Many issues can cause bleeding gums. The most common is gum or periodontal disease. Almost half of all adults over the age of 30 have some form of periodontal disease. Increasing evidence suggests periodontal disease affects more than teeth and gums. Researchers have linked it to heart disease and other more serious conditions. People often do not have pain with bleeding gums.
The mildest form of periodontal disease is gingivitis, and it is common in adults. People with gingivitis may have red and swollen gums. The gums may bleed during brushing or flossing. In gingivitis, plaque accumulates along the gumline. Poor or improper brushing and flossing cause this plaque buildup. Bleeding gums due to gingivitis are reversible.
Periodontal disease can be slight, moderate, or advanced. Only slight periodontal disease, which is also called gingivitis, is completely reversible. Periodontal disease not only affects the teeth and gums but can also damage the bone. Periodontal disease is manageable, and symptoms like bleeding gums are treatable. Many people do not realize they have periodontal disease until it has advanced. The gums can bleed and pull away from the teeth, which loosen or fall out.
