Many people who notice bleeding gums assume they lack vitamin C. In fact the more common cause is plaque and gum inflammation.
- Vitamin C helps make collagen for the gums, but a severe shortage is rare.
- Bleeding gums are usually caused by plaque, tartar and gum inflammation.
- A balanced diet of fruit, vegetables, calcium and protein is enough for most people.
- Bleeding that lasts more than two weeks is a reason to see a dentist.
Vitamin C is needed to make collagen, which keeps gums and the small blood vessels in the mouth healthy. A severe and long lasting shortage of vitamin C can make gums swollen and quick to bleed. However, a deficiency that serious is quite rare in people who eat normally, so bleeding gums usually have another cause.
More common causes of bleeding gums
- Plaque and tartar building up and inflaming the gums, see what bleeding gums mean.
- Brushing too hard or using a hard bristled toothbrush.
- Untreated gingivitis or gum disease, see what gum inflammation is.
- Some general illnesses or medicines that affect blood clotting.
What to eat for healthy gums
- Leafy greens, bell peppers, citrus fruit, kiwi, guava and strawberries provide vitamin C.
- Calcium rich foods such as yoghurt, milk and small fish eaten with their bones.
- Enough protein from fish, eggs and beans helps keep gum tissue healthy.
- Drink enough water so the mouth is less dry.
A balanced diet is enough for most people. You should not take high dose supplements on your own to treat bleeding gums without a doctor's advice.
When should you see a dentist?
- Gums bleed for more than two weeks even though you brush gently.
- The gums are swollen, red and sore, there is a bad smell or teeth feel loose.
- Bleeding is heavy, hard to stop or comes with other unusual signs elsewhere in the body.
