Why was it important to study the relationship between tooth decay and fluoride in drinking water?
The study found that children who drank water with naturally high levels of fluoride had less tooth decay. 2 This discovery was important because during that time most children and adults in the United States were affected by tooth decay. Many suffered from toothaches and painful extractions—often losing permanent teeth, including molars, even as teenagers.
What are the benefits of fluoride?
Fluoride benefits children and adults throughout their lives. For children younger than age 8, fluoride helps strengthen the adult (permanent) teeth that are developing under the gums. For adults, drinking water with fluoride supports tooth enamel, keeping teeth strong and healthy. The health benefits of fluoride include having: 1 Fewer cavities. 2 Less severe cavities. 3 Less need for fillings and removing teeth. 4 Less pain and suffering because of tooth decay.
What is the process of testing water for fluoride?
This process of testing the water supply for fluoride and adjusting it to the right amount to prevent cavities is called community water fluoridation. Since 1945, hundreds of cities have started community water fluoridation and in 2016, nearly 73% of the United States served by community water systems had access to fluoridated water.
Where is fluoride made in an IMS system?
In the IMS system, the fluoride solution is made up in the saturator, as in conventional systems. But rather than being fed directly into the water supply, the solution overflows through a pipe into the secondary storage tank. The saturator tank allows solids to settle down while clear, saturated water flows into the secondary storage tank.
How does a fluoride feed system work?
The fluoride feed system is controlled by a single electrical panel re-wired at the factory. A single-phase, 110-volt power supply is provided to the system panel. Upon receiving power, the panel shows a green Power On light. At this point, all system components are ready to operate. When the external signal to start the metering pump is received, the metering pump starts drawing saturated fluoride solution from the storage tank and injecting it in the waterline.
How does a sodium fluoride saturator work?
Saturated sodium fluoride solution from the upflow saturator gently flows into the secondary storage tank through an overflow pipe. The storage tank is fitted with a low-level switch and a high-level switch. A metering pump draws saturated solution and injects it into the water line. The rate of solution feed can be controlled automatically by way of an external signal based on well pump flow rate. The metering pump can also be set to operate manually at a pre-set feed rate.
How is fluoride formed?
In traditional systems, the fluoride solution is formed by flooding a sodium fluoride bed with water in a saturator tank and then withdrawing the fluoride solution through a metering pump and injecting it at the destination point. The IMS system uses a secondary solution storage tank that effectively eliminates the chance of carryover of sodium fluoride solids from the saturator tank into the metering pump.
Can sodium fluoride be floating in a meter?
In older systems , you may well have lots of white sodium fluoride parti cles floating in the solution itself. This can lead to maintenance issues with the metering pump as the particles will enter the pump suction, despite the use of a strainer, and you have a less efficient operation.
Is fluoride solution free of sodium fluoride?
As a result, the fluoride solution is relatively free of sodium fluoride suspended solids. This reduces the chance of the pump plugging up, saving on maintenance and related downtime. In general, a treatment plant will experience a more efficient fluoride addition process.

What is the history of fluoride in drinking water?
In the 1930s, scientists observed a reduction in tooth decay among children who drank water with naturally occurring fluoride. In 1945, the community of Grand Rapids, Mich. was the first to formally add fluoride to its city water system. Over time hundreds of other cities added fluoride, and by 2014 fluoridated water was flowing through nearly 75% of community water systems, according to the CDC.

How to test for fluoride in water?
How is continuous testing and auditing conducted to ensure safe levels of fluoride products are in my drinking water? 1 The manufacturing process is documented by an NSF auditor at the initial audit of the manufacturing site and during each subsequent, annual unannounced audit of the facility. 2 The manufacturing process, ingredients and potential contaminants are reviewed annually, and the product is tested for any potential contaminants of interest. 3 Minimum testing for all fluoridation products includes heavy metals of toxicological concern and radionuclides because they may be contained in phosphate ore. 4 NSF also inspects samples and tests and certifies products at rail transfer and storage depots where fluoridation products are transported in bulk via tanker trucks and rail cars before delivery to water treatment plants.
Why is fluoride important for teeth?
Fluoride helps to remineralize tooth surfaces and prevents cavities from forming.
