i really havent paid that much attention. i am not one to worry about what they look like. i am just happy they are not poisoning me now.
they have shown different shades along the way. one thing that has been a constant, besides the over health improvement of gums and mouth is my teeth have become much more dense looking. they used to look transluscent and mottled(more fluoridosis) and now they are very opaque and even in color, albeit not exactly white. i drink coffee so that may be what i get until i quit that.
