Sir Peter Gluckman served as the chief science advisor to three Prime Ministers, from 2009 to 2018. He is the managing trustee of thinktank Koi Tū the Centre for Informed Futures, which has just been made an independent charitable trust.
He joins Emile Donovan to review the evidence around fluoridation.
