Gums bleed and hurt when brushing
Bleeding, sore gums often reflect plaque-related inflammation, but trauma, infection, gum disease, or medicines can also contribute.
The short answer
Bleeding and sore gums during brushing commonly indicate inflammation from plaque at the gum margin, but trauma, gum disease, infection, ulcers, and some medicines can also contribute. Gentle cleaning should continue while the cause is assessed.

How does plaque make sore gums bleed when touched?
Plaque bacteria can trigger inflammation in the gingiva, making it red, tender, and prone to bleeding when touched. A dentist or hygienist checks gum pockets, deposits, tooth surfaces, bite forces, and contributing medical or medication factors.
How should I clean painful gums while they are assessed?
Use a soft brush with gentle pressure twice daily and clean between teeth with floss or interdental brushes suited to the spaces. Do not stop cleaning the bleeding area, and arrange a professional examination if it does not settle.
When do sore, bleeding gums need prompt dental care?
Seek prompt care for facial swelling, pus, fever, loose teeth, severe pain, or bleeding that is difficult to control. Book an examination for repeated bleeding, persistent soreness, bad taste, or gum recession.
Are my gums inflamed or are periodontal pockets present?
Are the gums inflamed or are there periodontal pockets? Is there calculus, decay, trauma from brushing, or a medicine contributing? Which home-cleaning method fits my gum spaces?
