![]() #SCIENCE TAB SOAD FULL#No one swishes soda in their mouth for two full days, as was the case with the study, but the corrosive effect of soda starts nearly immediately, Jain's research points out, and increases with time. Milk contains minerals, proteins, vitamins and, most importantly, calcium. In 2003, Americans drank an average of 46 gallons of soft drinks and 22 gallons of milk. In 1966, Americans drank, on average, 20 gallons of soft drinks and 33 gallons of milk. In the past 40 years, many Americans have swapped nutrient-dense milk for sodas and other beverages that are mostly bereft of nutrients. Cavities and tooth decay tend to hit targeted areas, such as pits, grooves and spots where teeth are adjacent). (Dental erosion refers to the action of acid on the entire tooth surface. The reason for the reduced acidity is that root beer is often non-carbonated and contains no phosphoric or citric acids.Ī 2006 study reported that orange juice and sports drinks also reduce the surface hardness of tooth enamel, but a cola reduced more-the dentin, surface enamel and two additional dental components. Root beer was found to be the least acidic of all soft drinks, with a pH 4.038 for the Mug brand, Jain and her colleagues found. "The bottom line is that the acidity in all soft drinks is enough to damage your teeth and should be avoided," Ross said in a prepared statement. Citric acid is the most erosive acid found in soft drinks and is the predominant acid in non-cola drinks. The type of acid in the soda, level of soda and calcium content are also factors. The results show that a soda's acidity is not the whole story when it comes to tooth erosion. Pure water at room temperature has a pH of 7.0. Cherry Coke was found to be the next most acidic (pH of 2.522), and Coke was the third most acidic soda tested (pH of 2.525).īattery acid has a pH of 1.0. (Other sodas brought about losses in the enamel weight in the range of 1.6 percent to 5 percent).ĪGD spokesman Kenton Ross said that RC Cola was found to be the most acidic soft drink studied, with a pH of 2.387 (the pH scale ranges from 0 to 14 for most liquids, with 0 being the most acidic and 14 being the least acidic-or most alkaline). The result was that the teeth immersed in Coke, Pepsi, RC Cola, Squirt, Surge, 7 Up and Diet 7 Up lost more than 5 percent of their weight, according to the report by Poonam Jain of the Southern Illinois University School of Dental Medicine and her colleagues. Then slices of enamel from freshly extracted teeth were weighed before and after being immersed in the soft drinks for 48 hours. The study measured the acidity, or pH, of 20 commercial soft drinks, including Coke, Pepsi, 7 Up and their diet versions, immediately after cans were opened. ![]()
