Dentists across the country are the first to warn against drinking too many acidic drinks, as they have been known to cause significant problems to teeth in the form of acid erosion of enamel (enamel starts to erode at a pH of around 5.5). Since acidic beverages can be bad for teeth, dentists often recommend drinking water, which has a neutral pH of 7.0 or something slightly basic, such as milk.
However, a recent research study conducted by The Daily Mail Health has concluded that some bottled water may be more acidic than we previously thought. According to their tests, many brands came in with a neutral or slightly basic pH around what most people would expect, including Poland Spring, Fiji, Evian, and others. On the other hand, there were some surprises, as some major brands of popular bottled waters registered an acidic pH of 4.0, similar to some cream sodas, root beers, and tomato juice.
In the end, it’s important to drink plenty of water for both your dental and overall health. The safest choice for water is tap water that has been treated with extra fluoride, which has been known to protect enamel.
