We learned last year how stress can affect your oral health. Necrotizing ulcerative gingivitis- or NUG- also has the nickname "trench mouth" because it was common in WWII among highly stressed soldiers fighting in the trenches.
Presumably there is a link between periodontal disease and stress and a good reason for it, mediated through the body's inflammatory response.
