According to the American Dental Association, the average 160-pound person should ingest about four milligrams of fluoride every day. This is why cities across the US fortify their drinking water with fluoride. In general, you can expect the water coming out of your faucet to give you about 0.7 to 1.2 milligrams per liter which, when paired with the fluoride content of a typical toothpaste, should be enough to give you the fluoride you need to maintain strong and healthy teeth.
Unfortunately, some people turn to bottled water for much of their hydration. They are attracted to the superior purity that such water allegedly has. Though some are indeed purer than others, this purity is not necessarily doing you many favors. The average bottle of water gives you only 0.3 milligrams of fluoride per liter, making it far more difficult to remineralize your teeth and prevent cavities.
