I'm loving DaVinci Teeth Whitening in my clinic. Personally, I've seen fantastic results with this safe and effective system, maintaining my own bright smile with treatments every six months and experiencing zero sensitivity. The DaVinci process is a simple, three-step approach combining a specialized LED blue light with an all-natural whitening gel. It gently lifts years of stains, and as a bonus, the blue light also contributes to improved gum health. It's a comfortable, hour-long treatment – perfect for enjoying a podcast or audiobook – and it effectively counters the effects of my daily coffee indulgence. This is a one hour treatment, I block an hour and a half, to be safe.
