My teeth were so overlapping that I was very skeptical at first, I taught I was wasting my money, but it did a fantastic job. I'm 47 years old and it's one of the best decision I've made!
Of course it took 20 months instead of 12 like expected at first but time goes by so fast, and now I'm smiling with straight perfect teeth.
Throughout the process I've never experience pain that bothered me, the attachments were visible but much better than metal braces
Wish I had taken pictures of before and after.
