I believe that we are no strangers to fluoride, fluoride can effectively prevent dental caries, but if the dosage is too much, it will cause fluorosis instead of affecting the development of the teeth, all children for the dosage of fluoride must consult a professional dentist. Should children brush their teeth with fluoride toothpaste or not? Whether children can use fluoride toothpaste has always been controversial, at present, our country does not have an authoritative body to give precise guidance, but the American Dental Association (ADA) has a clear guideline, summarized as follows, for your reference: children under the age of 3 years old, you should brush your children’s teeth immediately after tooth eruption and use fluoride toothpaste (but be sure to pay attention to control the amount of fluoride toothpaste, about the size of a grain of rice each time). (but be sure to control the amount of fluoride toothpaste, each time about the size of a grain of rice, about 0.1mg of fluoride, twice a day or as prescribed by the doctor), for children aged 3-6 years, each time about the size of a pea, about 0.25mg of fluoride, twice a day or as prescribed by the doctor, and in the process of brushing your child’s teeth to closely observe, to minimize the toothpaste swallowed. If parents are still unsure about the amount of toothpaste to use, they can consult a pediatric dentist to ensure that the fluoride is within safe limits! Suggestion: If parents are really worried about too much fluoride, for little ones under 3 years old, you can use a toothpaste that does not contain fluoride, but insist on brushing the teeth the right way (history article on how to brush your child’s teeth correctly), at least once a day in the morning and in the evening, and insist on flossing once a day. Also go to the dentist regularly for fluoride protective varnish (usually once every 3-6 months), thus reducing the chances of caries. After your child is 3 years old and is able to master swallowing well, you can use fluoride toothpaste, but make sure to control the dosage and prevent swallowing!
