Do you spit blood when you brush your teeth? Spitting blood when you brush your teeth needs to be treated seriously as it can be one of the first signs of gum disease, a major cause of tooth loss. Corsodyl toothpaste is specially formulated for people who spit blood when they brush. Bleeding gums can be caused by the build up of plaque bacteria along the gum line. If not removed, this can cause inflammation and if left untreated can eventually cause the gum to recede and ultimately, the tooth to fall out. Taste improvement over time: Most people liked its unique taste after 14 days of using Corsodyl toothpaste.
