Usually we can train our children to brush their teeth in stages. The first stage: the baby will grow his first tooth from about 6 months, that is, he will "brush his teeth". Of course, there is no toothbrush here, but the parents wrap the index finger with clean gauze and dip it in water to help the baby clean his mouth and wash away the attachments on his teeth and gums. This oral care method usually lasts until the child is two and a half years old, when all the deciduous teeth in the mouth erupt. The second stage: from the age of two and a half, parents should choose a toothbrush for children of this age, stand behind their children twice a day in the morning and evening, and teach their children the correct brushing method (brushing method) by hand.
