Coffee - 4/4 strikes
It’s hard to hear. I know. But facts are that coffee contains dark color pigments, it’s acidic and most people drink it piping hot.
Tea - 4/4 strikes
Black coffee in particular can cause staining because it has more tannins. English teeth anyone?
Soda & Energy Drinks - 3/4 strikes
No surprise here. They’re acidic, usually contain artificial food dyes and people drink them cold. They are also packed with sugar, which causes decay.
Balsamic vinegar - 2/4 strikes
It’s delicious, but it can also stain your teeth! Balsamic vinegar contains dark pigments that stick easily to the enamel due to the fact that this product is highly acidic and rich in sugar.
