I don't mean to dig up an old thread, but wanted to comment on this as well. I stopped smoking analogs [and started vaping] a few days after my 30th birthday, which was March 2009. I had smoked for 15 years (with a year and a half break from smoking in the early 2000's) anywhere between 1/2 pack on up to 2 packs a day. I had never had any cavity's which I attributed to aggressive fluoride treatments, not eating candy, not chewing gum, and brushing my teeth consistently 2x a day. I did have gum swelling which my dentist said was from smoking, but it was never bad.
I had a cleaning the beginning, 2009 and came back still no cavities, with x-rays taken as usual. Quit analog cigs and started vaping the beginning of April 2009. My next cleaning was September 2009 which is when I found out I had my first cavity! Nothing in my habits had changed other then quitting smoking analogs and starting vaping. I chalked it up to getting old and never considered vaping as the cause. Unlike the OP, I rarely get dry mouth, even when vaping heavily for many hours. I don't like VG as it burns my throat, so I exclusively use PG. Anyway, the cavity was small, but I had it filled immediately and also added a fluoride mouthwash to my teeth cleaning regiment.
Fast forward to this past March 2010 checkup where the dentist said I now another cavity! WTF! He was shocked and said he had never seen someone with perfect teeth like mine suddenly go downhill so fast. Again, the cavity was small, but the x-rays don't lie, it was there clear as day. I swear to you, as I did to him that I have not done anything differently then I had done in the past in fact as stated above, I was even more aggressive with my teeth care. I had it filled, which sucked as I refuse to get the silver fillings and had to once again pay extra for the natural color. There is no way in hell I want to see anything other then white on my teeth. Anyway, the dentist said he would be also watching two other teeth as it looks like they have deep grooves that may be forming cavities as well!
Fast forward again to today. As I type this post I feel like those two teeth he was talking about do in fact have cavities. I do not have pain, but a dull annoyance and can see clearly the deep grooves he was talking about are slightly dark in color. If I stick a pick in them they are "sticky" which is a sure sign of a cavity. If this is the case, that would make FOUR cavities in a little over a years time, after not having a single one for 30 years.
I no longer have any doubt that vaping has to be attributing something to the tooth decay. My only guess is its the glycerin as I had been smoking analogs for years and the nicotine, tar, and other crap never caused anything other then gum swelling.
Now I have a choice. I refuse to start smoking again, so its quit vaping or deal with dental problems. I love vaping and do not want to stop but this cavity thing is getting out of hand. I am not sure if switching to VG and dealing with the sore throat will help the issue or worsen the issue. I guess there is a possibility that switching to 0mg nicotine could help, but I don't think its the nicotine thats causing the problem as analogs had nicotine and only irritated my gums, never causing cavities in the past. Again, the only variable I can come up with here is glycerin.
Sigh... no idea how to handle things, but knowing how much I love vaping I am sure I will be paying for more fillings in the future. I guess fillings are better then dying a horrible death from cancer.
