‘You might want to think twice about drinking fruit juices. Even the ones touting 100% juice have about as much sugar as a can of Coke; because juices don’t have the fiber you get from eating an actual fruit, you’re getting the calories without feeling full. As if the sugar in fruit juices (and sodas) […]
Consider, first of all, the sugar. While your cranberry juice cocktail might taste too tart without several tablespoons of sugar, that sweetening comes at a price, since the bacteria in your mouth love sugar. The more bacteria feeding and breeding, the more damage to your enamel, the more plaque buildup, the more bad breath, and on and on until cavities, root canals
and dentures. Sugar is bad, but the acidity is worse.
If you don’t know anything about chemistry, acidity has to do with a substance’s pH; a gallon of pure water at room temperature is neutral with a pH of 7, while battery acid is a 1. Anything 4 or less will damage your enamel, which, in terms of soft drinks, means water, milk, and root beer are about the only ones you can drink without significantly harming your teeth. Orange Juice has a pH of around 3.5. Cranberry juice’s pH is about 2.9, and if you really like sour stuff, lemon juice is between 2 and 2.5!
Choosing juice over soda is probably a better option, but you should still treat it like the sugary concoction it is and at least drink some water after. Brushing, as usual, is still your best defense.’
