Generate an oral cleaning technology poster that does not require the product itself. The background features a soft space from light ice blue to white, with abstract white tooth curves at the bottom. Centered at the top are the subheading "Oxygen Clean Technology" and the main title "Dismantling Toothstains." The title uses a fresh modern sans-serif line, with the main title dark blue and slightly bold. In the center of the image, an enlarged transparent hydrogel bubble serves as the visual focal point, with blue-and-white active microbeads and delicate water glow inside the bubble; A smaller bubble is placed underneath, showing that the particles gradually disperse around the sediment. On the right side, from top to bottom, three pieces of information are connected by fine gray-blue threads: 01 "Deeply softens / Gently acts on tooth surface attachments," 02 "Removes residue / Cleans everyday oral stains," 03 "Freshness protection / helps maintain a clean feeling." The serial number is large and light, the label uses a slender cyan blue block, and the main text is dark gray. Overall, it is lightweight, clean, and highly scientific; Avoid dental diseases, medical treatment commitments, original brands, parameter footnotes, watermarks, and screenshot margins.
