XYLITOL 

This is the logo for Lotte Xylitol gum. Xylitol gum was designed by Taku Sato and has been a long-selling product since 1997. The red star in the middle indicates "brilliance," while the white and gray circle that is the figure indicates cleanliness. The logo also has a visual appearance that looks like back teeth if you try to look at it from a peek-a-boo perspective from above.
