Let's see if they Astroturf this out of the forum. vaping has built up a rubbery film on my teeth. It is like the VG glycerine is hardening. It is hard to get rid of it. I spoke to a retail vape vendor today (he does not want his name used) who said, yes, his dentist told him this happens. Anyone else? I'm seeing my dentist asap. It the feeling of almost having your teeth shrink wrapped in plastic. Awful.
