The video starts with a close-up of a dirty tooth with a large cavity. A boy and a girl are standing next to it, and the boy is holding a toothbrush. The girl is wearing a yellow dress and a pink headscarf, while the boy is wearing a green shirt and brown pants. The boy starts brushing the tooth, and the girl watches him. Suddenly, a group of green and red germs appears inside the cavity. The boy continues to brush the tooth, and the germs disappear, leaving the tooth clean and white. The girl looks happy and smiles.
