I found this for just under $25 at Walmart. I had seen a magazine ad previously but hadn't intended to purchase this product. I was in the toothbrush aisle when I saw it & decided to give it a shot. many years ago, my dentist had c suggested using a mouth guard to reduce nighttime teeth grinding. I have used that strategy in and off over the years but, though cheaper than a bite plane, it definitely leaves much to be desired. So far, this product is great. It was extremely easy to fit & I definitely appreciated NOT having to put it in boiling water! It is very low profile & the design at the front of the piece seems to keep it in place (rather than allowing you to unconsciously spit it out in the night). It fits along your lower teeth so it's quite different than anything I've used previously. I definitely recommend this.
