Colgate: Indianis Dentris
Colgate and Brand David Communications needed to address the widespread, unhygienic habit of Indian consumers using toothbrushes long past their recommended three-month lifespan. The client sought a disruptive, behavior-change campaign that would move beyond standard clinical messaging to make the necessity of regular replacement impossible to ignore. The goal was to drive higher purchase frequency by highlighting the hidden health risks of neglected oral care tools.
Creative Idea
The campaign framed worn-out toothbrushes as a dangerous, newly discovered botanical species.
Colgate used a botanical hoax to reframe worn-out toothbrushes as a new, harmful species called Indianis Dentris. By treating neglected oral hygiene as a scientific discovery, the campaign forced consumers to confront the reality of their unhygienic habits.
The Botanical Hoax That Fooled India
Crafting the Scientific Illusion
To make the hoax believable, the team at Hungry Films collaborated with botanists and prop designers to create hyper-realistic, mutated toothbrush specimens. These were housed in glass terrariums at the Mumbai exhibition, complete with fake scientific plaques, Latin nomenclature, and detailed growth charts. The production team utilized macro-photography and time-lapse lighting techniques to mimic the aesthetic of a high-end natural history museum, ensuring the "discovery" felt authentic enough to trigger genuine alarm among visitors.
Turning Disgust Into Data
The campaign achieved significant behavioral shifts by gamifying the replacement process. Through a dedicated microsite, users could upload photos of their old brushes to receive a "Species Analysis" - a tongue-in-cheek report detailing the bacteria levels present. This digital component drove 1.2 million unique visitors in the first month. Internal data from Colgate-Palmolive India reported a 14% increase in toothbrush sales across urban centers during the campaign period, directly correlating with the spike in social media engagement surrounding the #IndianisDentris hashtag.
A Collaborative Creative Engine
The project was a massive undertaking for the WPP@CP team, requiring seamless coordination between Brand David Communications and The Refinery. While Brand David handled the overarching strategy and narrative arc, The Refinery acted as the "visual engineering" arm, responsible for the physical installation and the intricate design of the botanical specimens. This partnership allowed the agency to pivot from traditional advertising into the realm of experiential art, effectively turning a mundane household object into a viral, cautionary tale that dominated local news cycles throughout March 2025.
