                            Heigh-ho, heigh-ho …. maybe off to work you shouldn’t go.
                                
                            The symptoms can be hard to spot.

                            Is this something you need to be worried about?
                                
                            Who flosses most frequently? What’s the best technique? And the big question: Are you flossing every day?
