While it is common knowledge that highly acidic foodstuffs can have a detrimental impact on tooth enamel, scientists have now discovered that alkaline-rich items could also cause erosion.

Research carried out at the University of Gothenburg has revealed that alkaline substances can damage the organic parts of a teeth, leading to a weakening of the enamel and a greater chance of decay, a situation which could result in a trip to see the emergency dentist.

Fabian Taube, a researcher who took part in the study, said: "While occupational oral damage from alkaline is less common than damage caused by acidic substances, it can be a problem."

A study carried out by scientists at Johannes Gutenberg University in Germany recently showed that white wine could be more damaging to teeth then red.

It revealed that while red wine can stain teeth, white could wear away tooth enamel, leading to a greater likelihood of white wine drinkers developing sensitive teeth.
