The Victorians (and their neo-heirs) on both sides of the Mormon divide have long fussed about the sensuality of Mormon polygamy. There is some evidence to support both views, and I suspect most people who have read a lot on the subject feel that there was some sensuality associated with a practice whose basis was far from simply sensual. I believe, though, that I have cracked the case, discovering irrefutable evidence that there wasn’t much kissing in polygamy.
John Taylor in Nauvoo’s secular newspaper in spring 1843 reprinted an advertisement of a Mrs. Child from the New York Advertiser (if only the media were so honest in their naming conventions now) regarding methods for controlling “a bad breath” (the pseudo-scientific advertisers would call this “halitosis” now):
the careful removal of substances between the teeth, rinsing the mouth after meals, and bit of charcoal held in the mouth after, will always cure a bad breath.–Charcoal used as a dentrfrice [sic], (that is rubbed on in powder with a brush) is apt to injure the enamel; but a lump of it held in the mouth two or three times a week and slowly chewed, has a wonderful power to preserve the teeth and purify the breath. The action is purely chemical. It counteracts the acid arising from a disordered stomach, or food decaying about the gums, and it is this acid which destroys the teeth [describing a man with rotting teeth and an obvious initial charcoal deficiency who saw the light] nature set vigorously to work to restore the breath, and the crumbled portion grew again, till the whole tooth was sound as before. Every whole tooth was sound as before. Every one knows that charcoal is an antiputrescent. It thus tends to preserve the teeth and sweeten the breath.
QED, as the pocket-protected might say, Quod Erat Demonstrandum
 Can’t believe you all didn’t object when I forgot the footnote. Here it is: “A Sovereign Remedy for an Offensive Breath,” The Wasp 1:50 (12 April 1843): 3.
