Consumer News-Secondhand smoke and gum disease
It’s been clear for years that smokers have a higher risk of gum disease but now there’s research showing secondhand smoke can also increase the risk.
Researchers at the University of North Carolina-Chapel Hill, using data from another study that included 2,379 nonsmokers ages 53-74, have concluded that exposure to secondhand tobacco smoke for a few hours each day can double a person’s risk of gum disease. People exposed to secondhand smoke less than 25 hours each week had a 29 percent increased chance and for those exposed more than 26 hours, the odds were twice as high.
The study appears in the December issue of the American Journal of Public Health.
