Extract Teeth or Rub off Teeth with Invisalign? (photo)

I am 34 years old, and my teeth is crowded and i want to fix them. i got two options from dentist till now: Option 1: extract 4 teeth( 2 from up, and 2 from down site. It does not include the wisdom teeth) Option 2: Extract two wisdom teeth. and extract one canine teeth from the bottom(the one which is not in the line), then rub off the teeth, and use the invisalign. I am concerned about getting teeth extracted. And also wonder whether rub off will ruin the teeth.Please help to advise!
