Good news for people who are concerned about their gum health: vitamins C and D are thought to improve and prevent gum disease.
There is a well-known link between gum disease and vitamin C deficiency, as people with low vitamin C intake levels are thought to have higher rates of gum disease. This vitamin is thought to help because it is used to accelerate the regeneration of bone and to repair connective tissues.
Vitamin D is thought to have anti-inflammatory properties that can reduce your chances of developing gum disease. Studies have found that people with high vitamin D levels in their blood were less likely to notice bleeding gums and other symptoms. Sun exposure is one of the best possible sources of this vitamin, and supplements are also available.
