Is Tap Water Good For Preventing Cavities? The short answer is Yes… It seems to be a fad to refuse drinking tap water, and the use of bottled water has become more popular among the public. But is this wise? Not as far as your teeth are concerned. The metropolitan water supplies including that of Los Angeles County monitors the amount of Sodium Fluoride output, adjusting the amount to .8ppm to 1ppm. At this concentration fluoride bonds with developing enamel making it stronger and more resistant to cavities.
Typical spring bottled waters are not monitored and can have too little or too much fluoride. Too little will not give you the benefit of strengthening your teeth and too much can darken the teeth. It’s especially important to intake the optimal level of fluoride during the stages of tooth development between 3 months after conception to 15 years of age. Granted the tap water can be improved in purity and taste but that is a whole other post in itself. Stay tuned for next week’s post on How to Filter Tap Water Without Losing its Benefits.
