First of all, my dentition wasn't too crooked, so I only had one tooth extracted for about 1 year and 6 months. After I did it, I felt more confident when I smiled. But the downside was that my upper lip became really small and thin. And as I lost weight around my mouth, my nasolabial folds got worse + the side of my nose. It also turned off... The black triangle was a bit annoying at first, but now it's barely noticeable.
