The reduced staining capacity of iced tea goes double for store bought iced teas like Snapple, Arizona, Lipton, etc. Processing for bottled teas tend to filter out even more staining molecules before they make it to the store (probably to keep them less cloudy). Some studies haven’t even been able to find measureable levels of the major tooth staining molecules like theaflavins in store bought iced teas.
Enjoying iced tea is one great way to avoid excessively staining your teeth from tea, but be sure to watch out for overly sugary teas. All you sweet tea drinkers out there still need to pay attention to frequent sugar consumption to keep your teeth healthy.
