It has been close to 2 years since I started my invisalign treatment. While I'm still a few months away to the end of my treatment, I'm already happy to see how my teeth have straightened so far. My teeth used to be so crooked, with my upper front teeth pointing almost 45 degree outwards. There were also big gaps at my lower teeth. Beside straightening my teeth, the treatment also helped me to keep up my oral hygiene and solve my long term germ bleeding issue. The entire experience has been amazing and it's one of my best decision made!
