The Most Common Cause:
Bleeding gums are most often caused by harmful plaque – and the millions of bacteria in it – found at or around the gum line being left to develop gingivitis. Gingivitis, a mild form of gum disease, may require treatment and improved oral hygiene to help eliminate it. If left untreated, bleeding gums and gingivitis can lead to a more serious form of gum disease called periodontitis.
Other Causes:
If you don’t have gingivitis, but still suffer from bleeding gums, don’t ignore the problem. Bleeding gums can also be caused by bleeding disorders, leukemia, vitamin K deficiency, hormonal changes, scurvy or the use of blood thinners. If you notice bleeding from your gums, it’s best to consult with your dentist or doctor to determine the cause.
