It is reported that thanks to fluoride, the dental health of children and adolescents has improved significantly due to its importance in preventing tooth decay . Small amounts of fluoride make “tooth enamel” more resistant to decay bacteria, especially in places where the brush cannot reach. However, does fluoride really protect teeth from decay?  

Before answering this question, we will get acquainted with what the German website “MSN” said. The site said: Every person has a hole or two in their teeth, mostly due to neglect of dental hygiene and excessive consumption of sweets. Because bacteria in the mouth absorb sugar from food and turn it into acids.

The body, for its part, tries to eliminate these acids and releases minerals, especially calcium and phosphorus, from the “tooth enamel” and settle in saliva. Experts call this purification “demineralization.” The minerals concentrated in the saliva then transfer back to the “tooth enamel” for protection.

Here comes the role of toothpaste, especially fluoride, which protects the teeth from the risk of decay. According to current guidelines, for bodies active in the protection of teeth from caries, the use of fluoride-containing preparations is one of the most important pillars of caries prevention, according to the German “Life Goose On” website. Even the decrease in tooth decay in children and teenagers today is primarily attributable to the increased use of fluoride, according to a report of the German Dental Association.

Fluoride works in different ways: On the one hand, it promotes remineralization and thus incorporation of calcium phosphate into tooth enamel more quickly, giving the acids less time to attack the teeth. On the other hand, fluoride is stored in tooth enamel and can be used immediately when necessary.

In addition to the fluoride-rich toothpaste, it covers the teeth with a very thin protective film. It works primarily to neutralize acids in the mouth and prevent other minerals from fading from the enamel. However, you should pay attention and not overuse of fluoride.

The site advises those with permanent teeth that the  best thing to do in the morning and evening is to use a fluoride toothpaste  that contains less than 1,000 parts per million of fluoride – that is, one milligram per gram of toothpaste. If the body contains large amounts of fluoride over a long period of time, it can lead to chronic fluorosis, which is accompanied by yellow-brown spots or streaks on tooth enamel and bone damage.
