I remember as a kid getting called and waiting in dread for the loudspeaker to come over to say, "Chris Luxon, can you please go to the dental nurse." in what we knew as the murder house. Away they'd go on your teeth and there would be multiple fillings in each tooth, and I don't know whether they got pleasure from it, but I certainly know that I didn't. But, actually, sadly, it hasn't improved much over that time.
