Orange Stained Teeth - Orange tooth stains typically occur near the gum line and are caused by the presence of chromogenic (photographic) bacteria or food buildup. Children are especially prone to orange tooth stains, usually as a result of improper or infrequent brushing.
If vaping were the cause of any staining, the staining would be over all of the tooth, much like coffee or red wine. Way too many times NORMAL hygiene, or lack thereof, are the cause of our problems... and sadly, vaping is often considered the root of the cause... because vaping is "evil"... sad... very sad...
