6. Drinking Water Lowers Your Mouth pH level
Most of us probably do not give much thought to the pH level of our mouths. A neutral pH level in your mouth is 7.0, but acidic foods and beverages can alter that. This can lead to bad bacteria growth and tooth decay.
However, fluoride protects the tooth enamel against the acids that cause tooth decay. More than 90 national and international health professional organizations, including Health Canada, the Canadian Public Health Association,the Canadian Dental Association, the Canadian Medical Association, the U.S.Food and Drug Administration, and the World Health Organization. All these organizations support the use of fluorides to prevent lower mouth pH levels.
