Developing good oral hygiene habits starts with children. And in the opinion of experts, many parents are not doing a good job in this regard. Many parents think their children are too young to let their toddlers bathe themselves, but dare to let them brush their own teeth. In fact, it is very difficult for children to brush their own teeth because of the fine hand movements that are still to be developed and the lack of proper guidance. Many children eat snacks and drink drinks indiscriminately all day long, and these bad habits can cause serious tooth decay. Did you know? The earlier the prevention of tooth decay and other oral problems, the better. Experts give parents the following advice: 1. Remember to clean your baby’s gums with soft gauze after each feeding; don’t fill the bottle with milk or juice and then let your child sleep with the bottle in his mouth. Be sure not to dip the pacifier into honey or other syrup for the child because the child likes it, cariogenic bacteria are highly infectious and can be easily transmitted to the child through the spoon or pacifier, so don’t let the elderly or nanny share the baby’s tableware or kiss the baby’s lips. 2. Don’t let your child eat snacks indiscriminately all day long – even the healthiest snacks can leave enough food residue in the mouth to feed cariogenic bacteria. If you want to give your child a snack, you should choose fruit or other unprocessed foods, not bags of junk food, and gummi candy, dried fruit and other sticky things like dried fruit. 3. Fruit juice (even organic juice), because of its very high sugar content, is as dangerous a drink for teeth as carbonated drinks. Try to use water instead. 4. Before the age of 3, brush your child’s teeth twice a day with a rice-sized fluoride toothpaste, after the age of 3 you can change to a pea-sized toothpaste. At the same time, you need to use the plaque detection method to make sure that your child can actually brush independently before you let him/her operate on his/her own. Even if the child starts to do it by himself/herself, the parents need to make sure that he/she is brushing cleanly every day and not to let him/her go. 5.Brushing before the age of 7 should be done by the child himself, and then the parents should brush the child again seriously. 6.After the child grows two adjacent teeth, it is time to start flossing to clean the gap between teeth.
