Most effective way to get rid of gum disease like gingivitis and removing sore bleeding gums?

Dental visit: The most effective way would be to have the condition treated by your dentist or periodontist. Either one would do a comprehensive periodontal checkup and then advise you how they will proceed with treatment.

Brush and floss: Periodontal (gum) disease can be controlled with proper brushing and flossing. The bacterial waste and deposits must be professionally removed before the gums will begin to heal.

See a gum specialist: If your good habits at home, i.e. Brushing and flossing, don't reduce the problem, you may have more serious periodontitis rather than just gingivitis. See your dentist soon.
