Three stages of teaching children to brush their teeth: The first stage: when the baby starts to grow the first tooth, that is, from about six months onwards to give the baby “brush teeth”. Of course, the brushing mentioned here does not use a toothbrush, but the parents use clean gauze wrapped around their index finger dip clean water to help the baby clean the mouth, wash away the teeth and dental bed on the attachment, this oral care method generally to last for two and a half years old, when all the milk teeth in the mouth erupted. The second stage: from the age of two and a half years, parents should choose the toothbrush for children of this age, twice a day in the morning and evening, standing behind the child, hands to teach children to master the correct method of brushing teeth (brush method). Because children of this age have certain understanding and ability to express themselves, as long as the parents follow the instructions, from the shallow to the deep patient guidance, I believe it is not difficult for children to master the correct method of brushing teeth. The third stage: from the age of three, children have been through half a year of transition training, should be able to complete the brushing action independently. But at this time, children are still very naughty, lack of initiative and self-consciousness, parents usually have to play a supervisory guidance role, so that children develop good oral hygiene habits, so that children have a healthy and beautiful teeth.
