What’s your favorite drink doing to your teeth?

In 1942, the annual production of soft drinks was approximately 60 12-ounce servings per person.  In 2004, the Center for Science in the Public Interest has reported the total consumption of these drink for every man, woman, and child was approximately 68 gallons per year (Jacobsen, 2005).  And in 2015 Buzzfeed made a video to show avid soda drinkers what their drink of choice was doing to their teeth…

If short on time… from white to brown in 5 days…

My first reaction is fear. But fear isn’t particularly helpful.  Should we be too scared to drink sodas all together?  Do other drinks have this same effect? What is causing this damage? To better evaluate what to drink we need to understand our teeth.

Our teeth are a mineralized structure composed primarily of the hydroxyapatite crystal. This crystalline structure is composed of calcium and phosphate; it’s chemical formula is Ca10(PO4)6(OH)2.  The presence of more protective factors favor strong intact crystalline structure. A disproportionate number of destructive factors will favor the dissolution of the hydroxyapatite ultimately leading to a cavity.  When the pH in our mouths drop below the critical pH of 5.5,  destruction of tooth structure is favored. When the pH in our mouths drops to below a pH of 4 our teeth start to chemically dissolve even without the presence of bacteria (Dawes, 2003).

Acids are added to beverages and compose a flavor profile giving the beverage a distinctive taste. Acids provide a tartness and tangy taste that helps to balance the sweetness of sugar present in the beverage.

Phosphoric acid is added to cola drinks to impart tartness, reduce growth of bacteria and fungi, and improve shelf-life.

Citric acid, a substance naturally occurring in citrus drinks and added to many others, imparts a tangy flavor and functions as a preservative.

Malic acid occurs naturally in apples, pears, and cherries, and is added to many noncarbonated beverages such as fruit drinks, fortified juices, sports drinks, and iced teas because it enhances the intrinsic flavor. Malic acid also is added to artificially sweeten carbonated beverages to intensify taste and reduce the amount of other added flavorings.

So what is your drink of choice? Do you know the pH of your favorite drink?

While all nutritional labels have the grams of sugar clearly recorded, the pH of our favorite drinks is not as easy to lookup or reference.  Luckily, Dentist and Public Health Researcher Avanjia Reddy and her research team took on the task of measuring the pH of 379  commercially available juices, sodas, flavored waters, teas, and energy drinks.

My advice is to enjoy your refreshment, but know that along with all that tangy flavor comes the need to have habits to balance that acid.

I recommend drinking through a straw to minimize contact with teeth, rinsing with water afterwards, enjoying the drink with a meal as protective saliva flow increases with meals, and brushing and flossing well at home with fluoridated toothpaste to allow your teeth to fortify.
