The second stage: from the age of two and a half years, parents should choose the toothbrush for the child to use at this age, twice a day in the morning and evening, standing behind the child, hands to teach the child to master the correct method of brushing teeth (brush method). Since children of this age have certain understanding and ability to express themselves, it is not difficult for them to master the correct way of brushing teeth as long as they are guided by parents with patience and guidance from shallow to deep.
