Matt Hopcraft is a dental public health expert and CEO of the Australian Dental Association's Victorian branch and he says fruit juice can be problematic for oral health for a couple of reasons. Fruit juices, especially citrus juices such as orange juice, are highly acidic and drinking them too often can lead to dental erosion. "Over time, the acid can completely erode through the enamel and expose the underlying dentine, causing extreme sensitivity," Dr Hopcraft says. The sugars in fruit juices also feed the bacteria in our mouth and on our teeth. "The bacteria in plaque convert these sugars into acid that attack the tooth enamel and can eventually lead to a cavity," Dr Hopcraft says.
