Adding vitamin C in diet can help cure bleeding gums, finds study

Washington: A new study explores added advantages of Vitamin C consumption and advocates that adding it to our daily diet could work wonders in healing bleeding gums. If your gums bleed, make sure you are brushing and flossing twice a day because it could be a sign of gingivitis, an early stage of periodontal disease. 

However, you should also check your intake of vitamin C, as per the study. The findings of the study led by the University of Washington, were published in the journal ‘Nutrition Reviews’.

"When you see your gums bleed, the first thing you should think about is not, I should brush more. You should try to figure out why your gums are bleeding. And vitamin C deficiency is one possible reason," said the study's lead author Philippe Hujoel, a practicing dentist and professor of oral health sciences in the UW School of Dentistry.

Hujoel’s study analysed published studies of 15 clinical trials in six countries, involving 1,140 predominantly healthy participants, and data from 8,210 U.S. residents surveyed in the Centers for Disease Control and Prevention’s Health and Nutrition Examination Survey.

The results showed that bleeding of the gums on gentle probing, or gingival bleeding tendency, and also bleeding in the eye, or retinal hemorrhaging, were associated with low vitamin C levels in the bloodstream. And, the researchers found that increasing the daily intake of vitamin C in those people with low vitamin C plasma levels helped to reverse these bleeding issues.

Of potential relevance, said Hujoel, who is also an adjunct professor of epidemiology in the UW School of Public Health, both a gum bleeding tendency and retinal bleeding could be a sign of general trouble in one’s microvascular system, of a microvascular bleeding tendency in the brain, heart, and kidneys. 

The study does not imply that successful reversing of an increased gingival bleeding tendency with vitamin C will prevent strokes or other serious health outcomes, Hujoel stresses. However, the results do suggest that vitamin C recommendations designed primarily to protect against scurvy, a deadly disease caused by extremely low vitamin C levels, are too low and that such a low vitamin C intake can lead to a bleeding tendency, which should not be treated with dental floss.

Consequently, Hujoel does recommend people attempt to keep an eye on their vitamin C intake through the incorporation of non-processed foods such as kale, peppers, or kiwis into your diet, and if you can’t find palatable foods rich in vitamin C to consider a supplement of about 100 to 200 milligrams a day.

If someone is on a specialised diet, such as a paleo diet, it's important that they take a look at their vitamin C intake, Hujoel said. "Vitamin C-rich fruits such as kiwis or oranges are rich in sugar and thus typically eliminated from a low-carb diet."

This avoidance may lead to a vitamin C intake that is too low and is associated with an increased bleeding tendency. People who exclusively eat lean meats and avoid offal, the vitamin-rich organ meats, may be at particularly high risk for a low vitamin C intake. The association between gum bleeding and vitamin C levels was recognized more than 30 years ago. In fact, two studies co-authored by the former dean of the UW School of Dentistry Paul Robertson (published in 1986 and 1991) identified gum bleeding as a biological marker for vitamin C levels. However, this connection somehow got lost in dental conversations around bleeding gums. 

“There was a time in the past when gingival bleeding was more generally considered to be a potential marker for a lack of vitamin C. But over time, that's been drowned out or marginalized by this over-attention to treating the symptom of bleeding with brushing or flossing, rather than treating the cause," Hujoel said.

Hujoel’s literature review also determined that "retinal hemorrhaging and cerebral strokes are associated with increased gingival bleeding tendency, and that (vitamin C) supplementation reverses the retinal bleeding associated with low (vitamin C) plasma levels."

So, missing the possible connection between gum bleeding and low levels of vitamin C has the potential to have serious health consequences.The study authors wrote, "A default prescription of oral hygiene and other periodontal interventions to `treat` microvascular pathologies, even if partially effective in reversing gingival bleeding as suggested in this meta-analysis.

"A default prescription of oral hygiene and other periodontal interventions to `treat` microvascular pathologies, even if partially effective in reversing gingival bleeding as suggested in this meta-analysis, is risky because it does not address any potential morbidity and mortality associated with the systemic microvascular-related pathologies," they added.
