Review on M3 Naturals Teeth Clenching Mouth Guard for Night, Dental Bite Guard for Night Grinding, Whitening Trays Night Guards for teeth grinding, BPA Free Mouthguard Teeth Grinding, 4 Guards in 3 Sizes by Ryan Foxz

My dentist tells me for years that I needed a face mask, but could not afford the ones that are professionally made there. I'm glad I stumbled across this as it's a quality product for a fraction of the price! I don't know why Revain is asking customers to rate this product's whitening abilities? Nothing on the packaging or instructions suggests this, but other than that it's absolutely gorgeous! Not only is it easy to mold, they offer two sets of moldable guards, one small and one large, so you can choose what works. The best for you! They have a reference to a product offering the next one for free and says that this product has a finite lifespan and needs to be replaced at a certain interval, which probably depends on the person and how much they sharpen or wear out the protection I think !
