I paid more for these than I would have if I would have opted for traditional braces. However, there are no regrets. My teeth were fine as a kid, but as an adult, things shifted and I started getting headaches from the way I bit down. I was just so grateful that the only thing I needed was straightening my bite. It is amazing how things change as you age. I love how my teeth look after using Invisalign . I could not have asked for a better option.
