Does the New Zoom WhiteSpeed Machine Still Use Gel, or is It Just the Light?
I have heard the new Zoom WhiteSpeed machine creates less sensitivity than the traditional Zoom machine. What I have read online says that "blue light emitting diodes" whiten the teeth.I thought light was used in the traditional machine too. Is a gel still applied to teeth, or is the whitening completely achieved by the lights?
It's the gel, not the light, that gets the job done.
