"In college, we had to read about people shown pictures of gum disease. These were photographs of rotten gums and crooked, stained teeth, and the idea was to see how these images would affect the way people cared for their own teeth. One group was shown mouths only a little rotten. The second group was shown moderately rotten gums. The third group was shown horrible blackened mouths, the gums peeled down, soft and bleeding, the teeth turned brown or missing. The first study group, they took care of their teeth the same as they always had. The second group, they brushed and flossed a little more. The third group, they just gave up. They stopped brushing and flossing and just waited for their teeth to turn black."
