The introduction of Fluoride in everyday drinking water was first introduced in 1951. The U.S. Centers for Disease Control listed water fluoridation as one of the ten great public health achievements of the 20th century. Introduction of Fluoride in our drinking water has had a direct correlation with the reduction of tooth decay. A 1994 World Health Organization expert committee suggested a level of fluoride from 0.5 to 1.0 mg/L (milligrams per litre). Bottled water typically has unknown fluoride levels, and some domestic water filters remove some or all fluoride. With more households these days using bottled and filtered water, there has been a decline in the amount of Fluoride the average person receives. It is, therefore, recommended that Fluoride treatment be provided to patients at their regular dental check-ups. For patients who are at a high risk of cavities, the Village Dental team may recommend toothpaste with higher fluoride concentrations for home use.
