6mm Gap in Front Teeth - Warsaw, PL

My upper teeth were moving towards left and my 6 MM gap was growing and moving from the center towards the left side of the jaw. Due to this my teeth were not grinding correctly when chewing and my face looked very asymmetrical when smiling. I therefore decided on the invisalign, which is fairly cheap in Poland. Ive so far had the invisalign for 6 weeks and im already noticing a difference. My left mid tooth has already been pushed back a little and i can feel how the teeth are getting aligned. The current plan is lower jaw 6 months and upper jaw 12 months and this wil lead to a 2mm gap in my front teeth. Which i have decided to keep.
