Customer Reviews
Love my new mouthguard!
Oh my goodness, I am so happy with my new Custom Athletic Mouthguard! It fits absolutely perfectly and is so comfortable, way better than anything I've ever bought in a store. The color I picked looks awesome too. I used it for my last game, and it felt like it wasn't even there! I will definitely be getting another one when this one eventually wears out. You guys are amazing!
Good quality, fast shipping
Ordered a Custom Athletic Mouthguard. The impression kit arrived quickly. Sent it back, and the mouthguard came faster than I thought it would. Fits perfectly. Happy with the purchase.
Absolutely love my new guard!
I just received my 1mm Thin Night Guard and it's fantastic! I barely even notice I'm wearing it. The impression kit was super easy, and the instructions were clear. Shipping was faster than I expected, and the fit is just perfect. I sleep so much better now without grinding. This store is my go-to for sure, and I've already told my sister about them!
Reliable as always
This is my third order from Sentinel Mouthguards, this time for an Extreme Durability Night Guard. My first one lasted ages, and the second was a Custom Athletic Mouthguard for my son which he still uses. The process is always consistent; the impression kit works perfectly, and the finished product always fits. It's why I keep coming back. They're dependable and the quality is consistently high, which is what you want for something custom-made like this.
Detailed review of my experience
I ordered an Extreme Durability Night Guard. The ordering process online was very smooth; their website was easy to navigate. The impression kit arrived within a few days, and the instructions were clear, with a video tutorial link which was helpful. After sending back my impressions, the custom guard took about two and a half weeks to arrive, which was in line with their estimated delivery times. The fit is excellent, very snug but comfortable. Cleaning is simple with the tablets I also bought. I had a quick question about cleaning when it arrived, and customer support responded to my email within a few hours. Overall, a professional service and a high-quality product that feels very robust.
Solid product, slight delay
Ordered an Upper Night Guard, the Dual Laminated one. The impression kit was straightforward to use, and I sent it back without any issues. The guard itself is comfortable and seems durable, much better than the over-the-counter ones. It took a bit longer to arrive than I initially thought, maybe a week past the estimate, but customer service was helpful when I inquired. Overall, I'm satisfied with the product and the fit, just wish shipping was a touch faster.
Night guard is really good
I got the Hard Dental Night Guard because I grind my teeth a lot. It was pretty easy to do the impression kit at home, just followed the instructions. The guard itself fits nicely, way better than those boil-and-bite ones. Sleeping much better now, didn't even realize how much the old one was bothering me. Totally worth it.
My third order, still great
This was my third time ordering from Sentinel Mouthguards. I needed a new 1mm Thin Night Guard because my old one (from them too) finally wore out after a few years. Just like the last two times, the impression kit was straightforward, and the new guard fits just right. I keep coming back because their products are consistently good and last a long time. No complaints at all, they're reliable.
Got my night guard
So I finally got around to ordering one of these night guards. I went with the Soft Dental Night Guard, seemed like a good starting point. The impression kit wasn't hard to do, just follow the directions. It came back and fit pretty well, feels good in my mouth. Way better than clenching my teeth all night. I'm happy with it.
Good value for a night guard
I was looking for a good deal on a night guard since my dentist quoted me a fortune. I ended up getting the Dual Laminated Night Guard during a seasonal sale. The price was really fair, especially compared to what dentists charge. The impression process was simple enough, and the final product feels durable. I feel like I got a really good value for my money here.

How long does it actually take to get one of these guards? I grind pretty bad and need something soon.
Anyone know if these are legit for FSA/HSA? My dentist charges a fortune.
Can you use like a military discount AND a seasonal sale code on the same order? Trying to save as much as possible.
How do these compare to something like ProTeethGuard or Sporting Smiles? Are they worth the extra cost?
Hey, I'm thinking about getting a night guard from Sentinel. Do they do any first-time buyer deals, or should I wait for a sale?
