Tooth sensitivity commonly occurs when the protective layers of teeth are worn away, revealing a bony tissue called dentin. This tissue contains microscopic hollow tubes that, when exposed, allow hot and cold liquids and food to contact the underlying nerve endings in the teeth, causing pain.

The most common factor related to sensitive teeth is gum recession. When the gum begins to recede, the tooths root becomes exposed, resulting in sensitivity. Other causes of sensitive teeth are toothbrush abrasion, periodontal therapy - treatment for periodontal disease, tooth decay or faulty restorations, excessive grinding or excessive bleaching.
