Does green tea cause teeth stains?
Drinking tea or coffee stains or discolors the dental plaque, but not the teeth itself. If the plaque is not completely brushed and flossed away within a 24 hour period, it begins to harden and becomes what is commonly known as tartar. This tartar is porous and further absorbs stains from other food products. Then a dentist clean your teeth, they remove the tartar and plaque. When the tartar and plaque go away, so do the teeth stains.
