I saw some "pink in the sink" and got all freaked out and thought that my mouth was on it's way to looking like the Crypt Keeper due to Vaping. I discovered that there's a vast amount of discussion/opinions about this online. Not being the poster child for Dental Health Weekly, I started doing a better job of brushing, flossing and rinsing. Being overdue for a cleaning, I saw my dentist who said there's nothing wrong with the integrity of my gums so quit worrying. So what's important for me is that I'm doing a better job of taking care of my teeth, my gums look a lot better and since I started Vaping my mouth doesn't smell like an ashtray.
