Fluoride application is known as one of the treatments for preventing tooth decay.
This is a common preventive treatment in pediatric dentistry, but how does it help prevent tooth decay?
Also, is it not effective for adults?
We will start by explaining the function of fluoride and an overview of what it is.

First of all, what is fluoride?

First, let's start with the basics: what is fluoride?
Fluorine is an element and exists in the world mostly by combining with something else.
What we see and use are fluorine compounds.
In other words, elemental fluorine does not exist.

Fluorine compounds themselves are known to be mineral components of rocks and soil.
It is also found in seafood and agricultural products.
When you think about it, we are unknowingly taking in fluoride through our daily diet.

Why is fluoride effective in preventing tooth decay?

Next, let's take a look at why fluoride application is effective in preventing tooth decay.
Broadly speaking, there are two types of preventive dental effects that fluoride provides.

Effects on teeth

Fluoride has the effect of strengthening tooth structure (making teeth less susceptible to cavities).
This is because when fluoride is applied to teeth, a stable crystalline structure called fluoroapatite is created. In addition, it also works to absorb calcium and phosphate contained in saliva into the teeth and promote remineralization. In the case of early stage cavities, there are many cases where this alone will heal the cavities naturally.

Effects on the oral environment

The cavities hidden within plaque produce enzymes.
This causes acid to be produced, which dissolves the teeth, which is the main mechanism of tooth decay. Fluoride has the ability to prevent this enzyme from producing acid (antioxidant effect). In addition, fluoride itself has antibacterial properties, so it also suppresses the activity of tooth decay bacteria.

Fluoride application prevents tooth decay in both children and adults

Now, when it comes to fluoride application, many people probably think of it as something that children do, right?
It is true that the enamel that covers newly grown baby teeth is very thin and soft, making them susceptible to cavities. For this reason, applying fluoride to children is a very effective preventative method, with the aim of "strengthening the tooth structure early."
However, as mentioned in the previous section, fluoride is effective in preventing tooth decay regardless of age.
There are benefits for adults as well, so be sure to get treatment at a dental clinic.

Summary

By the way, preventing tooth decay using fluoride is not just a treatment at a dental clinic.
Fluoride toothpaste and fluoride mouthwash, which can be used at home, are also sold at drugstores.
Take this opportunity to use fluoride for your oral self-care.
