The short answer
Gums most often bleed because plaque irritates the gingival margin and causes gingivitis. Brushing trauma, gum disease, hormonal changes, medicines, and some medical conditions can also contribute.
What is plaque doing where teeth meet the gums?
Plaque is a sticky bacterial film that collects where teeth meet the gums. If it remains, the gingiva becomes red, swollen, and more prone to bleeding during brushing or interdental cleaning.
How can you clean your teeth when gums bleed?
Use a soft brush with gentle short strokes and clean between teeth daily. Do not stop cleaning because of light bleeding, but arrange an examination if it does not improve as plaque is removed.
When should recurring gum bleeding be assessed?
See a dentist for recurrent bleeding, gum recession, loose teeth, persistent bad breath, or bleeding without contact. Mention easy bruising, nosebleeds, and all medicines to the clinician.
What should you ask about gingivitis or periodontitis?
Ask whether you have gingivitis or periodontitis. Ask whether professional calculus removal, a changed cleaning method, or medical evaluation is needed.
