Impress your dentist at your next checkup by getting your daily dose of vitamin D.

In a study, people with the highest blood levels of vitamin D were 20 percent less likely to suffer from bleeding gums during an oral exam, compared to people who had the lowest blood levels. Vitamin D has anti-inflammatory properties that help reduce gum irritation. Get your D from salmon, enriched dairy products, or a supplement.

Vitamin D is vital for maintaining healthy bones and a strong immune system. Now a new study suggests vitamin D may have anti-inflammatory properties that combat gingivitis, a painful condition characterized by sore, irritated gums that bleed during brushing, flossing, and oral exams. In addition to getting enough D, brush and floss regularly and get your teeth professionally cleaned every 6 months to reduce the risk of gingivitis and cavities. Ask your dentist or hygienist to recommend an anti-plaque mouth rinse as well.
