Babies certainly need to have their mouths cleaned, and babies are defined as children from about 3-12 months of age. During this growth period, the child’s milk teeth have started to erupt gradually, so care must be taken to take care of oral hygiene. Even before the teeth erupt, parents can gently wipe the child’s gums with a soft gauze to remove milk stains and bacteria from the gums. After the baby teeth have erupted, it is also recommended to clean the baby teeth and the surrounding gums with gauze after each drink of milk. As the child approaches the age of 1 year old, he or she will have erupted 6-8 teeth and can consider using a soft baby toothbrush to brush the child’s teeth. However, it is important to note that you can brush your child’s teeth with warm water instead of toothpaste, so as to develop the habit of cleaning the mouth from a young age.
