Even if there are numbers of factor that causes gum disease; one of the common factor to cause it is the build up of plaque and tartar on teeth and along the gum margin. Know that plaque is a soft, sticky, colorless substances that is a combination of saliva, food particles and bacteria that accumulates on the teeth's surface and on the gums. By proper brushing at least twice a day and with daily flossing, one can get rid of bacterial plaque easily. When plaque is not eradicated, it can harden into calculus or tartar that firmly sticks on teeth causing bleeding and swollen gums. The only way to remove tartar is through a professional cleaning in the dentist's office with the procedure called scaling. The removal of tartar is crucial because this can be helpful in preventing early gum disease.
