Introduction

Fluoride application for children refers to the topical use of fluoride on teeth during early tooth eruption, typically performed around age 3, and plays an active role in preventing dental caries. After fluoride application, the protective effect of fluoride on teeth is long-lasting, thoroughly penetrating the enamel and effectively safeguarding the teeth. Children should learn proper tooth-brushing techniques in daily life and schedule regular check-ups at the dental department of a reputable hospital.

After fluoride application, the protective effect of fluoride on teeth is long-lasting. It thoroughly penetrates the enamel and effectively protects all parts of the teeth. Applying high-concentration fluoride to the tooth surface forms a protective layer that enhances mineralization of the teeth, thereby reducing sensitivity, pain, and discomfort caused by external stimuli. During the procedure, the teeth requiring treatment are cleaned and fully exposed; once the tooth surfaces are dried, the prepared fluoride material is applied directly onto them. Fluoride application helps newly erupted teeth become stronger, prevents incomplete calcification, increases resistance to stimuli such as cold, heat, and acidity, and reduces tooth sensitivity. In cases where dental caries already exist, fluoride application promotes re-calcification of the affected areas and can aid in the repair of decayed teeth.

Children should learn proper tooth-brushing techniques in daily life, develop the good habit of rinsing their mouth after meals, and undergo regular dental check-ups at the dentistry department of a reputable medical facility.

Why shouldn't 2-year-old children receive fluoride application?

Applying fluoride can increase the teeth's resistance to acid and help reduce the risk of developing cavities. Fluoride application is generally not recommended for 2-year-old children, primarily because their young age often results in poor cooperation, increasing the risk of accidentally swallowing fluoride. Additionally, a 2-year-old's teeth may not have fully erupted; it is advisable to wait until the teeth have fully emerged before applying fluoride, thereby minimizing repeated procedures inside the mouth.

Which is better: pit and fissure sealants or fluoride application?

In general, both pit and fissure sealants and fluoride application are effective options. You can make an appropriate choice based on your individual circumstances and under medical guidance. It is recommended to visit a reputable hospital promptly and follow medical advice for proper treatment. In daily life, maintaining good hygiene habits—such as brushing teeth morning and night and avoiding smoking—is beneficial for dental health.
