The International Society for Microbial Ecology recently reported on a study done on the oral microbiomes of cigarette smokers as compared to non-smokers.

Results indicate that smoking significantly changes the oral microbe mixture.

Over 1200 adults were involved in the ongoing study, which is sponsored by the New York University Langone Center and the Laura and Isaac Perlmutter Cancer Center.

Results indicate that nearly 150 species of bacteria were distinctly higher in smoker’s mouths, and further 70 species were significantly lower.

Streptococcus bacteria was found to be 10% more abundant in the mouths of smokers. Striptococcus is a known cause of tooth decay.

Researchers did have some good news for smokers, however; quitting smoking will return their mouth’s microbiome back to normal in about six months.
