EASY TO USE AND STURDY 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.

I bought this guard for Jiu Jitsu training. I didn't want a super thick guard and I love that this company give you the option to choose how thick it will be. This one is a 2mm. It offers solid protection. I can speak clearly and it does not fall out while I'm training. Had some trouble with the impression. Had to do it 3 times to get a good fit. I'll say this: Be sure to get the gum line when you're taking your impression. That's what they're looking for. They said mine was too shallow the first two times. Even though I had some fitting trouble I'm very pleased with the final product.

Great quality for the price.They keep the impressions on file for 1 year in case I need a replacement set. They send you the kit for your impressions first. There are 2 different sized trays and extra molding in case you mess up. It’s really easy to do, and my retainers were mailed back within a week or so.

I have tried night guard from other online manufacturers for heavy teeth grinding and this is the best. Fit is good, fast delivery.

I love these custom guards for cheek biting...I was a bit hesitant to order because I need to wear them all the time as I'm an excessive cheek biter.I was worried they wouldn't be durable enough for night and daytime use but I'm impressed. After a few days, I felt total relief. They are very durable and well made....I will continue to purchase from this company

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!

If you have a cheek biting issue like me, this is the product you need.

VERY COMFORTABLE This is my honest review. I have crooked teeth and was very concerned about how this would fit over my teeth. I took a bad impression the first time around. The team at Sentinel sent me a new kit. They did not charge me for the 2nd kit. I took my time reading the instructions and got a good impression. I usually work about 7 to 8 hours at my computer per day. I wear this guard during the day and it works well. My jaw feels better. I feel good knowing I'm not doing damage to my teeth now. I bought 2 more of them during their xmas deal as backups. Go for it. I definitely recommend them.

Needed an adjustment. They had me print out a tooth chart and circle the teeth area that the guard was too tight. I sent it in and it was very quickly returned to me with the correct adjustments. My guard fits great now and I am pleased with the service.

Beautifully made. I have to admit I was a bit skeptical in the beginning. It was a bit stiff and uncomfortable but then after a few nights it just seemed to loosen up and adjust to my mouth. For the price versus what my dentist wanted to charge me, I feel good about my purchase. It really is a nice mouthguard. I appreciate the extra attention to the shape. I've had mouth guards in the past that they cut straight across and even had jagged edges. This one is nicely done. Definitely worth it.
