If you are a regular user of whitening strips, you will be delighted to learn that Crest has recently launched Crest 3D White Whitestrips with Light. Yes, just like at the dentist’s office! The blue LED bulb device is designed to target yellow spots to brighten and whiten our teeth. The device is used on top and bottom strips for one hour a day, for ten consecutive days. Faster, simpler and certainly more affordable than going to the dentist, we love this technological breakthrough that literally makes us want to smile!
