Experts in oral health and dentistry have revealed increasing damage linked to the use of e-cigarettes, a relatively new phenomenon in the world of smoking.

Studies show that the harm caused by these devices is not limited to the lungs and respiratory system but extends to the mouth and teeth, causing issues such as dry mouth, tooth decay, gum inflammation, and enamel erosion.

Research also warns that the various flavors added to e-cigarette liquids may increase the severity of these damages, especially among young regular users.

Dr. Smita Mehra, a dentist at Neem Tree clinics in London and Surrey, says, “E-cigarettes are more addictive than tobacco for many young people and harm oral health alarmingly.”

Her clinics have observed an increase in early gum inflammation and plaque buildup among young people, problems that were rare before the spread of vaping.

E-cigarette liquids contain substances like “propylene glycol” and “vegetable glycerin,” which cause dry mouth and plaque accumulation. Nicotine reduces saliva secretion, while the hot vapor increases dryness, weakening the mouth’s natural ability to clean itself.

Dr. Mehra explains, “Saliva is the mouth’s natural defense; without it, bacteria accumulate, mouth acidity increases, and decay accelerates, especially near the gum line and between teeth.”

Doctors confirm that dry mouth caused by vaping can lead to gum inflammation, bleeding, and long-term tooth loss.

James Golnick, a dentist and founder of Bow Lane Dental clinic in London, points out that vaping particularly affects the front teeth, which are directly exposed to the smoke, leading to enamel erosion, stains, and decay.

Flavors and Their Impact on Dietary Habits and Oral Health

Studies warn that sweet flavors in e-cigarette liquids may encourage the consumption of more sugary foods harmful to teeth, in addition to altering the balance of microbes in the mouth, increasing the risk of gum disease.

A study published in the journal mSystems indicates that long-term e-cigarette users develop oral microbes associated with gum bleeding and bone loss.

Dentists emphasize that e-cigarettes are not safe, especially for non-smokers and young people. Richard Holliday, Professor of Restorative Dentistry at Newcastle University, says, “There is increasing evidence that e-cigarette users are at risk of tooth decay, and this issue must be taken seriously.”

A 2024 study conducted by University College London and the University of Innsbruck confirms that e-cigarette users show DNA changes in cheek cells similar to those caused by traditional smoking.

Experts stress that although vaping is less harmful than traditional smoking for smokers, it is not safe for non-smokers, especially youth. They warn that damages may appear late, making treatment difficult or impossible, as tooth enamel does not regenerate.
