Bleeding Gums and Gingivitis: Causes, Vitamin C and Oral Care

Bleeding when you brush and red, swollen gums are warning signs you shouldn’t ignore · Most cases come from plaque and gum inflammation, but sometimes they are linked to low vitamin C · What causes it, how vitamin C fits in, and how to care for your mouth · This article sums up the evidence

Bleeding gums are mostly caused by gum inflammation (gingivitis) from plaque building up along the gumline · But vitamin C also plays an important role, because it is needed to make collagen, the structural framework of the gums and blood vessels · Severe vitamin C deficiency (scurvy) makes the gums bleed easily

1 Common causes

• Plaque/tartar — from not cleaning your teeth thoroughly
• Brushing too hard/using a hard brush
• Low vitamin C — fragile gums that bleed easily
• Smoking, hormones (pregnancy), diabetes

2 Caring for your mouth and gums

• Brush twice a day + floss — removes plaque
• Use a soft-bristled brush and brush gently
• Eat vegetables and fruit rich in vitamin C
• See a dentist/have a scale-and-clean regularly

⚠️ If bleeding is heavy, your gums are receding, your teeth feel loose or you have persistent bad breath, see a dentist

Are bleeding gums always caused by a lack of vitamin C? — Not always. Most cases come from plaque and gum inflammation, but vitamin C still matters for gum health
