Australia - dentist for 31 years

As a dentist, Lee is on the frontline when it comes to the dental health of a community. He has seen it improve markedly with the introduction of fluoride into water systems and then fall away again. "It's been a bell curve. When I first started out as a dentist dental health was pretty crook - there was no fluoride in water supplies. Then we saw the state of people's teeth improve with the introduction of flouride but the trend in recent times has been back towards dental decay, particularly in children." Lee puts this down to what people are eating and drinking, particularly the prevalence of soft drinks and bottled water. "People used to drink a lot of town water, but now they drink mainly bottled which, of course, doesn't contain fluoride.

Fluoride in bottled water is the way to go then at least this gives choice.
