A new study indicates that low levels of vitamin C in the bloodstream may be an underlying cause of bleeding gums. Researchers say brushing and flossing might not be enough to reverse this oral health issue.
When gums bleed, it is often a symptom of underlying oral health issues, such as gingivitis or periodontal disease, an inflammatory condition that affects gum tissue and teeth.
In the early stages of gingivitis, gums may swell and bleed. If left untreated, these symptoms can worsen, causing the gums to pull away from the teeth, resulting in tooth and bone loss.
Traditional treatments for bleeding gums include adding more brushing and flossing to the daily oral hygiene regimen and treating underlying conditions that may contribute to the development of gingivitis.
Disorders linked to an increased risk of gingivitis include diabetes and immune deficiencies. Lifestyle choices, such as smoking, may also play a role.
However, new research found that, although brushing and flossing are critical for overall oral health, lack of adequate vitamin C, also known as ascorbic acid, may be an underlying cause of bleeding gums.
Researchers from the University of Washington, WA, recently published their results in the journal Nutrition Reviews. Study authors reviewed data from 15 clinical trials in six countries, with 1,140 mostly healthy participants.
They also analyzed National Health and Nutrition Examination Survey data from 8,210 individuals in the United States who had experienced some degree of eye-related hemorrhaging or bleeding.
The researchers found that participants with low levels of vitamin C in their bloodstream were more likely to have gums that bled upon gentle probing, the tendency for bleeding gums, and a higher rate of bleeding in the eye known as retinal hemorrhaging.
Interestingly, the study authors found that increasing vitamin C intake in participants with low vitamin C plasma levels helped stop their gums from bleeding and reversed eye-related bleeding issues.
Prof. Philippe Hujoel, the study’s lead author and adjunct professor of oral health sciences at the University of Washington School of Dentistry, says the study results are significant because the tendency for bleeding gums and retinal hemorrhaging could indicate an issue with the microvascular system.
This system encompasses the tiny blood vessels in the body, including the brain, heart, and kidneys.
