1Technical report How does the blue light whitening technology work?
The blue light (450-470nm range) serves two purposes:
- It activates the PAP whitening agent in the toothpaste, accelerating the oxidation of stain molecules on the tooth surface;
- The patented light guide filament channels light through the bristles, ensuring the light reaches between teeth and along the gumline where stains accumulate. In an internal irradiance comparison test, Brush Pro's blue light output was measured against a leading whitening device (Colgate) to verify sufficient light intensity for whitening activation. The light is automatically activated during brushing cycles.
