from Sentinel for the past 10 years. All of the staff are consistent professionals and the best in their field. I can't recommend them enough!

As always, Sentinel Mouthguards has knocked it out of the park yet again. Always great service, quick turnaround time and the fit of my night guard is impeccable. Their work is excellent. I greatly appreciate the attention to detail and the friendly experience.

The customer service of this company is wonderful. They're a small, family owned business and I love that everything is made right here in the USA! I have a gluten allergy and learned that my dentist was using a Chinese lab to make his night guards and couldn't verify the materials in it! I was able to order a gluten free mouth guard from Sentinel that fits perfectly and I couldn't be happier! Excellent product and service!!

I just got my Sentinel guard in yesterday and as I'm sure many others are, I was skeptical to order online. I'm happy to report the impression process was much easier than I thought it would be and the guard is the most comfortable one I've ever had! Looking forward to wearing it at work. Hopefully these daily headaches will stop once and for all!

BUY THIS MOUTH GUARD WITHOUT ANY HESITATION! I did a LOT of research before choosing Sentinel. One thing I found that they offer is the 1 year warranty. I emailed to verify this and if my night guard cracks or wears through within 1 year, they will replace it up to 3 times! That's a big plus for me because I'm a pretty heavy teeth grinder. The guard fits flawlessly. Service was quick and top notch! Teeth impression kit was easy and straight forward and they were patient in answering my many questions. I feel like I did the research for you guys. You will not regret choosing this company to make your custom mouth guard!

Impressed! Very good quality and the fit is exceptional. After many expensive teeth repairs, I have learned my lesson! Wear your night guard! This is the best guard in terms of fit and quality I have every had. This is the company I recommend buying from.

I would not use any other company but Sentinel! Not only are their products high quality and fit like a glove but they're fast and have great communication/customer service. I'm a Sentinel fan for life! Thank you!

Being able to use my FSA card made the an easy buying decision. The molding process did make me a little nervous but it's explained very well in the written instructions and video. They gave me an extra set of putty too in case I needed a reattempt. I sent them a picture of my impression and received a reply very quickly. Excellent guard and excellent service. I will not hesitate to order another guard from Sentinel.

All the other bleaching trays I've tried have made my teeth hurt terribly. I love that the gel is for sensitive teeth. I reached my optimal color on day 5 with no sensitivity. I have plenty of gel leftover to re-whiten when my teeth start to color again. Happy with the service and product *****
