I brush 3 times a day, and floss once a day. Ive been noticing that my dental floss in one pocket will have blood on the dental floss, not really bleed but just have blood on the string. And sometimes I will hit it again and then no blood on the floss. Then last tight I noticed a very faint red streak when I spit into the sink. Just an almost trace amount of blood. Less than 1/4 of a droplet of what apeared to be blood. Again my teeth dont usually bleed. Is this a problem I read that its not a problem unless my gums actively bleed even after brushing and flossing. And then I read that your gums should not bleed at all?
