Try Plackers brand "Grind No More" They really do the trick for me and what I love about them is that I can wear them on the top teeth — much more comfortable than the lower. Also, they are very inexpensive since if you soak them during the day in something antibacterial that doesn’t mess up the material (for me non-alcohol mouthwash works) then they last many, many nights instead of the 3 nights advertised.
