My teeth were straight but they were "slightly angled". We tried fixing this by wearing retainer. Although, had some alignment issues since I don't have enough space in my mouth to fix the angulation of my teeth, and therefore would have to get 4 teeth removed. I'm going off to university in the fall, &some orthos tell me that the angulation& the alignment of my teeth can be fixed with invisalign will others say it can't. Also, my bite was corrected and now my dentist says I should get it fixed.
