What causes Sensitive Teeth?

Sensitive teeth is better understood with the anatomy of the tooth. The anatomy is divided into two portions – root and crown.

The crown portion has enamel on the top that protects the tooth from being sensitive. Because of mechanical pressure from brushing or gastric acid reflux, the tooth enamel wears out, and the second layer is exposed. This exposure of the Dentin (second layer) causes the tooth to become sensitive to cold, heat, or wind.

Cementum is the first layer on the root surface, which helps to anchor the tooth with the bone. The cementum is a skinny layer and usually wears out. With no cementum, the Dentin is exposed again. Hence, the tooth becomes sensitive due to many conditions.

A sensitive tooth is a symptom and not a condition. A tooth can be sensitive as a result of many tooth condition. Mild sensitiveness can be due mild conditions like periodontal disease or mechanical brushing. Whereas severe sensitiveness is a result of severe conditions like dental decay or tooth abscess.
