Best night guard ever!! Hands down. Better than my dentist. The company is professional, prompt and courteous. Most of all, they make an excellent product. I have recommended to multiple family members and friends. Keep up the good work Sentinel!

Fast and affordable. Great delivery service for custom night guards. My dog loves these lol so it's a good thing I have found an alternative to my expensive dentist! Thank you!

Thumbs up!! Went through a different company initially. It didn't pan out. Won't go into the story with that but this was a much better experience. The night guard is slim despite it being the thickest one. It covers about halfway up my teeth. Not too tight. But most importantly I'm not grinding my teeth anymore! Thank you.

Teeth impression kits arrived quickly. They supply an extra putty pack for a re-attempt. I ordered a lower guard so I did take 2 impressions of the lower teeth and sent in a picture to the email. They replied almost immediately with a yes to the impression picture. Received the guard in the mail within about 1 1/2 weeks after sending in the impression. Guard is thick and durable but that's good because I'm a heavy teeth grinder. It took a few nights of wearing it to get used to it as this is my first experience with a custom made night guard. I have worn the cheap plastic ones from the store and they're not comparable to the quality of this one. Very satisfied with the experience. A++++

Last year I spent $600 at my dentist for a new night guard. I've ground through several of them over the years, and this one was no different. The custom guard developed a crack within a few months. Instead of spending another $600 or more for a new custom night guard, I read a review about this being a really great alternative to the dentist. The instructions were easy. I took the teeth molds in about 10 minutes and mailed them back in. I like that they ask for both impressions to make sure the bite is correct. Received the guard and it was perfect. It's better than any of the expensive night guards I've gotten through my dentist. The guard fits snugly on my teeth and is very comfortable to wear. I recommended it highly.

GREAT PRICE! SHIPS ON TIME! I use this bite guard because I have battled chronic TMJ & they are a lot cheaper than the ones I get through my dentist. Plus they come with a 1 year replacement warranty. I generally have a great experience with this brand. I also use the teeth whitening. Works very well for when I need to whiten my teeth!

Outstanding product. Outstanding customer service! Let me start by saying that this guard makes sleeping a breeze. It's an excellent guard for the money. I have no complaints about it whatsoever. In the past I actually used a boil and bite but wished I had the Sentinel brand guard since they are of much higher quality. I finally pulled the trigger and it's a true lifesaver. More importantly, let me mention how much Sentinel stands behind their product. When an issue came up about the impression not holding well enough to remove from the tray, I contacted Sentinel and with no questions asked they stood behind their product and rushed me a new impression kit. This type of customer service only comes from a “top-shelf” company that is very secure in the quality of their products. I recommend the company for having the high moral and integrity standards that I wish all manufacturers had. Thank you Sentinel

Easy to use. Super easy to do at home. You can email a pic of your teeth impression to make sure it looks good before mailing it in. Fast response times, great fitting product. Would recommend.

You get what you pay for? This time I got A LOT more than what I paid for! This is probably one of the best night guards I've used thus far. I purchased this to help me with my severe teeth grinding and have found it extremely valuable for my teeth and jaw. No more pain in jaw. Teeth sensitivity and headaches are GONE!

Genius! I'll never buy those cheap night guards from Walgreens again! I know some people that are vehemently against wearing a night guard because they've never found one that's comfortable enough. I tell all of them to give Sentinel Mouthguards a try. My only word of caution is to pay attention to the directions before mixing the putty. The putty will harden fast! I love these and for the price, I might buy a backup for travel.
