Breastfeeding mommas, I need your help.

My daughter is 9 months old now, I've breastfed since birth. She has 4 front top teeth, 2 bottom front teeth & she's cutting all 4 of her 1 year molars now. She also has a lip & tongue tie which has always made her never be able to latch correctly. We've worked around it & she's a big, healthy 27 lb girl. She eats great but recently, along with her only getting the tip of my nipple which causes me to get raw, she's started biting. I don't mean a little chomp here & there. I mean biting down & breaking skin. Earlier, she bit down on me & was almost like she was trying to grind her teeth together on me & I tried pulling away, she bit harder. I tried to put my finger in her mouth to get her to let go & she bit even harder. It ended with me lightly flicking her cheek to get her off of me. I have 2 deep holes in either side of my right nipple that bled for about 15 minutes. It finally stopped bleeding but now it's on fire!! Where she doesn't latch completely, she can be in the middle of eating & just bite because her tongue isn't placed correctly. It's more like she's sucking like she's puffing on a cigarette, than nursing. I've tried watching for cues & it's just so random.. I've tried saying no biting or stop feeding her for a few minutes & nothing helps. She doesn't seem to be amused by it either & I try not to let out any noises so she won't try to get me to do it again by biting. She won't take a pacifier, or a bottle. & She uses me for comfort & nurses to sleep, we co sleep. I really want to breastfeed for atleast a year but I'm getting so frustrated with being bitten like this. I don't know what to do. If anyone has any helpful advice, please, I'm open to suggestion.
