Bleeding of gums occurs due to deficiency of
Bleeding gums are most often linked to plaque-related gum inflammation, not a single deficiency, though nutrition and medical conditions can contribute.
The short answer
Gums commonly bleed when plaque irritates the gingival margin and causes gingivitis. Nutritional deficiencies, medicines, hormonal changes, blood disorders, and poorly fitting dental work can also contribute and need clinical assessment.

What is the direct answer?
What does this question mean?
Plaque bacteria trigger inflammation in the gingiva, making it red, swollen, and prone to bleeding. Vitamin C deficiency can affect gum tissues, while iron, folate, or vitamin deficiencies may be considered with other symptoms rather than assumed from bleeding alone.
What can you do next?
Brush gently twice daily with a soft brush, clean between teeth, and arrange a professional examination instead of stopping because of bleeding. Tell the dentist about diet, medicines, pregnancy, bruising, and medical conditions.
When should you seek dental care?
Seek prompt care for spontaneous heavy bleeding, widespread bruising, marked swelling, fever, loose teeth, or bleeding that continues despite gentle pressure. Persistent bleeding also warrants assessment for periodontal disease.
What should you ask the dentist?
Ask whether plaque, calculus, gum pockets, a medicine, diet, or a medical condition is contributing. Ask whether cleaning, blood tests, a change in medicine, or periodontal treatment is needed.
