I started vaping in the middle of September last year, a month after my biannual cleaning and annual dental x-rays... in November I started vaping strictly VG as it just seemed more natural and healthy from what little reading I did on the matter. Yesterday I had this years annual dental x-rays, I have 3 cavities between my teeth, I hadn't had 3 cavities in my entire life, and never any between my teeth! I'm thinking that it has to be the vaping as it's the ONLY change I've made in the past year, my brushing and flossing habits are the same, as is my diet and as I have since middle school I only drink sugar free beverages. My dentist was as surprised as I was... it wasn't till a few hours later that I made the possible vaping connection. I'm devastated... sure cavities are better than cancer but I guess I was hoping there really were no real vaping side effects. My dentist prescribed some toothpaste with extra fluoride that is supposed to prevent future cavities so hopefully with it and the knowledge of the VG, glucose connection I'll have no further problems.
