A growing body of dental research is revealing a disturbing new health risk associated with electronic cigarettes, moving the focus beyond lung damage to a rapid and severe form of tooth decay. Dentists across multiple countries are reporting cases of long-term vapers, some in their twenties and thirties, presenting with unexpectedly aggressive cavities that appear to bore directly into the tooth enamel, sometimes described by patients as sudden 'black holes'. This phenomenon, distinct from the gradual decay typical of poor oral hygiene, is prompting urgent warnings from oral health professionals about a potential epidemic of vaping-related dental disease. The mechanism behind this accelerated decay is believed to be multifactorial. E-cigarette aerosol, while containing fewer traditional carcinogens than cigarette smoke, is far from inert. It typically consists of a base of propylene glycol and vegetable glycerin. When heated and inhaled, these substances create a sticky, sugary film on tooth surfaces. Critically, this film is highly adept at trapping the bacteria naturally present in the mouth. The resulting environment acts as a supercharged fuel source for bacterial acid production, which relentlessly attacks tooth enamel. Unlike occasional sugar consumption, the near-constant exposure from frequent vaping provides bacteria with a continuous feast, leading to unremitting acid erosion. Compounding this problem is the effect of vaping on oral dryness. Both propylene glycol and nicotine, a common ingredient in many e-liquids, are known to reduce saliva flow. Saliva is the mouth's primary defense system, neutralizing acids, washing away food particles, and aiding in remineralization—the process of repairing early tooth damage. By creating a persistently dry oral environment, vaping cripples this natural protective mechanism, leaving teeth uniquely vulnerable to the acid assault. This combination of constant bacterial feeding and a disabled defense system creates a perfect storm for catastrophic decay. The clinical presentation is alarming dentists. "We are seeing cavities in unusual places, like the front teeth and the smooth surfaces of molars, which are...
