Question
A parent inquires whether their 5-year-old son is old enough to begin brushing his teeth.
Answer
According to professional advice, children should learn to gargle by the time they are 20 months old, and as they grow older, they should gradually learn the proper technique for brushing. Tooth decay is one of the most common dental issues in children, with its incidence rising year by year. Therefore, preventing early childhood permanent tooth decay starts with protecting the primary teeth. Parents should change their perception of primary tooth care and recognize that the health of primary teeth is crucial for the development of permanent teeth. Cultivating good oral hygiene habits in children is the fundamental method for preventing dental diseases.
