Smoking Triggers Big Changes in Mouth Bacteria, Study Finds
TUESDAY, March 29, 2016 (HealthDay News) -- Smoking can dramatically change the balance of bacterial species in the mouth, which may affect the risk of mouth, lung and digestive system diseases, a new study says.
The research also found that the proper mix of bacteria in the mouth is restored if people quit smoking.
Researchers analyzed the mix of about 600 bacterial species in the mouths (oral microbiome) of more than 1,200 Americans. All were 50 or older. The group included smokers, former smokers and people who never smoked.
Current smokers had significantly increased growth of more than 150 bacterial species, while 70 other species showed sharp decreases in growth. For example, Proteobacteria species accounted for less than 5 percent of overall bacteria in the mouths of smokers, compared with about 12 percent in nonsmokers, the researchers reported.Read entire article...
