Blood Disorders
Blood disorders can contribute to sore gums in two ways: the blood itself and the blood vessels. When a person has a blood disorder, their body may not be able to clot efficiently or at all, which means that even minor cuts can lead to excessive bleeding. Sometimes, this bleeding is internal, beneath the skin, or in another body part. This is called an internal bleed. Internal bleeding can sometimes cause soreness in the gums, resulting in other symptoms like fatigue, dizziness, and fainting.
People who have blood clotting disorders will have trouble stopping bleeding when they have gum sore. This is especially true if they have hemophilia, which causes them not to produce enough of a protein called factor VIII, which is involved in blood clotting. If people with hemophilia don’t get the treatment they need, they can develop a brain bleed. This happens when blood leaks into areas of the brain, causing problems with thinking and memory.
