Polar bears are one of the eight species of bears - the other seven being brown bears (grizzlies), black bears, sun bears, moon bears, spectacles bears, sloth bears, and panda bears.
This confusion might arise from the red panda, which is actually not a bear but more closely related to the raccoon - but nonetheless bears both morphological and behavioral similarities to the giant panda.
In response to the original question - I think having the bear go away would be the worst thing for an author. Insecurity is one of the side-effects of concern. The only way I know of the make the bear go away is to not care about the quality of the work.
