You are doing such a wonderful thing!! My husband has been using your system for 10 months. He is a night teeth grinder and was having issues with wearing the enamel on his teeth before he started the system. He no longer has any more wear of his teeth, and says that his teeth feel much stronger. The other really neat thing is that my husband has always been dissatisfied with the color of his teeth (yellowish). He tried crest white strips for approximately 7 days without any improvement in color. Since he has started the system, the color of his teeth has improved immensely!! They are whiter than they have ever been!
