Can scar tissue from an upper lip fernectomy really hinder teeth from straightening? I have had braces once already, but my top two teeth still have a gap, caused by a strong frenum. They are basically growing sideways, into each other. This causes a "v" shaped gap in my two front teeth--it looks like I have pepper stuck between them! An orthodontist told me that he can only correct this by putting braces on again, and after they are off proceeding with a fernectomy. He says that doing the fernectomy first will cause scar tissue, which will hinder my teeth from straightening, and that a retainer will not correct this problem, either. It sounds like it makes sense. Or is he just trying to make a few extra bucks?
