I was conflicted about whether to post this here or in the ejuice forum... Has anybody ever had an issue with sweet ejuice staining teeth? I am. It's not permanent. Fortunately, it brushes off but the first time it hapened, it gave me quite a scare. The offender is a sweet cheesecake/yogurt based max vg liquid. It's so damn good but it makes one tooth dark. My enamel is prone to staining on thst one tooth anyway. Makes me look like a true hillbilly. LOL. I can only figure the juice is creating soot when it gets heated up in the coil. I'm not buying any more because it makes me wonder if it's sooting up my lungs. It's a shame because I love a good sweet dessert juice.
