Gum bleeding from fire is considered as periodontitis. When local inflammation is aggravated by fire, the gums will be swollen and congested, causing gum bleeding when encountering stimulation or brushing or biting hard objects, which requires periodontal treatment in hospital. Gum inflammation due to localized plaque and calculus stimulation requires scaling to remove the calculus and then medication. Some heavier cases of periodontitis also require surgical treatment and good brushing in normal life. So bleeding gums due to fire is due to local inflammation caused by fire, and local gums tend to bleed when there is obvious inflammation, and there is no other powerful disease. However, some bleeding gums are not necessarily caused by fire, but may be caused by a blood disorder of its own that leads to bleeding gums.
