When did dentists start using fluoride?
When did dentists start using fluoride?
1901
Fluoride was first added to drinking water in Grand Rapids, Michigan in 1945, just a decade or so after scientists first identified its teeth-saving properties. In 1901, a dentist named Dr. Fredrick McKay moved to Colorado Springs and noticed what the area’s residents called “Colorado brown stain” on patients’ teeth.
What is the history of fluoride?
Fluoride research had its beginnings in 1901, when a young dental school graduate named Frederick McKay left the East Coast to open a dental practice in Colorado Springs, Colorado. When he arrived, McKay was astounded to find scores of Colorado Springs natives with grotesque brown stains on their teeth.
Where does fluoride originate from?
Fluoride is created when salts from the element fluorine combine with minerals in soil or rocks. Due to its simple origins, fluoride is found naturally in soil, water and many foods. It also occurs naturally in the human body in bones and teeth.
What was the original purpose of fluoride?
Early in the 20th century, dentists discovered that fluoride reduced the number of cavities in their patients’ teeth. Soon, amidst much debate and rancor, fluoride was regularly added to American public drinking water supplies.
Who founded fluoride?
Like many of the medicines we have today, fluoride was stumbled upon by chance. The discovery of fluoride’s applications in dentistry trace back to the early 1900s when Frederick McKay, a dentist, noticed that many Colorado natives (~90% in one town) had significant brown staining on their teeth.
When was fluoride added to water in the UK?
1964
Community water fluoridation schemes have operated for more than 70 years; the first scheme was introduced in the US in 1945. The first substantive UK scheme was established in Birmingham in 1964.
How is fluoride created?
This fluoride is derived from natural calcium deposits in phosphate rock and then purified. These materials are also used to create a number of products that people use every day, such as cosmetics, ceramics, animal food, and soil fertilizer.
Can fluoride be manufactured?
Fluoride can also be synthesized in a laboratory. Calcium Fluoride is the primary compound found in natural water sources. Sodium Fluorosilicate or Fluorocilicic Acid are the most commonly used compounds in municipal water supplies, as they are readily available and less expensive to manufacture.
Is fluoride good for teeth?
Fluoride helps prevent tooth decay by making the tooth more resistant to acid attacks from plaque bacteria and sugars in the mouth. It also reverses early decay.
Where did the idea of fluoride come from?
Fluoride research had its beginnings in 1901, when a young dental school graduate named Frederick McKay left the East Coast to open a dental practice in Colorado Springs, Colorado.
How did the discovery of fluoride change dentistry?
It started as an observation, that soon took the shape of an idea. It ended, five decades later, as a scientific revolution that shot dentistry into the forefront of preventive medicine. This is the story of how dental science discovered-and ultimately proved to the world-that fluoride, a mineral found in rocks and soil, prevents tooth decay.
Who was the head of the National Institute of Dental Hygiene?
The architect of these first fluoride studies was Dr. H. Trendley Dean, head of the Dental Hygiene Unit at the National Institute of Health (NIH). Dean began investigating the epidemiology of fluorosis in 1931. One of his primary research concerns was determining how high fluoride levels could be in drinking water before fluorosis occurred.
Is there a link between fluoride and enamel fluorosis?
Namely, fluoride levels of up to 1.0 ppm in drinking water did not cause enamel fluorosis in most people and only mild enamel fluorosis in a small percentage of people. This finding sent Dean’s thoughts spiraling in a new direction.
