I've heard the "smoke" from vaping includes heavy metals and chemicals that have been linked to popcorn lung, but does vaping hurt your teeth, tongue or gums? Does it stain your teeth like regular cigarettes would?
Vaping is harmful to the gums and can cause periodontal disease because of the nicotine ingested. Nicotine is a vasoconstrictor and decreases blood flow which leads to decrease in nutrients and oxygen to the gums. This also affects the ability for the body to fight off bacteria and heal. Vaping may stain teeth less than regular cigarettes but still comes with harmful side effects. Its best to avoid doing both!
