What was advertised in a colonial American newspaper 250 years ago today?

“Each pot is sealed with his coat of arms, as in the margin of the directions, to prevent fraud.”

For quite some time John Baker, “SURGEON DENTIST,” had advertised his services to the better sorts and others and other residents of Boston in the newspapers published there, but in the spring of 1768 he migrated to New York and informed “the gentry” that “he will wait on receiving their commands.” He announced that he “cures the scurvy in the gums” and “makes artificial teeth,” just a few of the many aspects of dental hygiene and health he addressed in the lengthy notice he inserted in the New-York Journal.

In addition to those various services, the itinerant surgeon dentist also hawked a product that readers could purchase with or without undergoing any of the procedures he performed. A manicule drew attention to Baker’s “Dentrific … for preserving the teeth and gums.” Here Baker used an alternate spelling for “dentifrice,” a precursor to toothpaste described by the Oxford English Dictionary as “a powder or other preparation for rubbing or cleansing the teeth.” Baker provided “proper directions,” presumably a printed sheet or pamphlet, with each purchase.

He also realized the potential for counterfeits to circulate in a marketplace with little regulation of medicines. To that end, the inserted a nota bene to announce that “Each pot is sealed with his coat of arms, as in the margin of the directions, to prevent fraud.” Whether Baker actually anticipated spurious dentifrices attributed to him, this proclamation enhanced his marketing efforts. It implied that his dentifrice was so effective that others would indeed attempt to peddle substitutes that they passed off as authentic. It also allowed him to assert that he possessed his own coat of arms, which now doubled as a trademark to readily identify his product. Earlier in the advertisement he declared that he had provided his services “to the principal nobility, gentry, and others of Great-Britain, France, Ireland, and other principal Places in Europe.” Invoking his own coat of arms accentuated that claim, suggesting that his treatments were so effective that clients of means and influence had obtained his services and been satisfied with the results. As a newcomer to New York, Baker could not rely on a reputation built over time through extended interactions with local residents as a means of attracting new patients. Instead, he used his dentifrice, his coat of arms, and his own reports concerning his previous clients to achieve recognition and encourage prospective patients to engage his services in a new city.
