RED TOOTHPASTE

I saw an ad in a newspaper maybe a month ago that read 'Bleeding gums when you brush your teeth? YOU MAY HAVE GUM DISEASE'. Of course it was for a mouthwash that cures it, or prevents it, whatever. So I start to notice the colour of the toothpaste I spit out in the evening - pink. Not red, no definite BLOOD, but pink. I guess that if your gums are bleeding a little, the toothpaste goes pink. A lot, red. I don't know whether my flatmates have gum disease, but that same stuff from the newspaper ad sits on the shelf in the bathroom. I heard it turns your teeth brown - didn't use it since I didn't want gum disease AND brown teeth. Then I get to looking at the toothpaste, BEFORE it goes in my mouth. Pink.
