Vitamine C. also known as ascorbic acid, is an essential nutrient found mainly in fruits and vegetables. It is water soluble, meaning that it must be consistently replenished as the body eliminates any leftover amounts. The body requires vitamine c for wound healing, as well as to form and maintain bones, blood vessels, skin, tendons, cartilage and ligaments. While the recommended daily allowance of vitamine c is 60 mg/day or about the amount in one orange, some research seems to indicate larger amounts are beneficial. One study shows that individuals who consume only the recommended daily allowance are one and one half times more likely to develop periodontal disease than people who consume 180 mg/day, or three times the recommended daily amount of vitamine c. Although diet plays an important role in overall well being and oral health, you need to keep in mind that suppliments do not cure periodontal disease. Good home care (brushing and flossing daily) as well as regular dental visits are needed to ensure oral health.
