My 3 month old is teething currently (I know, it's very early) and she's feeling a lot of discomfort. I'm trying teething gel currently but the effect seems to last very short, and I'm not sure if there are cases of overdose since it's a medication. As she is still very young to hold anything in her hands, teething toys are not useful. She is currently sucking her hand most of the time and she spit out her pacifier when she doesn't want it.

Are there any other solutions to it?
