CJ H. Love the free shipping and these are the best prices on the internet. I’ve been through other companies and you guys ROCK!
Darren Brock This team really does go to great lengths to meet customer satisfaction. I messed up my first dental impression and was quickly shipped another for free. Then wanted to change types after I received my soft night guard. They upgraded me and I just had to pay the difference in price. Way more flexible than my money hungry dentist! Great customer service.
Kenneth H. I have pretty extensive damage from grinding my teeth for years. I’ve cracked three crowns and broken a veneer from teeth grinding. Needless to say, I should have been wearing a night guard a long time ago. Fast forward thousands of dollars later, I found Sentinel through an article online and decided to go for it. No complaints. The guard serves its purpose well. Thanks Sentinel:)"
Liz S. This is the best nightguard I have ever owned–better than those I paid $500+ for at the dentist’s. It’s thinner than I am used to which initially concerned me, but the material is extremely strong and durable, so the thinness ends up being a positive because it makes the nightguard less obtrusive and more comfortable.
Ronnie C. I never write these things because I never really care to, but Sentinel really hooked me up. They were really nice on the phone and helped me through the whole process of picking the right guard, shipping, taking my own impression etc. I chose the 2mm because I wanted strength but wanted to keep it thin in my mouth since I’m a light sleeper. This company is very professional, thanks for everything.
Janice I LOVE Sentinel mouth guards! I’ve been ordering from this company for at least 5-6 years. Always quality products, wonderful service, and especially unbelievably great prices! Don’t pay the dentists’ high prices – buy from Sentinel and save money for the exact same thing your dentist makes – at a fraction of the cost!
Jay G. The fitting process was quick and easy and didn’t take long for the custom night guard to arrive (approximately 3 weeks from start to finish). Upon first wear, I was in shock at the positive difference! My first night went smoother and I felt like I got better sleep & zero soreness upon waking. This company will even keep your teeth impression on file for future orders which is a major plus. Thank you Sentinel!
Amanda F. My daughter got a custom bite guard from a dentist before. He took a mold of her teeth just like this. As far as I can tell, the only difference was that it cost more to get the bite guard from the doctor. This product is working great. Prompt, hassle- free delivery.
Bree Hands down, the best night guard out there. I’ve used so so many.. I notice a difference in my teeth/jaw if I miss even one day. I have contacted the company with inquiries, and the customer service reps have always gotten back to me with great response.
Patricia W. This is the only night guard that really works for me! will never go back to other companies. I discovered this company when I visited a wonderful healing center that was treating my TMJ with cold laser therapy. The doctor highly recommended this company and I’m grateful. Sentinel is #1 in my list.
Phil W. I bought this night guard for my son who grinds his teeth. We unsuccessfully attempted the first mold but Sentinel sent another kit out right away. So happy I could get this mouthguard at an affordable price. My dentist wanted to charge a small fortune! Thanks Ashley & the rest of the staff. You guys are great!
