Smoking can cause various oral problems. Smokers are known to have a high risk of developing cancer of the mouth, throat and esophagus. And cigarettes can also cause dental and periodontal disease, including gum (gum) disease. Cigarette smoke can alter the bacteria (microbiome) in your mouth, making existing periodontal problems worse.
Not much information is available on the medical side effects of e-cigarettes on oral health. A recent literature review in the Journal of Oral Pathology and Medicine summed up the state of the science, noting the "lack of evidence". However, the authors summarize some interesting findings.
The authors describe a small study that suggested a possible increase in the incidence of nicotine stomatitis (which, oddly enough, is not caused by nicotine), a heat-induced condition that produces lesions in the mouth . This is a secondary condition that usually resolves itself when the heat source (usually a pipe) is removed.
A small pilot study investigated the oral microbiome of 10 smokers and 10 non-smokers. The study found that the bacterial profile in the mouths of respondents who used e-cigarettes was similar to the non-smoking control group, but the oral bacterial profile of the smoking group was very different. The researchers concluded that the vapor did not alter the microbiome. Again, this study was too small to draw strong conclusions.
Finally, there is a problem that the explosiveness of the electronic cigarette causes damage to the user's mouth. While very few users have had catastrophic accidents resulting in severe face and mouth tears and broken teeth, it's more like a battery safety issue. Using modern adjustment equipment and high-quality batteries, the atomizer is almost impossible to damage the user's teeth from the mold.
