Study: Some e-cigarette liquids may increase caries risk

Some sweet flavors in e-cigarette liquids may increase the risk of dental caries, according to research supported by the ADA Foundation and published in September in PLOS One.

For the study, researchers evaluated e-cigarette aerosols in flavors including pineapple and cotton candy and found that some have similar physio-chemical properties as sugary gelatinous candy and acidic drinks, which interact with hard tissues of the oral cavity in a way that can adversely affect teeth.

“This is an important finding that suggests the complexity of e-cigarettes on human health goes beyond respiratory and cardiac systems and may have significant implications on oral health,” researchers concluded in the article. “It is a common perception among e-cigarette users that vaping is less harmful or is without health risk. Though it is acknowledged here that e-cigarette aerosols contain less harmful and potentially harmful constituents compared to combustible tobacco products, the data suggests e-cigarettes produce viscous aerosols that change surface characteristics and have biological consequences.”
