Stained Teeth

Chicago, April 3: Drinking white wine instead of red to prevent harmful buildup on pearly teeth is not a wise idea because white wine has the same damaging effect on teeth as red wine

The researchers found that acid contents in white wine can potentially create rough spots and grooves in teeth that allow chemicals in other beverages, such as coffee and tea, to penetrate deeper into the teeth, triggering the risk of dark dental stains.

A: Like coffee and colas, tea can stain teeth, although it's not as big an offender as tobacco (smoked or chewed). Any food or drink capable of staining clothes or carpets can also stain teeth -- that includes fruit juices, red wine, blueberries, soy sauce and curry.Good-quality green tea that is really green in color is less likely to stain teeth than inferior grades of "green" tea that looks brown when brewed.
