How Water Fluoridation Helps Oral Health

Research has proven fluoride to be a safe, beneficial agent in our water. States with fluoride in their drinking water lead to communities with better oral health. Water containing fluoride keeps a low level of fluoride in the mouth all day, thereby reducing tooth decay. It also helps to strengthen enamel and the overall development of adult teeth.

Cavities, or tooth decay, are often caused by a breakdown of tooth enamel from acids produced by bacteria found in plaque and along the gum line. Eating and drinking foods high in carbohydrates can encourage bacteria’s production of acid and erode your teeth. Preventing cavities can cause less of an expense and allow families to save money.

Mineral fluoride occurs naturally from the earth. Released from rocks into the soil, water, and air, all water already contains some amount of fluoride. Some ground water and natural spring water tend have high amounts of fluoride. However, there are amounts in water that may not be enough to prevent cavities. Because of water fluoridation, U.S. oral health is much better today than it was years ago.

In the 1930s, most children and adults in the US experienced more toothaches and painful extractions that would cause them to lose their permanent teeth at an early age. Scientists then began to study the relationship between tooth decay and fluoride levels in drinking water. By 1945, Michigan was the first state to test the water supply and add the right amount of fluoride to its water system. The CDC named this as one of the great achievements of the 20th century.

Michigan’s method of prevention is now known as community water fluoridation—a system that makes fluoride accessible to families of all classes. Today, at least 75% of the US population have water systems with enough fluoride to protect their teeth, but there are also approximately 100 million Americans who are unable to access drinking water with fluoride. Along with drinking water, you can use a toothpaste or a mouthwash with fluoride in it. If your water lacks fluoride, you can also ask your dentist about providing supplements for you and your family.

Overall, drinking fluoride leads to stronger teeth with fewer chances of cavities. A community with water fluoridation experience fewer cavities, fewer fillings, are less likely to suffer from tooth decay, and are more likely to save money for families and their health care system.
