What is the appropriate age for children to start using fluoride toothpaste?

Fluoride toothpaste is not recommended for infants under 1 year of age. Children aged 1–3 can begin using fluoride toothpaste, while children aged 3–6 should use it properly and under supervision. Children over 6 years old can use fluoride toothpaste in a manner similar to adults, though parental guidance is still necessary.

Infants under 1 year old have either not yet fully erupted teeth or only just begun teething. Their oral mucosa is delicate, and their swallowing reflex is not yet fully developed. Using fluoride toothpaste may lead to excessive fluoride intake. At this stage, it is recommended to clean the mouth by gently wiping the tooth surfaces and gums with sterile gauze dampened with warm water.

Children aged 1–3 have partially erupted primary teeth and can start using fluoride toothpaste to prevent cavities. The amount used should be carefully controlled, and parents should assist with brushing throughout. After brushing, ensure the child's mouth is cleaned promptly to avoid swallowing residual toothpaste. For children aged 3–6, most primary teeth have typically erupted. Parents should continue supervising the brushing process and teach children how to spit out toothpaste foam to minimize swallowing. Additionally, choose fluoride toothpaste specifically formulated for children, as its fluoride concentration meets children’s oral needs—adult fluoride toothpaste should be avoided.

Children over 6 years old have gradually matured swallowing function and can independently use fluoride toothpaste. A pea-sized amount is sufficient. Parents should remind them to brush for at least two minutes, ensuring all tooth surfaces are thoroughly cleaned, thereby helping prevent cavities and maintain good oral health.
