Drinking water and staying hydrated is an essential part of being healthy, but picking up any brand of bottled water to reach your suggested daily intake might not be the smartest move. Many bottled water brands have acidic pH levels and added fluoride, which can be extremely damaging to your teeth.
‘If the bottled water has a pH lower than 5.5, then it has the ability to dissolve enamel, which is the hard protective outer layer of your teeth and the hardest substance in the human body,’ Robles says. That pH level varies between brands because of the different processes each company uses to make the water clean enough to drink. The added chemicals and filtration systems used ultimately affect how the water tastes and its final pH level.
