What is recommended for fluoride application in children?

The recommendation for fluoride application in children is to begin as soon as permanent teeth erupt. This is crucial because the process of mineralization for teeth starts when they come into the mouth, making them more susceptible to cavities during this time. Fluoride is effective in enhancing the remineralization process of enamel, which helps to strengthen the teeth and prevent decay.

Starting fluoride treatments when permanent teeth emerge helps ensure that these critical years of development receive adequate protection against dental caries. It's important to provide fluoride during this period, as the risk of cavities can be higher when the new teeth are trying to establish themselves.

Given this context, applying fluoride only at the dentist's office may not be sufficient, as regular home care routines should include fluoride as well. Waiting until a child is 12 years old would be too late for the initial care needed for their permanent teeth. Additionally, delaying until a child has a full set of teeth misses the critical window of opportunity to protect the newly erupted teeth. Hence, initiating fluoride application immediately upon the eruption of permanent teeth is vital for promoting optimal dental health in children.
