It took him 10 years, but Howard Wright, DMD, an inventor and retired dentist, has finally achieved his goal of creating a toothpaste that changes color as you brush.
The toothpaste is dispensed as twin streams of red and blue toothpaste; as the child brushes, the colors mix to form a vivid purple, the company said. To prevent the colors prematurely mixing, the Vortex toothpaste tube has an interior barrier to separate them.
Vortex toothpaste retails for $6.95.
