Eating too much sugar can cause tooth decay.

But even if you have healthy eating habits, exercise regularly and brush frequently, you can still be at risk of dental erosion.

Prolonged exposure of the teeth to an acidic environment can dissolve or eat away the enamel surface of the teeth.

This can occur when acidic drinks are sipped over a prolonged period of time, rather than consumed with a meal. When strong acid is frequently present, the mouth's natural defence system can no longer deal with the problem, and faster tooth wear occurs. Sometimes erosion results in the soft inner part of the tooth being exposed which can cause sensitivity.
