Fluoride — Communist Conspiracy or Tooth Saver?

When fluoride first came into the public consciousness as it was being added to municipal water supplies in the 1940s and 50s. Research that had started around the turn of the century was showing real promise with fluoride in the prevention of dental cavities. By the 30s, levels in drinking water were being tested to find the right amounts for prevention without causing fluorosis (staining caused by high levels of fluoride).

In 1945, Grand Rapids, Michigan became the first city in the world to fluoridate its drinking water. This became a study that was followed the world over. Originally planned to last 15 years, after only 11 years the fluoridation was deemed an overwhelming success — the rate of children who had developed cavities had dropped by 60%!

Today, fluoride is everywhere. You’ll find it in most toothpastes, mouthwashes, and other dental products. You’ll find it in most municipal water supplies (it occurs in water naturally and it is also added by most cities). Fluoride is a proven ally in the fight against dental decay.

Still, you’ll occasionally hear some crazed fringe group talk about taking fluoride out of the water and other products because it’s a government conspiracy to control our minds. Uh, right. Those people advocating such nonsense probably need fluoride’s benefits more than anyone!

Since our team at Gentle Dental likes our patients to know as much as possible about dental hygiene, here is some background info on fluoride that you may not have known.


What is fluoride and how does it protect the teeth?

Your mouth every day is like a mine, with minerals coming and going. Minerals are added to and lost from a tooth’s enamel layer through two processes, demineralization and remineralization. Demineralization is the problem. Minerals are lost from a tooth’s enamel layer when acids, formed from the bacteria in plaque and sugars in the mouth, attack the enamel. Fortunately, when you eat foods and drink water, minerals such as fluoride, calcium, and phosphate remineralize the teeth. Therein lies the ongoing battle — too much demineralization without remineralization results in tooth decay.


Fluoride is a mineral that occurs naturally in many foods and water. It helps prevent tooth decay by making the tooth enamel more resistant to those acids from bacteria and sugars in the mouth. Fluoride also has the cool effect of reversing early cases of decay. For kids under 6, fluoride becomes incorporated into the development of permanent teeth. This makes the teeth resistant to the assault of acids to demineralize the teeth. Fluoride also speeds remineralization and disrupts acid production in the mouth.


When is fluoride the most beneficial?

It was thought that only children benefit from fluoride, but new research shows that topical fluoride from toothpastes, mouth rinses, and fluoride treatments are important to help adult teeth fight decay. For children, it’s long been known that children between 6 months and 16 years need fluoride to help build their teeth.
