Okay, my kids are older (12 and 14) now, so I'm out of touch, but here goes: Neither of them took bottles to bed, cuz I just held them, bounced a little and sang to them before putting them in their cribs, so we never had this problem. But when the older was was 2, the next one came. I was not ABOUT to wean her from a bottle while her younger sister got one. It seemed mean. She drank from a real cup at meal times, but she loved apple juice and drank it from a bottle which she carried around in her teeth half the day. My mother ALWAYS complained, and told me I was doing bad things for my child. For the record, yes she had braces, because she had more teeth than she had mouth -- and that had nothing to do with the bottle. She has never had a cavity in her life -- even after the braces came off ! I would be more concerned about a thumb in the mouth as your child ages, than I would be about a bottle. Our neighbor's child was still sucking her thumb at 10, and her front teeth protruded enough that she couldn't enunciate. The bottle can be taken away, the thumb can't. :-)
bottom line: you have to do what is right for you and your family, your child included. If you have the time and energy to hold her with a stuffed animal and rock her to sleep, then it might be easier to give up the bottle. Otherwise, is the bottle really going to warp her for life ? I doubt it. It may not be the best thing in the world, but, if she is loved and nurtured and allowed to grow at her own pace, and she feels safe within her boundaries, and is safe even when she pushes past them and is disciplined, she'll grow up well, and you'll be amazed and honored to be her mom when she's grown.
If YOU want to break the bottle habit, maybe an easy way to start is to have the bottle while reading a book, and have some hugging, quiet time BEFORE bed. Then when you tuck her in, the bottle is already empty and gone. Later, you can keep the story, and the hugs, so there's a bedtime ritual, but no bottle. ??
