E-cigarettes just as bad for gums as regular smokes

A study has shown that when the vapours from an e-cigarette are burned, it causes cells to release inflammatory proteins, aggravating stress within cells.


Electronic cigarettes could be as harmful to gums and teeth as regular cigarettes, a new study suggests.

Various oral diseases

In laboratory experiments, researchers at the University of Rochester in New York exposed nonsmokers' gum tissue to e-cigarette vapours.

Their findings appear to counter arguments that the battery-operated devices are a healthier alternative to cigarette smoking.

"We showed that when the vapours from an e-cigarette are burned, it causes cells to release inflammatory proteins," said study leader Irfan Rahman. These, in turn, "aggravate stress within cells, resulting in damage that could lead to various oral diseases," explained Rahman, a professor of environmental medicine in the School of Medicine and Dentistry.

"How much and how often someone is smoking e-cigarettes will determine the extent of damage to the gums and oral cavity," Rahman added in a university news release.

The researchers also found that the flavouring chemicals used in e-cigarettes play a role in damaging cells in the mouth.

Potential dangers

"We learned that the flavourings – some more than others – made the damage to the cells even worse," said study co-author Fawad Javed.

"It's important to remember that e-cigarettes contain nicotine, which is known to contribute to gum disease," added Javed, a postdoctoral resident at the university's Institute for Oral Health.

More research, including long-term and comparative studies, are needed to better understand the health effects of e-cigarettes, said Rahman. He urged manufacturers to disclose all the materials and chemicals used in e-cigarettes to help consumers understand the potential dangers.

The study results were published recently in the journal Oncotarget.
