SA toothpaste war: Sensodyne loses another fight over dentist claim

Sensodyne, owned by Haleon, lost an appeal to advertise its toothpaste as the 'No.1 dentist-recommended' brand without specifying it's for sensitive teeth. The Advertising Regulatory Board (ARB) ruled the claim misleading, requiring equal prominence for the sensitivity disclaimer. Haleon argued the ARB lacked jurisdiction, but the committee upheld the ruling, citing a Supreme Court precedent.
