Like someone else said, it's easy to fall into the trap of thinking your child is advanced because he or she met a few milestones ahead of schedule. However, teething and weaning from formula/breastmilk/bottles are in no way connected to the child's developmental ability.
Also as someone else said, early walkers are often later talkers because they've been focusing on gross motor skills rather than language skills. Kids tend to really focus on just one skill at a time, and when that happens, you may notice a stall in other areas. That's perfectly normal and is no predictor of future development (except in the case of significant delays).
My oldest was actually a "late" roller, crawler, walker, and talker. She never really rolled. She didn't crawl until almost 10 months, didn't walk until 13 months, and didn't say more than a couple words until about 14 months. She was an early sitter (4 months), and I think she spent those early months working on fine motor skills and language comprehension. She understood most of what we were saying, but didn't say any of it herself. And when she did start to talk, her speech pattern was halting, and her pronunciation was not good at all. However, by age 3, she spoke very clearly -- even saying the difficult "R" sound. She's now 6 years old, in the 1st grade, and is advanced for her age/grade -- she reads at a 3-4th grade reading level, has a bigger vocabulary and clearer speech than many of her peers, etc. I'm not trying to brag -- I'm just trying to show that even though they may start out with what seems like a "delay," it's not necessarily an indication of future ability.
And FWIW, my younger two both walked and talked earlier than my oldest, but my 5-year-old still struggles with some speech (at a perfectly normal level for her age). My 2-year-old's speech is improving rapidly, so he may be speaking as clearly as my oldest by age 3, but he's also doing just fine for his age.
Take a deep breath, and definitely consult with your doctor if you're concerned, but there is a wide range of developmental ability at these early ages, and I imagine your daughter will be talking before you know it.
