New research led by a public health expert at the University suggests water fluoridation in England is linked to higher rates of underactive thyroid.
Professor Stephen Peckham, of the University’s Centre for Health Service Studies (CHSS), says a switch to other approaches to protecting tooth health should be considered.
In research published in the Journal of Epidemiology & Community Health , Professor Peckham and the research team identified that water fluoridation above a certain level is linked to 30% higher than expected rate of underactive thyroid (hypothyroidism) in England.
