If the baby was refusing one breast after a teething episode (I think that was what the mom thought), and that breast got neglected a bit, couldn't it be involuting and salty tasting? To remedy this, mother could express more to increase supply (relactate on that side I guess) and see if that improves the taste. However, I do agree that an examination should be suggested as well.
