Sensitive Teeth

Tooth is made up of an outer layer called enamel and an inner layer called dentine. The hard outer enamel protects the dentine which is softer and more sensitive to external stimuli such as hot and cold, and is more prone to wear. Sensitive teeth can be caused by:

• Worn tooth enamel from using a hard toothbrush and using a hard grip while brushing aggressively.
• Tooth erosion due to highly acidic foods and beverages.
• Tooth decay, worn leaky fillings and broken teeth that expose the dentin of your tooth.
• Gum recession that leaves your root surface exposed.
• Grinding your teeth at night.
• Post dental treatment sensitivity – common, but temporary, especially with procedures such as crowns, fillings and tooth bleaching.

The cause of sensitive teeth needs to be determined first. Treatment could be as simple as using a desensitising toothpaste (such as Sensodyne), or it may involve protection of an exposed dentine or nerve ending using fillings or crowns. However, if your discomfort comes from gum loss exposing root surfaces, we may suggest a gum graft to protect the root surface and support of your tooth.
