Sensitivity

If you experience occasional discomfort or pain when brushing your teeth, or when eating or drinking cold, hot or acidic food, you probably suffer from sensitive teeth.

This isn't necessarily a sign that your teeth are weak. And, despite common perceptions, your tooth sensitivity may not be due to ageing or hereditary factors.

Beneath the protective enamel coating of teeth is a highly porous layer called dentine. Once this dentine becomes exposed, the nerve in the centre of the tooth becomes susceptible to stimuli and responds with a short sharp pain.

The usual reason for exposed dentine is receding gums, which commonly results from over-enthusiastic brushing or gum disease.
