A recent study published in BMC Oral Health evaluated the efficacy of community water fluoridation in the prevention of dental cavities. The study looked at children in Juneau, Alaska and compared patients from 2003 and 2012. The city ended its community fluoride program in 2008. The researchers found that following the end of the water fluoridation program children experienced one additional cavity related procedure per year at about $300 or more per child.
Since 1950, the American Dental Association (ADA) has advocated the fluoridation of community water supplies as safe and effective in preventing tooth decay. In order to reach the optimal range for dental health, fluoride must be at a level of 0.7 to 0.8 parts per million.
After reading this article, our main question was about the water in the City of Oceanside. We found that Oceanside has three main sources of water: raw water treated at Weese water treatment plant, groundwater treated at MBDF and water purchased from SDCWA. Fluoride is not added to the water treated at Weese or MBDF. The level of naturally occurring fluoride in this water averages 0.3ppm. Water that is imported from SDCWA has added fluoride. Interestingly, the area south of Oceanside Blvd receives fluoridated water with an average concentration of 0.8ppm. The water delivered to all other areas of the City has an average fluoride concentration of 0.3ppm.
So what does this mean for you? Consider where you live in Oceanside and your source of water. Most people in the City of Oceanside will need to supplement with a fluoridated toothpaste and/or mouthwash.
