    Best teeth guard I’ve ever worn! Slim design, light and fits like a glove! The one from my dentist didn’t compare to this one. Comes with a nice storage case as well. Thanks guys for an amazing product!

  • Jamey R

    Wow! Just terrific customer experience all around. I received my night guard today and if fits perfectly. Thank you!!

  • Dan C.

    Taking the mold of my teeth was a lot easier than I expected. The impression kit came to my house within just a few days of ordering. I watched the Youtube video and looked over the instructions that came in the box. Easy and straight forward. This process ended up being SO much less expensive than the dentist and I love how it fits and feels. I wear this while I’m lifting weights too. An extra perk!

  • Shawn West

    I used to buy one of the drugstore mouth guards every couple of months and I’d wear a hole through it in no time. This is not the case with these custom made ones. The quality of the plastic is higher and much more durable. Still less cost than the dental office versions. I will order from this company again. Best mouth guard ever!!

  • Melanie Jones

    These are custom made and fit like they are exactly for your teeth. They are thick enough to be durable for a heavy teeth grinder like myself and I was happy to learn that they are the safest night guard online. Staying away from BPA, MMA and Pthathlates is very important to me. They seem to keep the shape well as it’s been about 6 months since I ordered and still fits like a glove. I’ll update if something changes. I am using this for severe nighttime teeth grinding.I am very happy with this purchase and will be buying them again!.

    In this review, I compared to OralB brand from Wal-Mart to Sentinel Mouthguards. Without a doubt, there shouldn’t even be a comparison. I didn’t know what I was missing and I don’t know why I took so long to switch to a custom made guard. I used to go through several of the Oral B’s from Walmart per year and I thought I was saving money.Oral B guard doesn’t stay in place, the material is cheap and if you grind through it oh well. My vote by far is for the Sentinel brand. I use the night guard everyday so cost and effectiveness are important.

    This 3mm soft mouthguard is very sturdy. It has been very handy for me and much less expensive than my dental office. Teeth impression kit came with extra putty pack for a second attempt which I was grateful for. Process was overall quick and easy. I’m happy with my purchase.

  • Holly Lind

    Can’t stop wearing it! Has helped me so much. So glad I decided to wear this product because I worry about my teeth during the day and at night. Comfortable, light and easy to mold to your teeth. Great product!

  • Jeffrey Thomas

    Dog ate my dentist made mouth guard so I wanted to give this night guard a shot. I have a lot of discomfort from clenching my teeth at night. Affordable and comfortable! I have to use this all the time and glad it’s comfortable!

  • Gary Paluzzi

    FAST DELIVERY! I’m a terrible teeth grinder and have chewed up many store bought brands. Don’t waste your time on one size fits all guards. This night guard is super comfortable. Service was fast and friendly. Will update if I see signs of wear. So far, so good!

  • Julie T.

    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!!
