Do I need to call the dr

So my LO is 7 months old and fro the past couple of days she has been grabbing at her right hear all day basically and when we touch it she cries and she cries when I put bows on her that cover her hand in these days... I know she just cut a second tooth and she hasn’t have a fever. Do I need to call her dr about possible ear infection? Or could it jut be teething? This is my first baby and I have no clue
