"This has been a problem since I was a kid. I bite the inside of my cheeks until they bleed. I do it in my sleep so I am unaware of it. I've tried a lot of methods to stop the cheek biting. I think I do it more when I'm stressed. I bought these dental guards because I can't seem to stop on my own. I can sleep with them in comfortably. I can't tell you how nice it is to finally have my cheeks healed up. I would highly recommend this product for anyone that has the same issues as me. 10 stars!!!!"

"This is the first product I have found that actually works! I am a chronic tongue biter and have damaged the edges of my tongue. My tongue bleeds and is very painful. The soft dental guards are comfortable. It took me about a week to get used to sleeping with them comfortably. They are thin and my tongue has quickly healed. I cannot express my gratitude and the relief I feel. Thank you!"
