COMPLETE TEETH WHITENING: STYLSMILE Brush Kit includes Sonic toothbrush with built-in Blue Light technology & PAPtech toothpaste. The Stylsmile toothbrush has blue lights in the brush head which energise and accelerate the PAP whitening process.
I saw this featured on the gadget show and decided to give it a try. I have used it about 10 days and my teeth look slightly whiter. It's a shame the manufacturer didn't include a shade guide to measure results against.
