How parodontax became the world's fastest selling toothpaste

The challenge for GSK’s small gum care brand, parodontax, (Corsodyl in the UK) was to convince consumers to switch from regular toothpastes to its products that also treated gum disease.

The company worked with its agencies Grey, Edelman, Geometry and PHD to tackle its communications problem. 

Strategy developed the metaphor of a journey towards socially embarrassing disease symptoms, like bad breath and bleeding gums, unless people treated the condition early.

A single creative idea was deployed internationally to maximise media spend and increase share of voice. TV ads brought impact, with other channels used to cut through with consumers in mornings or whilst travelling.

Ads outperformed on awareness and likelihood to persuade disease non-treaters to buy the brand. Incremental sales of almost £50m were generated and parodontax became the world’s fastest-growing multi-market toothpaste brand.

Clare Brosnan, Global Marketing Director, GSK, said: "As a small brand facing a huge challenge, we made a commercial decision to trade-off cultural effectiveness for global creative efficiency, in doing so freeing up extra investment for media.

"But over the course of the campaign we’ve learnt we can have both; by unlocking a universal behavioural insight that transcends culture, we’ve created an approach that is both highly efficient and very effective.

"Our results have added to company learning about multi-market brand building and helped inform the way GSK consumer healthcare approach marketing globally.

"We genuinely believe it’s a model that can be applied beyond the category, providing smaller multi-market brands the ability to challenge the status quo."
