5 famous toothpastes recalled or ditched for unsafe ingredients
Yesterday’s Innovation, Today’s Cautionary Tale
The history of consumer oral care is marked by an evolution in safety and science. While modern toothpastes adhere to strict safety guidelines, earlier decades saw manufacturers experimenting with aggressive formulas promising dazzling results. Unfortunately, some of these “innovations” contained ingredients that were later revealed to be abrasive, highly irritating, or outright toxic, leading to recalls and quiet discontinuations. These historical examples serve as a critical reminder of how far oral health science has advanced.
The core lesson from these discontinued products is simple: marketing claims must always be vetted by safety data. Relying on aggressive cleaning methods often compromised the long-term integrity of oral health.
The Era of Unsafe Formulas: Five Notable Discontinuations
1. Colgate Dental Cream with Hexachlorophene
During the 1960s and early 1970s, Colgate Dental Cream with Hexachlorophene was aggressively marketed as a germ-killing powerhouse. Hexachlorophene was a popular antiseptic used widely in medical and consumer products. However, extensive research later confirmed that hexachlorophene could be absorbed through the skin and oral tissues, resulting in neurological damage in high doses. Following reports of toxicity, the FDA imposed severe restrictions on the chemical, prompting Colgate to rapidly discontinue the formula.
2. Ultra Brite with Tuxedo Whitening Granules
The original formula for Ultra Brite—a popular, strong mint paste marketed throughout the ’70s and ’80s—gained notoriety for its highly abrasive “tuxedo whitening granules.” These micro-abrasive particles were intended to polish teeth but proved to be far too harsh for regular use. Dentists and consumers eventually noted that the granules contributed to enamel erosion and gum irritation. Due to mounting concerns over enamel wear and chemical irritants, the original abrasive formula was eventually discontinued.
3. Ipana Toothpaste with Hexylresorcinol
Ipana Toothpaste was once a household name, famous for its branding and “Bucky Beaver” mascot. However, its mid-century formulation contained hexylresorcinol, an antiseptic that was later associated with tissue irritation and toxicity concerns in oral-care applications. While small amounts were initially deemed safe, the concerns over long-term exposure led to the formula’s quiet disappearance from shelves. The Ipana brand eventually disappeared from the U.S. market altogether.
 
4. Original Pearl Drops Tooth Polish
Pearl Drops positioned itself as a glamorous, cosmetic tooth polish rather than a standard toothpaste. Its distinct shimmering quality came from finely ground pumice mixed with peroxide. While the product promised a “dazzling smile,” the early formula was judged to be far too abrasive for everyday brushing. Dentists noted that regular users experienced increasing enamel thinning and tooth sensitivity. Concerns about the pumice content ultimately forced Pearl Drops to discontinue the original formula and pivot toward gentler, less abrasive cosmetic alternatives.
5. Burma-Shave Toothpaste with Harsh Detergents
More famous for its roadside signs, Burma-Shave also produced toothpastes that heavily utilized early synthetic detergents to create a highly aggressive foaming action. These harsh detergents were later discovered to be significant irritants, causing mouth irritation, tissue dryness, and allergic reactions. As the market shifted toward safer, milder surfactants, the detergent-heavy formula was discontinued, marking the end of the brand’s foray into oral hygiene products.
These five discontinued products, despite their varying roles in consumer history, collectively serve as a powerful reminder of why modern oral care mandates strict ingredient safety. Today’s formulas are precision-engineered to deliver effective cleaning without the severe neurological or physical risks associated with yesterday’s toxic or overly harsh ingredients.
