The most obvious sign that your baby is getting teeth is that he or she likes to bite things, often putting toys or fingers in the mouth to bite it. In order to relieve the discomfort of the gums, this time parents can massage the baby’s gums with gauze dipped in water to relieve this discomfort, and the baby will no longer bite the toy. Parents can also buy some sterilized toys for their children and let them bite them often to stimulate the development of the upper and lower jaws and make the eruption of teeth smoother. After the baby starts to grow teeth, parents should brush the child’s teeth, initially with a finger toothbrush, and gradually replace it with a child’s toothbrush. When your baby is under 3 years old, you can rinse his mouth with light salt water instead of toothpaste, and when the baby is over 3 years old, he can brush his teeth with children’s toothpaste when his milk teeth are fully grown.
