Custom Soft Night Guard


Protect Your Teeth From the Grind

We understand the short and long term effects of teeth grinding and clenching (bruxism). Teeth wear, cracks, chips and sensitivity don’t just happen overnight but once it begins, costly dental repair is needed. That’s why we’ve designed a night guard that’s both effective and comfortable. Our Soft Custom-Fit Night Guard is made to fit your teeth like a glove, providing a secure fit that you’ll look forward to sleeping with. It’s so comfortable, you’ll forget you’re wearing it!

Saving your teeth and your pocketbook

Ask any dentist- there is simply nothing better to eat, laugh, talk and chew with than natural teeth. With Sentinel Mouthguards, your teeth are comfortably protected and your tooth structure stays preserved.

Your soft night guard won’t interfere with your speech or breathing, and it’s easy to clean and maintain. Plus, it’s free of BPA and other harmful chemicals so you can be sure you’re using the safest product available.

Product Reviews

  • Susan K.

    Quality is great!

  • Holly Robey

    Great product. Knowledgeable staff & great customer service. Terrific job!

  • 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. *****

  • Iris Wilkerson NV.

    Got the first one and it felt a little loose on one side of my mouth. Contacted Sentinel team, they told me that it was probably from the initial dental impression. Sent a new kit to me and the fit is flawless. My advice: Pay close attention when you take your teeth impression. If you feel like you messed it up I’d go ahead and contact them. They’ll send a new kit for free. Overall, I give 5 stars. Customer service was on point.

  • Lauren V.

    Bought this for my boyfriend. My boyfriend loves that it is fitted, it is sturdy enough to hold its own shape but not stiff and uncomfortable.

  • Angela Davis

    Great value, low price. Works great, and looks nice.
    This is my second night guard I’ve bought from this company (first on on Amazon). These are made very well, and last quite a long time. First one I bought in 2017. I have been avoiding going to the dentist since COVID19 hit so it is nice that this option exists for us.

  • Amanda Fox

    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.

  • Collette Hudson

    Solid product! 5 stars! Highly recommend!

  • Jayg

    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!

  • James Manning

    My review is consistent with all of these other reviews! Very easy process with clear instructions. Kudos to these guys for saving me so much money!

  • Jenny L.

    Totally worth it! service is top-notch and the fit is spectacular!
