My 11 month old used to sleep through the night, now she wakes up 2-4 times crying.?

She used to sleep sound through out the night, now she wakes up AT LEAST 2 times a night crying. sometimes she chugs a bottle like she is starving and other times she just takes a binky. Last night she was up about 5 times just crying. She is cutting her top two teeth but could that be the reasoning for the disrupted sleep for this amount of time? She is already on pepcid for reflux and it helps her so i know its not that. I dont know what else to try. Any suggestions?
