Eh don't worry about it too much...my little cousin is going on 4 and she's still drinking from a bottle, but she cries and cries if she can't get milk in a bottle; for some odd reason she can drink water and juice from a cup through a straw but she only takes milk in a bottle. I don't know why...kinda funny though.
Another fun story is when my aunt (who is ironically enough my little cousin's mom) decided it was time for me to quit drinking from a bottle and she took it and simply threw it in the garbage with me watching. But I didn't cry or flicnh; I simply looked her right in the eye and told her "It's okay. Grandma will get me a new one" and she did too
Hahahaha.
But I wouldn't be concerned with weining (spelling??) until the little whipper-snapper is 2. I may have drank from a bottle for many years but I have no speech problems or dental problems; I never needed braces. Just my own opinion here but I wish thee the best of luck with this no matter how you choose to handle it. ^.^

, I think around 1year old is a good time to have bubs off the bottle. 
Start earlier by replacing a bottle feed with a sipping cup. The hardest to stop will be the bottles they have at sleep time. 
But with persistance they will sleep with out it. If you leave it too long it becomes a habit just like any other and very hard to break.
