Smoking Changes The Bacteria Living Inside Your Mouth

The composition of the oral microbiome significantly changes every time you smoke, based on a research posted this month within the International Society for Microbial Ecology Journal. Although more study will become necessary to be able to establish a concrete connection between this effect and the development of smoking-related diseases, data shows that their vulnerability could be increased by modifications towards the microbial communities in smokers’ mouths towards cigarette smoke’s poisonous consequences.

To perform this study, researchers in the NYU Langone Medical Center took mouthwash products from a group of 1,204 individuals, comprised of previous and present smokers, in addition to non-smokers. To be able to decide the frequency of the different microorganisms contained in the mouths of the participants, they examined the microbial genetics in these samples.

In doing this, they unearthed that the oral microbiome of existing smokers differed significantly from that of non-smokers and previous smokers, noting that cigarettes appear to promote the growth of over 150 different bacterial species while inhibiting the proliferation of a further 70. Nevertheless, the very fact that there’s no distinction discovered between people who’d never adopted the routine and the samples of former smokers suggests that this effect is not permanent, and can be reversed by giving up smoking.

Shockingly, several bacterial species of the phylum Proteobacteria were discovered to become dramatically decreased in the mouths of the smokers. These microbes are recognized to perform a vital part in wearing down most of the poisonous aspects of tobacco smoke, such as aromatic hydrocarbon. As a result, a lack of these microorganisms will probably have damaging effects for smokers’ health.

Alternatively, microorganisms of the phylum Streptococcus were found to become more populous in the mouths of smoker than that of non-smokers. These microorganisms have been related to a heightened threat of periodontal problems, meaning that cigarettes can lead to the development of gum disease.

The cause for this interruption towards the oral microbiome has a number of possible explanations. For example, as tobacco smoke reduces the availability of oxygen inside the mouth, a breeding ground that favours bacteria over microorganisms is created by it. Considering the fact that several Streptococcus species are anaerobes while Proteobacteria are generally aerobic, this concept appears to be plausible.
