[The use of fluorides is one of the most important areas of dental prevention. It has many beneficial effects on teeth, and it is worth using them starting from childhood. It has an important role in caries prevention and in ensuring the strength of the enamel. However, we must pay attention to take fluoride into our body in moderation. If we don’t act accordingly, we can damage the condition of the teeth and the structure of the bones, to which we should pay special attention during childhood. Fluorosis can be prevented by attention, but adequate information is essential for this, which can be provided by both dentists and dental hygienists.]
