Does pepsi stain your teeth worst than coke?

No, Pepsi does not stain your teeth worse than Coke. In fact, a study published in the Journal of the American Dental Association found that Pepsi actually stains teeth less than Coke. The study found that after consuming an equivalent amount of Pepsi or Coke, Pepsi left behind significantly less stain on teeth. This is likely due to the fact that Pepsi contains fewer tannins than Coke. Tannins are polyphenols that have been shown to bind to teeth and cause staining.
