Smoking kills bacteria the mouth and creates conditions for growth of pathogenic flora. That is why smokers are often faced with periodontal disease, tooth decay and other dental diseases.
Researchers from new York analyzed the bacterial composition of the oral cavity of smokers and non-smokers. Were found differences in growth of individual microorganisms. In the mouth of smokers was 2.5 times less proteobacteria. They help the body in removing certain toxins.
Reducing the number of beneficial bacteria creates conditions for growth of pathogenic flora, e.g. Streptococcus. These bacteria most often cause destruction of tooth enamel.
Moreover, disturbed intestinal microflora of the oral cavity can lead to the development of cancer, says a publication of the International Society for Microbial Ecology.
