fever - teething?

Hey moms! My LO has 3 teeth all coming in at the same time. She's been running a fever since Saturday & is cranky, wants to be held a lot. No trouble sleeping at night or eating/drinking. I called the advice nurse & she said no need to bring her in but this is Day 3 with a 101.5 fever. Should I take her in? What can they do if it's teething?
