Fever with Teething ... Myth or Reality??

So, her fever's still up at night ... low grade ... but there. Today I noticed the corners of molars piercing through on both upper sides. I've heard molars are tough and take a couple months to come in and it's hard to believe she's having this fever for any other reason ... BUT, the doc says it's a myth. The American Academy of Pediatrics book I have as well as everything else I've ever read says they can get a low grade fever from teething. What gives?
