Teething pain relief...HELP!

Alicia
I believe my 5 month old little girl is teething. She is extremely cranky and needy. Occasional cough and sneeze(not sure if these are signs). I bought oragel but am afraid to use it because it's not recommended in babies under 2yrs...? Had anyone used it? What is everyone using to relieve pain? I do have teething rings for her as well.
