What Deficiency Causes Bleeding Gums? A Clay Road Houston Guide

If your gums bleed and you are doing everything right at the brush and floss, you might wonder whether something is missing from your diet. Patients across Northwest Houston ask our Clay Road team this question.

Short Answer
Two vitamin deficiencies are linked to bleeding gums: vitamin C deficiency, which causes scurvy, and vitamin K deficiency. Both appear on MedlinePlus's list of causes. Plaque and gingivitis are still more common, so a dental exam comes first, and a blood test can confirm a deficiency.
Key Takeaways
- Low vitamin C (scurvy) and low vitamin K are both linked to bleeding gums.
- Plaque and gingivitis are common causes too, so do not assume it is your diet.
- Only a medical test can confirm a deficiency.
- Take supplements if you have been diagnosed with a deficiency, as MedlinePlus advises.
- A dentist can rule out gum disease first.
Vitamin C and scurvy
MedlinePlus lists scurvy, which is caused by a vitamin C deficiency, as a cause of bleeding gums.
Vitamin K
Vitamin K deficiency is also on the MedlinePlus list. Vitamin K matters for blood clotting, which is why it appears next to blood thinners as a cause.
Do not skip the dental side
Our team sees plaque and tartar, gingivitis, and periodontitis far more often. If you take vitamins but leave plaque in place, the bleeding is likely to continue. Our page on bleeding gums treatment covers the full list of causes.
What MedlinePlus recommends
- Visit the dentist at least once every 6 months for plaque removal.
- Brush gently with a soft bristle toothbrush at least twice a day.
- If you have been diagnosed with a vitamin deficiency, take vitamin supplements.
- Do not use tobacco, since it makes bleeding gums worse.
