MY NEW TOOTHBRUSH PROMISED WHITE TEETH IN 28 DAYS. AFTER JUST TWO WEEKS THREE PEOPLE COMPLIMENTED ME ON HOW WHITE MY TEETH WERE. AND I STILL HAVE TWO WEEKS TO GO. I WOULD SAY THE NAME OF THE TOOTH BRUSH BUT SINCE THEY ARE NOT PAYING ME, LET ME JUST SAY THIS: IF YOU ARE LOOKING FOR A TOOTHBRUSH THAT WHITENS YOUR TEETH: IT IS OUT THERE.
