This is dangerous misinformation by Colgate

There's an advert that Colgate flights on YouTube , where a lady states that 90% of kids don't know how to brush teeth. This is dangerous misinformation, when was this study conducted, which areas were monitored?? And it's only black kids that she's talking about as they are the only kids depicted in this advert. Second to this Colgate's advet on an app that shows how people have yellow teeth, why is it only black people there?? Are you implying that only black people have yellow teeth??
