Yes, most water bottles have fluoride. It’s a chemical added to the public drinking water supply for dental health. Bottled water companies also add it as an additive to their products. If you’re wondering whether those little containers of flavored waters from your grocer’s refrigerator section contain flouride, this is one question that can’t be answered by looking at the ingredients list on the label because those products don’t legally need to disclose their fluoride content – they’re not required to include any ingredients other than “purified water”. Drinks that are labeled ‘spring’ or ‘artesian’ may be more likely than others (i.e., bottled waters) to contain added flouride, mineral salts and/or “natural” flavors.
