E-cigarettes can cause tooth damage, two food science lecturers from Cardiff Metropolitan University's School of Sport and Health Sciences said in a statement in the British Dental Journal. This research has now been shown to be fraught with errors.

Newcastle University vaping and dental experts Richard Holliday, Elaine McColl, Anthony Weke and Zella Sayeed published a letter in the British Dental Journal debunking Cardiff's claims.

The four wrote that they were disappointed to see several fundamental errors and misrepresentations, and went on to correct five major errors in the paper on the eroding potential of e-cigarettes.

Experts in Newcastle said the study authors cited a World Health Organization poster and falsely claimed that nicotine was associated with a high risk of oral and systemic health complications.

In fact, nicotine has been used in the form of NRT for more than 30 years, including in pregnant women, and according to Scoop, nicotine is considered very safe even with long-term use.

Equally important, the authors falsely claim that e-cigarettes are associated with cancer. The supporting references do not make this claim, but point out that there is no long-term evidence associated with oral and systemic health effects.

Newcastle experts then pointed UK dental professionals to well-thought-out public health guidelines, which essentially concluded that for the best chance of quitting, supportive and drug therapy should be used, and that e-cigarettes could be part of the regimen.

Nancy Loucas, executive coordinator of the Coalition of Tobacco Harm Reduction Advocates in the Asia-Pacific Region (CAPHRA), said the biggest mistake food science lecturers make is one made by so many people - talking about WHO as the official public The organization's anti-vaping stance health position.

"It's clear that all UK public bodies, including the NHS, are ignoring WHO advice. They support vaping because they know they don't erode teeth and don't cause gum disease," Loucas said. "Scientific and human evidence has once again triumphed over another untenable ideological lie about e-cigarettes."
