I always thought I would get my bottom teeth fixed "eventually" but never got around to it. My teeth are very tight and shreds dental floss, even the shred-proof kind. It was an annoyance, but not a big deal because most people don't look at your bottom teeth.
However, I was starting to have some other problems, and found out that by straightening my teeth I could clean them more easily and prevent further problems down the road. I work long hours and have a very busy schedule, so the thought of braces just sounded too inconvenient, not to mention painful. Starting invisalign has allowed me to take care of my health while not interfering with my other responsibilities.
