S will be 4 months Monday

Anywho she is inconsolable today and is typically a very chill baby. We've tried everything and finally got her down for a nap then she was cranky as soon as she got back up. She won't suck on paci but if we hold it there she'll gnaw on it.
So for those of you who have had teething babies, how long does the insanity last per tooth? What are your tips and tricks? She doesn't take medicine well (spits it right back out). Lots of teethers are too big for her mouth.
Thanks and I hope you all have a wonderful weekend!!
