Sensodyne Extra Fresh Rapid Relief – which launched at the “end of February” – will leave patients’ mouths “feeling clean and fresh” with its “improved taste profile”, GSK claimed.

“The product combines stannous fluoride with bio-adhesive polymer, for fast relief and long-lasting protection from tooth sensitivity,” the manufacturer added.

Sensodyne brand manager Olivia Babbington said: “Sensodyne recently became a £100 million brand in the UK. Rapid Relief is our fastest acting sensitivity toothpaste yet.”

The launch will be supported by an £8m advertising campaign over TV and online, GSK said.

One 75ml tube of Sensodyne Extra Fresh Rapid Relief retails at £5.00.
