A tooth shaped like an orange, questioning if healthy food can be bad for teeth.

The ad opens with a close-up of a tooth shaped like an orange, with a green stem at the top. The image is slightly blurred, suggesting movement. As the video progresses, a section of the orange tooth is revealed to show the inner layers, symbolizing enamel erosion. Text appears on the right side of the screen, explaining the concept. The orange tooth then transforms into a clean, white tooth, enclosed in a turquoise shield-like shape. The final scene displays three boxes of Sensodyne Proschmelz toothpaste and a slice of orange, with text emphasizing protection and strength.
