    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!

  • Barry Rosenthal

    I need it as a lower mouthguard to protect from biting my lip during sleep. I tried a over-the-counter solution which was worthless. Found sentinel on the Internet. Was impressed with a customer service representative, Ashley, who took me through the process and inspired confidence in the company. After receiving the mouthguard, I wanted a slightly deeper impression. Spoke with Ashley again and she arranged to have a new guard shipped with no questions asked and no additional cost. The new guard fits perfectly. I would recommend this company without reservation. Thanks Ashley!

  • CJ Howard

    Love the free shipping and these are the best prices on the internet. I’ve been through other companies and you guys ROCK!

  • Phil Williams

    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!

  • Vadim

    Sentinel is really great! The process was easy, the shipping was really quick. Upon receiving my guard, I used it for two nights and it was slightly uncomfortable in one area of my mouth. I realized it was because I probably didn’t do the imprint process correctly. I contacted Sentinel, they adjusted the guard and sent me a brand new one. This one is perfectly comfortable and allows me to sleep well at night. No more grinding my teeth and I feel healthier already. Thank you to the team at Sentinel for hooking if up!

  • Johann Haynes

    Love these night guards and the people that work there! So friendly and helpful. I have been a customer for 2 years. Always a great experience. Thank you to you all!

  • Patricia Welch

    Love this brand!

    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.

    I rarely leave reviews or contact companies but I felt compelled to reach out and give my thanks. I’m on my 3rd nightguard from your company and I couldn’t be happier. My dentist had been telling me for years that I was grinding and needed a nightguard. Like thousands of other Americans I promptly ignored him until I chipped a tiny bit off a molar due to grinding and realized I needed to get serious about this. I balked at the 500$ price my dentist wanted. I tried a store bought night guard which I carefully molded with boiling water per the instructions and then promptly threw in the trash after gagging on it all night. Then I found you guys and for a fraction of the dentist’s price I received a custom molded night guard. The process was easy, the fit was great and now I can’t sleep without the night-guard in…I feel naked without it. My morning headaches and jaw pain are nearly gone and I couldn’t be happier. Keep on keeping on!

    Just wanted to say how IMPRESSED I am with the lower 2mm nightguard received. Over the years the price of night guards at the dentist office have been $400-$500 and my most recent quote was $798! The finished results at these facilities seemed less custom (even though an impression was taken). In addition, the appliances would require dremel-type grinding by the dentist on the actual appliance so that it would fit better in my mouth – I never expected that a nightguard from a mail-order could FIT LIKE A GLOVE, require no adjustments and feel so comfortable. I can even talk better with it in when compared to prior guards on my lower teeth.
    I do notice that after a week of use I have acquired a few minor rough spots on the guard from my obvious night grinding, so I hope that I have enough thickness, but that is not a complaint in the least. just a hope that I have the thickness is enough for me. Seems like there is always an option to go up in thickness if ever needed.

    A big THANK YOU for being an affordable and reliable resource in a time when dental and healthcare costs are soaring – I APPRECIATE YOU!

    Insurance wouldn’t cover my nightguard through my dentist. Read an article online and found Sentinel through the article. So happy I did! I paid a fraction of what my dentist wanted to charge me. Happy customer!

    A++++ fast shipping. Excellent correspondence & solid product. Thumbs up!!

  • Kerry

    I’m on my third nightguard right now and I could never go back! The nightguard fits perfectly and it is so comfortable. I can completely tell the difference when I don’t wear it. I absolutely love my nightguard! The service of Sentinel is great too! I had a crack in my guard, and they sent me one for free! I would highly recommend this! The only downside is that mine has calcium build up and has yellowed. I’d like to know how to avoid that.
