I checked other.
It was kind of a domino effect with me.
I was noticing my teeth were getting yellow no matter how much I brushed. I tried whitening toothpaste. I tried teeth whiteners from the department store and that wasn't working. I was online looking for a teeth whitening method that worked for cigarette smokers. I accidently found an ad for a truly free e-cig and, liking free stuff, I ordered it. I figured it might help with the teeth whitening thing if I stopped smoking also. While waiting on my first vapemail I started researching vaping and new if I liked it I would never go back to analogs. That was a decision for my health, not just my teeth. As it turned out I LOVED it. I have been smoke-free for a month+ now and not only have I saved money, I'm feeling healthier and, low and behold, my teeth are whitening up. A win-win-win for me.
