Product Reviews

    Where has this been my whole life??

    I can;t believe I was paying dental office prices. I have been a victim of the dental office scam for many years. I’m an older woman and have been grinding my teeth since my 30’s. A friend told me about Sentinel Mouthguards and I decided to give them a try. Boy, am I glad I did! I know I’ll wear through this one eventually but at hundreds of dollars less than the dentist I’ll take it! Really well made, great fitting night guard.

  • Gina Celeste

    Absolutely love this guard. I’m a heavy grinder but I cannot wear a hard guard. The 3mm soft guard works perfectly for me. This is my second one. The last one took about 18 months to wear through. Not bad and so much cheaper than the dentist. 5 stars!!

  • Katelyn M.

    Impossible to get a good impression! You guys sent me THREE kits and said none of the impressions were good enough. REFUND PLEASE

  • Robert Santos

    Fits well, stays in place, comfortable. A++++

  • Jacob Moylan

    My dentist found some damage on my teeth from grinding. He recommended Sentinel as an affordable option. I checked out the reviews online and they’re amazing. I’m grateful for the recommendation. The night guard is slim and fits perfectly to my teeth. It is a quality product.

  • Faith

    Jaw pain and headaches are GONE! I grind my teeth and have some TMJ-like symptoms. This guard makes my morning so much better. My jaw and I thank you!

  • 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.
