OK..I have been vaping for 2 yrs now. Got me off cigs and I am glad, BUT...yes there it is...I HAVE had problems with my teeth hurting and gums bleeding...this coming from someone who has NEVER had a cavity in my life! I want to believe its NOT the vaping...but I am not sure! I take great care of my mouth, always have, like I said No CAVITIES EVER AND I AM 52. Makes me wonder and sad because I love vaping. Really no one else with those kind of problems???
