If there’s one thing you can probably get dentists in Joondalup to agree on, it’s that fluoridation of water is good for your dental health. So, what is water fluoridation and why is it so good for your teeth? Keep reading.
History of Water Fluoridation
Water fluoridation adds to the levels of fluoride that are already in water. This helps prevent tooth decay. All water already has naturally occurring fluoride. In the US, in the 1930’s, scientists found that people in areas with more naturally occurring fluoride in their water had less tooth decay. In 1945, the water in a few communities was fluoridated. It was so effective that fluoridation spread across the US rapidly.
By the 1960’s, fluoridation had spread to Australia and by the 1970’s, fluoridation became commonplace in Australia. Currently, more than 90% of the population enjoys fluoridated water.
The benefits of fluoridation are simple: less tooth decay, fewer extractions, fewer fillings and fewer trips to the dentist. Even though the benefits are common knowledge and well-documented within the scientific community, Australia’s Child Dental Health Survey examined 136,000 children in 2002, documenting whether or not they drank fluoridated water.
No matter what the other demographic factors, including where they came from and how much money their parents made, children in areas where water was fluoridated showed “significantly less cavities” than those in areas where water was not fluoridated.
In 2012, an Australian study analysed the data of every major study across the globe from 1990-2010. This encompassed 59 different studies in 10 different countries, with 83 different evaluations on the efficacy of fluoride treatment made. 30 of the evaluations covered primary teeth and the other 53 covered permanent teeth.
The smallest reduction of cavities was around 20% and the largest was around 60%. This is even more important when one realises that one cavity can cause a lifetime of gradually escalating treatment for one tooth.
