Customer ratings & reviews

I've given 5 stars and if I could give more, I would! I love Sentinel Mouthguards; their customer service, this product (it's the only one that I've found that actually WORKS) and the timeliness of the experience. The teeth impression instructions and extra tips are fantastic and very easy to follow. The customer service team is so lovely. I gained instant confidence in this company as soon as I had a chat. The product is great and brought so much relief to me. I'm grateful <3 Thank you!

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.

A bit time consuming but worth it. The guards are a big upgrade from the ones I was using from Walmart. While it is a bit time consuming to have to make the molds then wait for the product to come, this is your best bet when compared to the cheap ones from the store. If you're looking for something with high quality but accessible price, this company is a good one.

I have to say this company is awesome. They get go above and beyond the call of duty. This is my 2nd time ordering from them and they never let me down. Their work is always on point. They will keep doing it until you are satisfied. Thank you so so much!

The process was simple, fast and the results were fabulous! The guards were high quality. My tongue has healed and currently I don't wear the guards as I don't need them. If I bite my tongue again, I will wear them to allow the area to heal. I am extremely pleased and would recommend!

Works! I use this all the time. It works very well to prevent me from creating sores on my tongue. It tackles the problem. GOOD STUFF!

I purchased this because I have an area in my cheek that I couldn't stop biting. I was worried about the time it would take so I did the expedited shipping option. Kit arrived and process was pretty straightforward. Quick turnaround time and great product. It really does work! I did need to wear my guards during the day and night at first but once that area healed up, I quit wearing them all the time. Good to know I have them if and when it happens again. Thank you!

For teeth grinding too! I have a whole lot going on in my mouth apparently including (but not limited to) tongue biting and teeth grinding. Thank you universe for giving me a double whammy! Maybe this is some strange after-effect from back in my heyday (hello drugs!) These guards fit on the upper and lower teeth like a glove and protect me from both of these harmful involuntary things. My tongue has started to heal and my jaw doesn't feel stiff anymore upon waking. Process was fairly easy. Happy customer! Thank you!

bought this for my husband because he would rather suffer in pain lol. We took his impressions and sent them off. Fast delivery and he was impressed with how comfortable the guards are. He wears them at night only and his cheek area that was REALLY bad has completely healed. Best on the market! Fast, long lasting relief. Thank you Sentinel Mouthguards
