I started vaping about 2 months ago and just RECENTLY - in the past 2 weeks I've noticed that I am having problems with my teeth becoming extremely sensitive to everything I eat (especially sweets) and if I drink something cold or hot. I'm not sure if it's from ecigs or not. I have been using the same eliquids as always, about 24 nic and 100% PG. Now, I also did something different - I switched toothpastes. I began using Colgate Total within the last 2 weeks. So...now I'm not sure of the cause of this. Toothpaste or vaping?? I threw out that toothpaste and am using the Sensidyne and I guess if pain goes away I'll know the culprit. So the question I do have for others is has anyone else experienced overly sensitive teeth and gums from vaping? Help please! Thanks
