Frequent waking from teething - help!

My LO is 7.5 months old and had been sleeping through the night since about 3 months old. I’m talking 11-12 hours of uninterrupted bliss. I was one spoiled mama!

She has not cut any teeth yet, but has been teething (excessive drool, itchy gum, etc) since 4 months old. Starting last week, she has been waking frequently due to what I’m assuming is teething pain. Nursing, bottles, cosleeping - nothing has seemed to help.

Any suggestions on how to alleviate her pain so mama, and most importantly baby, can get a good nights rest?
