Customer ratings & reviews

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.

These day guards are a good value. The other night guards are more to wear thru the night. The teeth impression shaped easily. I was happy to see they sent some extra putty in case I needed to redo it but I didn't have to. Got a perfect fit. Day guard fits well and I'm a happy customer!

This worked PERFECTLY. I clench my jaw during the day and at night and have sensitive teeth because of it. I had a $400 mouth guard from my dentist but it was so uncomfortable I couldn't wear it. I chose the 2mm thickness after talking to customer service. It's thin but the quality is still high. I will definitely never be buying guards from my dentist again. This is a wonderful product!

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

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 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

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

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!

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.

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.
