What is Fluoride?

Fluoride occurs naturally in most water supplies, and may be added to municipal water by injection of hydrofluorosilicic acid, sodium silicofluoride, or sodium fluoride into the water. Fluoride is an additive to water to promote strong teeth and prevent cavities. Fluoride compounds are also involved in the production of aluminum, steel, uranium, cement, enamel, and plastics. Fluoride levels can source from erosion of natural deposits, fertilizer runoff, or from discharge from factories.

Fluoride Exposure and Health Risks

Fluoride in small concentrations can be very beneficial to protect against tooth decay. It also stimulates bone formation. However, large concentrations of fluoride can cause skeletal fluorosis, bone disease characterized by tenderness and pain of bones, and mottled teeth. Elevated concentration of fluoride can also cause tooth discoloration. Fluoride can inhibit various enzyme systems and erythrocyte glycolysis, which causes anticoagulation. Higher doses of fluoride can irritate the stomach and cause ulcers.

Measuring Fluoride

Dissolved fluoride concentration in water can be measured in units of parts per million (ppm). We carry kits from CHEMetrics that determine fluoride levels in water from 0-3.00 ppm and monitors from ATI that detect fluoride levels. The monitors have digital communication capabilities to ensure easy measuring and monitoring. All of our fluoride products can be viewed HERE.
