I have some serious dental problems due to physical abuse but lack insurance. Does anyone have helpful ideas?

My two front teeth are gone, I have many rotten teeth throughout my mouth. Because of this, I rarely smile. I believe it would really help my self-image if I was able to get this issue fixed, but not having dental insurance (and it's even harder getting individual insurance) is holding me back. Someone please give me some helpful hints or ideas!
