How can i get my baby to sleep through the night?

My 8 month old is teething. Lately, her wonderful sleep patter of 10 to 6 has come to a grinding halt.She wakes up in between 1 and 2 am. I used to be able to nurse her and put her right back down. She wakes right back up these days. She cries and cries and doesn't go back to sleep until around 3. Does anyone have any suggestions?
