A simple, bold white smile shape on a red background.

The ad opens with a red background and a white curved smile shape. Text appears: "Sorrir é um ato de cuidado" (Smiling is an act of care). The scene transitions to close-ups of people smiling: a woman laughing, a mother holding a baby, a young girl, and a group of children and adults in a classroom setting. A teacher or presenter is demonstrating brushing teeth on a large model of teeth. The Colgate logo is visible in the top left corner of most scenes. The final scene shows the Colgate logo with text about being the most recommended brand by dentists.
