Prompt:

A cute and friendly cartoon style illustration of a slightly closed mouth for a children's teeth-brushing game background. The view is from the front, showing the tongue, upper and lower teeth, which should occupy approximately 2/3 of a 1920x1080 screen. Include a subtle glimpse of the nose above the mouth and the cheeks on the sides. Use bright, soft pastel colors. The teeth should be clearly defined and appear tappable for touch screen interaction. --ar 16:9 --s 750
