> TIL that bottled water promotes tooth decay (by displacing flouridated tap water consumption) The elite-branded bottled water that go to lengths to set themselves apart from tap water (spring-fed-only, or rain-only, or some other esoteric, "natural" source) will not have fluorine. But many a budget-brand is simply expensively-packaged municipal tap water, and about 2/3 of municipal tap water supplies in the US are fluoridated. I suspect it is a relatively safe bet that when at a department/grocery store, if you simply pick up the house brand bottled water, it will be sourced from municipal tap water and fluoridated.
