Overview

• Dental clinicians report increases in cavities, gum inflammation and enamel wear in younger patients who vape regularly.
• Propylene glycol, vegetable glycerin, nicotine and warm vapour reduce saliva and promote sticky plaque, raising decay risk.
• A 2025 study in JDR Clinical & Translational Research found vapers were 80% more likely to have dry mouth than non-users.
• Youth use remains notable, with 7% of 11–17-year-olds vaping and about one in five having tried it, according to YouGov for ASH.
• Researchers and public-health experts advocate measures to curb youth appeal, with UCL findings showing standardized packaging and limited flavour descriptions reduce attractiveness.
