She explained that the mouth with the yellow teeth is actually healthier because the gums were a pale shade or pink, while the white bright smile was surrounded by red, inflamed gums - indicating disease.
'If you brush properly in a way to interrupt plaque formation, your gums will have a light pink hue on the junction where the gum and the teeth meet (same for flossing between teeth), which is a good sign of health, no inflammation,' she said.
'During the inflammatory process of the gum area(s) affected, blood rushes to the areas and causes a red coloration of the gum. This inflammation is called gingivitis.
Lowering blood pressure could prevent Alzheimer's disease, according to new research.
A study of more than 9,000 over 50s found those who got it below the newly recommended level - with a top reading under 120 - slashed their risk of memory problems by about a fifth.
They were also a sixth (15%) less likely to develop dementia, a figure that may be conservative to the short duration of the trial.
Dr Maria Carrillo, chief science officer at the Alzheimer's Association, said: 'Proof that lowering blood pressure can lower risk for dementia may be key to improving the lives of millions of people around the world.'
