A Nitrous-Oxide Pioneer Peddles His Own Dentifrice: "Dr Colton's Vegetable Dentonic".

During the latter half of the six-year long "Panic of 1873," nitrous-oxide pioneer G.Q. Colton developed, advertised, and sold his dentifrice, "Dr Colton's Vegetable Dentonic" to supplement his dental anesthetic enterprise.

The era of whiter teeth: advertising in American dentistry 1910-1950.

It has often been argued that the public image of dentists has been tainted by association with fear and pain into an image of evil 'psychodontists' and that there is an apparent lack of 'role models' in popular film, television, art and literature concerned with dentistry. This paper argues that we get a different picture when looking at different media. Advertisements introduce into a public domain, positive images of dentistry which crucially differ from the images found in other popular media. This paper traces the public image of dentistry in early 20th-century America, as seen through dentifrice advertisements, and suggests three important reasons for studying advertisements: First, advertisements provide a supplement to studies of popular images of dentistry carried out so far. Second, advertisements have played an important part in advancing oral hygiene as a public concern. And third, advertisements provide the historian of dentistry with a unique opportunity for analyzing the complex and interwoven relationship of popular and professional discourses, since ads have acted as catalysts for professional discussions and self-reflection among dentists.

Jacob Hemet. Dentist to royalty and entrepreneur extraordinaire.

One of the most prominent dentists in late-18th century London was Jacob Hemet, member of a long family of dentists. He was appointed royal dentist to Queen Charlotte, wife of George the Third, and to George's favorite daughter, Amelia, and the Prince of Wales. He advertised widely, both in this country and in several European countries, including his native France. However, what makes him noteworthy is the fact that he was the very first person to patent a dentifrice and the first to use marketing techniques similar to those used by the foremost toothpaste manufacturers of today.

Eighteenth and nineteenth century dental restoration, treatment and consequences in a British nobleman.

This paper examines unusual eighteenth and nineteenth century dental treatment and its consequences, in a nobleman excavated from beneath St. Nicholas' Church, Sevenoaks, Kent, UK in the early 1990s. This rare archaeological case exhibits erosion of dental enamel on the labial surface of all the anterior dentition. A programme of historical research suggests that this might be attributed to the application of an acid-based dental tincture or the use of an abrasive substance to whiten the teeth. Palliative treatment for the consequence of this application was prescribed by Dr Robert Blake of Dublin. Further, it bears witness to three dental restorations, two of gold and one tin. The two gold (foil) fillings are an occlusal in the upper-right second molar and a cervical on the labial surface of the upper left canine. The tin filling is an occlusal in the upper left second molar. Excavation of the carious tissue appears to have been undertaken using a spoon shaped implement.

Sozodont powder dentifrice and Mrs. Winslow's Soothing Syrup: dental nostrums.

The Great Patent Medicine Era (1865-1907) was the golden age of secret remedies--quack, non-prescription medicinal products, sold over-the-counter. Making outrageous and unsubstantiated claims, the makers of dental nostrums purported to effectively treat stained teeth, bad breath, diseased gums, toothache and teething discomfort. No proof was required to substantiate the safety and effectiveness of these concoctions. Advertisements for patent medicines were widespread, appearing in newspapers, almanacs, magazines, trade cards and multiple other media forms. Many dental patent medicines contained acids, abrasive substances, alcohol and/or narcotics, such as heroin, cocaine and morphine. Sozodont Tooth Powder, the most widely promoted and successful dentifrice of this era, claimed to "harden and invigorate the gums, purify and perfume the breath and beautify and preserve the teeth from youth to old age." Early dental researchers found that this remedy contained harsh ingredients (such as acid, sharp abrasives and astringents) which could destroy tooth substance. Mrs. Winslow's Soothing Syrup, an extremely popular dental nostrum, was intended to quiet a fretful child during the teething process. However, it contained generous levels of alcohol and morphine sulfate which could cause coma, addiction or death in an infant. Although somewhat chemically altered, these two products were eventually removed from the market in the 1930s.

The use of sodium bicarbonate in oral hygiene products and practice.

Early dentifrices contained natural ingredients, mostly in coarse particle form, and were quite abrasive. Salts, either sodium chloride, sodium bicarbonate, or a mixture of both, have also been used for tooth cleaning because of their ready availability and low cost. Because of both their relatively low intrinsic hardness and their high solubility, another advantage is low abrasivity. Their biggest disadvantage is a salty, unpalatable taste. Many modern dentifrices that contain sodium bicarbonate, either as the sole abrasive or one of several, disguise the saltiness with flavoring and sweetening agents. An almost inverse relationship exists between the percentage of baking soda in a dentifrice and its abrasivity. Sodium bicarbonate has no anticaries activity per se but is compatible with fluoride. In high concentrations, sodium bicarbonate is bactericidal against most periodontal pathogens. Most clinical studies have not found significant differences in periodontal response to baking soda as compared with other commercial dentifrices, probably because of its rapid clearance from the gingival sulcus. Sodium bicarbonate may not be the "magic bullet" for curing dental diseases, but its safety (if ingested), low abrasivity, low cost, and compatibility with fluoride make it a consummate dentifrice ingredient.

The history of oral hygiene products: how far have we come in 6000 years?

How far have we come in the past six millennia? Numerous dental epidemiological studies indicate that people are keeping their teeth longer than over before in this century. Agents and devices have evolved, by custom and by research, to enable people, with professional assistance, to maintain good oral health. Our diets, our lifestyles and our professional colleagues have "conspired" as pathogenic influences on oral health. The profession has met the challenge by developing and perfecting a myriad of devices and agents to thwart these pathogenic factors. Patient motivation and professional acceptance of preventive dentistry procedures still remain challenges. We certainly eat well, speak well, look fine and "smell fresh"--but we also have plaque, gingivitis and dental caries. The reader can determine how much progress has been made by reflecting on his or her personal oral health status!

Royal operators for the teeth: the Hemets.

The influence of the Huguenots upon the practice of dentistry in England has received so little attention that their contribution has been largely overlooked, even though the competence of one particular family, the Hemets, led to royal appointments for three successive generations. This paper seeks to begin to redress the balance by chronicling some of the activities of this family.
