By now you should probably know to never believe anything you see on the internet or social media without checking into the facts behind the claim. Over the last few weeks, the web has been abuzz with claims that the colored squares at the end of tubes of toothpaste clue consumers in to the chemical make-up of the product. I.E. - one color supposedly means that the product is organic, another color means that it includes some chemical or another, etc.
With just a cursory search into this subject, I can boldly inform you that this is a myth.
