I Brush My Teeth Every Day, Twice A Day With

I brush my teeth every day, twice a day with an electronic toothbrush but I still have bleeding gums it's not all over but in certain areas such as my left top sharp tooth (I've have the other removed due to having a dental brace put in) the four front lower teeth. The more problematic of the four is the second on the right from the middle where my tooth is slightly buckled. I try to get into every part of my teeth but I can have days where the blood turns my white tooth paste a crimson red
