My cousin had this same problem. What worked for her was TeaTree Oil(Essential Oil) and also "Mercurius Sol". It is commonly referred to as "Merc Sol". Google it and find lots of homeopathic info. She swears by it.
I'm told they can be excruciatingly painful.
Good luck....
I have tried tea tree oil. I could get past the smell if it helped. I have heard of a lot of people having success with it though. I'm glad it helped your cousin. I'm all for natural remedies, but homeopathics is an area I've avoided and will continue to do so. It's a load of... (This is coming from someone who worked in the nutritional
supplement industry for 6 years)
The only thing I can think of is switching your toothpaste. Make sure whatever you're using doesn't contain ska (sodium laurel sulfate - sp). That ingredient has been associated with canker sores.
Yep. SLS is widely discussed. I really wish it was as simple as that. I must have tried every SLS free toothpaste in existence, including straight baking soda and hydrogen peroxide.

Hopefully it is just from quitting and not a recurrance of your prior troubles ! (ouch !)
Lots of good info in there. It has been less than two weeks since I quit smoking, so it's (way) to early to call this one yet, but I hope you're right.
Since the OP had the sores BEFORE he started vaping and they disappeared when he smoked, I don't see any relation to vaping. I also don't think we have any evidence that nicotine is the problem when people have allergic reactions to PG or VG. I don't think the nicotine is the issue in any of these cases but rather just the PG or VG or the ingredients used for flavorings.
I don't think so either. I hope no one came to the conclusion that I'm blaming vaping. I apologize if I came across that way. This was definitely a pre-existing issue.
Google search to bring up previous canker sore threads on this forum (search for this in Google):

There are a bunch of threads.
I don't know why I didn't search the thread before posting this.

For some reason I was thinking my situation was unique. It obviously isn't. I apologize.
According to my immunologist: Smoking suppresses the immune system. When you quit smoking, your immune system can over-react by sending autoantibodies out to attack tissue. Hopefully your body will learn to correct itself, but it's possible that your mouth will be more sensitive to changes now (including foods, toothpastes, etc.).
After researching this for quite a bit today, this makes a lot of sense. I have allergies to other things including food, but I have learned to avoid them. I've never related a specific allergy to cankers, but it might be more simple that. Allergies are nothing more than your immune system over reacting to a harmless "foreign invader". It seems very likely that my own immune system is the cause of the cankers. If they continue beyond a couple months I will definitely be bringing this up with my doc.
Cankers as painful as they may be are not going to kill me. I refuse to continue to destroy my body by smoking simply to avoid cankers.
Thanks again everyone for all your insights.
