Does Zoom Work on "Gray" Teeth? (photo)

Hello there,As a cosmetic dentist in St. Louis, I would not recommend Zoom whitening on gray teeth.  Any improvement would likely be unnoticeable to you or anyone else.  In this case, I would consider veneers or not doing anything.  I know that you are 62, but it's amazing how many times I have had 55, 60 and 65 year old females that get veneers and love them.  Your teeth, your hands and your weight show your age more than any other visible feature.  When I place veneers on patients your age, they typically notice a 10 to 15 year younger appearance.  Great question and good luck with everything.

Zoom, as well as any bleaching system on the market, affects every patient differently. They all work BEST on yellowing teeth, and they are all LEAST effective on grey teeth. That being said, you might get a slight improvement, but don't expect a bright white tooth.

Different types of whitening are primarily time versus concentration in how they work. Grey teeth is usually increased translucence though sometimes it might be exposure to metals, particularly tin. While I haven't read any studies, my personal experience is that Zoom is a bit better than tray whitening with gray teeth - likely the intensity changes the translucence more. My advice is to do it better you do the crowns. Good luck!
