Does Reverse Osmosis (RO) remove fluoride from water?
Crescent Hills’ Reverse Osmosis water purification system can remove over 90% of the fluoride in water. Fluoride occurs naturally in both the earth and water. It is often artificially added to municipal water supplies to help prevent tooth decay. The long-term effects of fluoridation of public water, however, is still unknown.
Recent studies indicate that fluoridation of public water may not be as healthful as originally thought. It may have little benefit for teeth after childhood. Humans only consume about 2% of all fluoridated water. So, there are more effective alternatives to fluoridating an entire water supply. For example, the application of fluoride tablets and vitamins may provide a safer, more precise dose to your children. Also, most toothpastes today contain fluoride. Fluoride can also be added to salt in the same way it is added to water. But, unlike public water, salt intake can be monitored individually.
Isn’t fluoride necessary to reduce cavities?
Fluoride toothpaste is perhaps the best solution. It is the most widely used and rigorously evaluated of all fluoride treatments. Its introduction in the early 1970s is considered the main reason for the decline in tooth decay in industrialized countries. Toothpaste appears to be the only common factor in those countries. It is the only realistic fluoride strategy in many low-income countries, where lack of infrastructure renders fluoridation of public water infeasible.
Brushing with a fluoride toothpaste relies on individual and family behavior. Among the poor, it is generally not affordable. Fluoride toothpaste prevents about 25% of cavities in young permanent teeth. Its effectiveness is improved if higher concentrations of fluoride are used, or if the tooth brushing is supervised. Fluoride mouthwash and gel are about as effective as fluoride toothpaste. And fluoride varnish prevents about 45% of cavities. By comparison, brushing with a non-fluoride toothpaste has very little effect on cavities.
So, yes fluoride is necessary for reducing cavities. But there are better methods for delivering fluoride to the teeth than the fluoridation of public water. The removal of fluoride from your water supply by your Crescent Hills system will necessitate your using other, more effective ways of getting fluoride to your teeth.
