As delicious as coffee is, I am sure that everyone is a little worried that they will be staining their teeth. The truth is that not all coffees stain your teeth the same. Let’s take a look at how iced coffee compares to your average cup of joe.
Traditional cold brewed coffee relies on time, rather than heat, to transfer coffee flavorants to your drink. As a result, cold dripped coffee not only contains less polyphenols, but also up to 70% fewer acids too.
The iced coffee that you will likely get at your corner coffee shop won’t be cold dripped, but will be an iced espresso drink. This too contains less polyphenols simply because espresso has less than drip coffee, about a third of what is found in drip coffee.
Ironically, though polyphenols stain your teeth they are quite good for your general health and even make your teeth more acid resistant. Ever wonder why people on national geographic with really stained teeth don’t have cavities?
