water fluoridation desreases dental decay
Use of fluorides is of importance for the control and prevention of dental caries in both children and adults. The ingestion of fluoride results in its incorporation into the dentin and enamel of unerupted teeth; this makes the teeth more resistant to acid attack after eruption into the oral cavity as the tooth structure contains increased concentrations of fluorohydroxyapatite, which is more resistant to future attack by acids.
Water fluoridation provides protection to primary teeth against dental caries but to somewhat lesser degree then permanent teeth. Caries reduction benefits to primary teeth ranged between 40% and 50%, whereas the range for permanent teeth was between 50% and 60%, which persists throughout the lifetime of the person. 56% decrease in the prevalence of root-surface caries in adults who lived in continually fluoridated community was observed.
Till now no adverse affects of water fluoridation has been reported even after its use for the past 30-50 years. So dont worry..........go ahead and drink.....
