I came from a childhood of getting a severe lack of maintenance on my teeth, so they are in rough shape, mainly my molars. And being a young adult (22) I have a not so great job with no coverage, it is hard to get in to the dentist regularly for the work I need on them. I pretty much have eliminated candy, soda, and anything ridiculous. I take care of them great now, flossing, brushing after measure, but it only keeps them from getting worse. Quitting smoking has definitely helped as well, I have noticed a huge improvement, thats for sure. If I had one thing I could change about my physical appearance it would be nice, healthy teeth!
