Generate a fluoride toothpaste formula principle poster without the product itself. The background is pure light gray-white, with two lines of coarse black modern sans-serif lined on the top left: "Fluoride Protection Formula / Protect Daily Cleanliness," and two gray-black lines below say "Gently cleanses the tooth surface, helps maintain oral freshness." In the lower half of the painting, an enlarged white tooth is placed, with the crown surface covered by a translucent light blue condensation protective layer, with the condensate edges smooth and natural; A small number of transparent blue circular particles float around it, with abstract letter symbols representing mineral elements.
The teeth use a soft, realistic 3D material, with a protective layer that has a fine mesh glossy texture but does not appear medical. The title occupies the upper half with blank space, the teeth are slightly larger in the center of the lower half, making the information concise and without stacked cards. Avoid diseases treatment, absolute moth-proofing, original image copy, specific ingredient dosages, small footnotes, watermarks, and screenshot borders.
