I have use this for about 7 mos., on the 6th day of using this my teeth had lighted 2 shades I have a front cap, a bridge and a few other things. this product over the months have change everything with my teeth, sooo white and shiny if you are not getting good results it simply means you are not using it and if you shop around you can get a good price
