What do Powerade, Gatorade, Vitamin water, Lemonade, Energy drinks, Snapple and Sprite have in common?
They are all cavity causing if one consumes these popular drinks in large quantities.
Most people intrinsically realize that soda is bad for their teeth. The average middle school student (or at least my kid) has done the baby tooth in a cup of soda experiment, so in general most of us recognize that carbonated sugar water is highly acidic and can lead to one’s tooth slowly dissolving away.
A recent article in the Journal of the American Dental Association explores this even further, investigating the pH of hundreds of beverages. pH as one may recall from chemistry class, is a measure of acidity or alkalinity of a solution. Low pH (less than 4.0) can lead to the destruction of tooth structure even in the absence of cavity causing bacteria. In short – acidity in drinks is not healthy for your teeth.
It might come as a surprise to a lot of people that there the vast majority of commercially available drinks such as sports drinks, vitamin waters, and ‘healthy’ fruit juices have very low pH’s.
The most acidic beverages tested (all with a pH less than 2.4) were lemon juice, RC Cola, Coca-Cola Classic, Coca-Cola Cherry and Pepsi.
And the least ‘acidic’ beverage tested? Municipal water from Birmingham, Alabama which at a pH of 7.2 proves that when it comes to healthy teeth, water is the way to go.
