Fluoride toothpaste can prevent dental caries, which is a common sense of life. However, we have often heard voices of doubts about this common practice.

Therefore, some people would believe the statement, then they try to find an alternative product like fluoride-free toothpaste, which would keep them healthy.

Do we really need fluoride-free toothpaste?

Fluorine is one of the trace elements necessary for the physiological activities of the human body. It will affect the normal physiological functions of the human body if the intake is insufficient.

The normal progress of hematopoietic function, bone metabolism, the activity of nervous system enzymes, and so on. All are dependent on the presence of fluorine.

Fluoride also plays an effective role in protecting teeth. You can see the tooth anatomy image below.

Tooth Anatomy

About the tooth component, our tooth enamel’s main chemical is hydroxyapatite, the major ingredient of normal bone and teeth.

Hydroxyapatite makes up bone mineral and the matrix of teeth, which gives bones and teeth their rigidity.

The minerals inside our tooth enamel will dissolve and lose (demineralization), then it will regenerate and deposit on the tooth also (remineralization).

Demineralization and remineralization will maintain a balance generally, that keeps our teeth healthy. However, when demineralization always greater than remineralization, our dental caries will form.

Inside our tooth, hydroxide ions can replace by fluoride ions, which can produce fluorapatite. It’s stable and not easily corroded by acid, making remineralization greater than demineralization.

Moreover, in our tooth, the anti-plaque and anti-corrosion ability is enhanced too. Therefore, fluoride can prevent dental caries well.

To sum up, it is necessary to maintain a proper fluoride concentration in the oral cavity, and fluoride toothpaste is the most common method to achieve this effect.

Too much fluoride intake is harmful

For sure, fluorine is important to the human body and has a good effect on preventing dental caries, however, if overtaken will indeed cause harm and fluorosis.
