"Design a modern, professional Meta ad image for a web developer offering custom website services for dentists in the USA. The image should feature a sleek dental clinic background with subtle medical elements, such as dental tools or smiling patients, blended into the design. In the foreground, show a clean, beautiful website mockup on a desktop and mobile phone screen, emphasizing responsive design and functionality. Use soft blue and white tones, reflecting a clean, clinical aesthetic. Add subtle accents of green to signify growth and trust. Include a prominent call-to-action button that says 'Get Your Custom Dental Website!' with a subheading that highlights 'Attract More Patients with a Stunning Website.' Make sure the overall vibe is modern, clean, and professional."
