M.S.
Can't help with the pacifier as mine didn't use them but I think 1 might be pretty young to take it away. I usually hear people doing this around 2ish.
As for brushing the teeth. The earlier you start the easier it will be in the long run. Start with just wiping the gums when they have no teeth then after they have teeth move on to a toothbrush and try to brush morning and night. At the least, brush before bed but try to get in the habit of twice a day. You'll want to be the one doing the brushing until your daughter can brush all her teeth on her own for about 2 minutes. This is usually around age 5-7. With both of mine, ages 2 and 5, I brush their teeth and get all the sugar bugs and then I let them have a turn. Also, make sure you buy her the right size toothbrush - too big and it may hurt and non-fluoride toothpaste. With mine when they were younger, we would sing the ABC's twice while brushing.
Good luck!
