People with poor gum health 'smile less'

The health of an individual's gums can affect how often they smile, a new study has revealed.

Published in the Journal of Periodontology, the research found that the higher the level of periodontal - or gum - disease a person has, the more likely they are to limit how widely they smile and cover their hand with their mouth.

The study highlighted how smiling is one of the most universally recognisable way of communicating.

"Smiling plays a significant and essential role in overall wellbeing," said study author Dr Marita R Inglehart. "Previous findings suggest that smiling can affect social interactions, self-confidence and can influence how people perceive one another."

Dr Inglehart added that the research had systematically proven that gum health is linked to smiling behaviour.
