On Fluoride Day, celebrated each year on January 25th, we acknowledge the significant contribution fluoride makes in preserving dental health and warding off cavities. This global observance is dedicated to raising awareness about the importance of fluoride, where we can find it, how to consume it safely, and the possible issues that can arise from a lack of fluoride.

Beyond just promoting good oral health care habits, Fluoride Day also stresses the necessity for consistent dental visits.

History of Fluoride Day

Fluoride’s journey into toothpaste began in the early 20th century. Its importance in the prevention of tooth decay was first discovered in early 20th-century Colorado by Dr. Frederick McKay, who noticed a strange brown staining (known as “Colorado Brown Stain”) on many of the residents’ teeth. He also noticed that despite the staining, these individuals had remarkably low levels of tooth decay.

This led to a study conducted by McKay and Dr. Green Vardiman Black in the 1930s, who found that fluorosis (caused by exposure to high concentrations of fluoride), while providing discolouration, also resulted in a high resistance to dental caries (tooth decay).

Recognizing the potential benefits of fluoride in preventing tooth decay, the researchers conducted a series of tests in the mid-1940s in Grand Rapids, Michigan. They added fluoride to the public water system and observed the dental health of children born after fluoride was added. Results indicated a significant drop in tooth decay.

This revolutionary discovery led to the large-scale fluoridation of public water supplies and the introduction of fluoride in toothpaste.

Procter & Gamble’s Crest was one of the pioneers in this area. Released in 1955, it became the first toothpaste with clinical proof to claim it “reduced cavities”. The toothpaste was also the first product to be endorsed by the American Dental Association (ADA), the leading source of oral health-related information.

Fast-forward to today, most toothpastes now contain fluoride, and it continues to be a major contributing factor in the large decline in cavities worldwide since World War II.

7 Interesting Facts About Fluoride


Fluoride Discovery

The advantages of fluoride for dental health were unearthed in the early 1900s. Dentists found a link between reduced cavities and the consumption of water naturally laced with fluoride.


An Active Ingredient

Fluoride is more than just a component found in toothpaste - it plays the pivotal role. Its actions effectively safeguard your teeth.


Natural occurrence

Fluoride isn't an artificial substance crafted vying for dental health. Mother Nature herself provides it and it exists in substantial quantities in the environment and Earth's crust.


Enemy of Tooth Decay

What sets Fluoride apart is its potential to fortify the structure of the tooth, enabling it to withstand decay. This is achieved by fostering remineralization, a process in which lost minerals are replenished during the early stages of tooth decay.


Different Types of Fluoride

A variety of fluoride types are utilized in toothpaste - sodium fluoride, stannous fluoride, and monofluorophosphate, to name a few. Each has a unique way of defending your teeth and offering additional secondary benefits or potential drawbacks.


Fluoride in Drinking Water

In some places, fluoride is also infused into public water systems, a measure designed to boost dental health among the population. This initiative took off in America around the middle of the 20th century.


Too Much of a Good Thing

While fluoride has its benefits, excess consumption, especially in younger children, can result in dental fluorosis. This can manifest as white streaks or patches on the teeth.
