The Daily Mail reported that it tested the pH levels of “popular brands of bottled waters,” finding some had a pH level of four. The article stated that beverages with “pH levels closer to zero are more acidic” and may erode dental enamel. The article reported that bottled water may also contain “insufficient amounts of fluoride.” Given this, a dentist quoted in the article discussed the benefits of drinking fluoridated tap water. The article also noted that the American Dental Association encourages drinking fluoridated water to help prevent dental caries.
Business Insider (8/11, Schmalbruch) reported that adding flavor to water, especially citric flavors, can lower the pH level, making it “more acidic.”
Additional information about fluoride and community water fluoridation is available at ADA.org/fluoride. The ADA Catalog also features the Fluoride Nature’s Cavity Fighter brochure. The Oral Health Topics on ADA.org provides additional information on dental erosion for dental professionals.
