Bottled water continues to see growth in annual sales beating out the once more popular choice of carbonated soft drinks. Surveys show consumers prefer bottled water because of taste, quality, convenience, and safety. Many consumers also list bottled water as a healthy beverage alternative. However, consumers are unaware of the potential negative effects of bottled water due to the varying pH levels. Two studies, conducted in 2015 and 2017, tested the pH values of popular bottled water brands. Results from testing bottled water showed a wide range of pH values, from 5.16 to 10.38. These results are alarming when it comes to the possible erosive effects of bottled water consumption on the teeth as well as overall dental health. Dental professionals should be knowledgeable in identifying the early, clinical appearance of erosion to educate their patients of the effects of acidic bottled waters on their teeth.
