Tea comes in a variety of types and colors, so you really can’t judge how much tea might stain your teeth solely based on the quantity of polyphenols. Even though a particular kind of tea might have more polyphenols overall the type of stain that results might not be as visible.
For instance white teas which tend to have the highest polyphenol content produce more of a yellow type of stain, which is less noticeable than black teas which produce brownish-blackish type stains. Fortunately, with tea we have some flexibility to choose teas that have the health benefits of polyphenols, but might produce less noticeable stains.
The quickest way to judge what color staining the tea you’re drinking will produce on your teeth is to look at the color of the tea in your cup. This method works really well, but as with anything there are exceptions.
We are going to be diving more in depth with our analysis of tea stains on your teeth of the next few weeks so stay tuned it should be fun.
