A - Gums that bleed are caused by inflamed or irritated gum tissue. Gum diseases and other infections, trauma, and ill-fitting dental appliances are all possible causes of bleeding gums. Other reasons are seen as poor oral hygiene, tobacco use, certain medications, and pregnancy.
Bleeding gums are a common problem. Sometimes this may occur while flossing, brushing, or using a toothpick to remove food particles between teeth. This one would heal soon, but if it doesn't, then you should see your dentist as soon as possible.
