Can my crowding and overjet be corrected without extraction (29 years old)? (Photo)

I am 29 and had been contemplating getting braces for years but never trusted dentist from where I came from, now recently having moved to the US I have finally decided to do it. I need to ask whether crowding and overjet could both be corrected without extraction. My concern with extraction is that I have TMD which I have somehow managed to improve on my own hence i dont want to risk any changes to my bite. The very least I would hope for is correction of crowding without increase in overjet.
