Sensitive Teeth

Tooth Sensitivity

Tooth sensitivity occurs commonly in the many people due to a variety of causes.

There are two main reasons for tooth sensitivity:

Dentinal sensitivity occurs when there is exposure of the inner layer of  a tooth (dentin or root surface). These surfaces are normally covered by the protective enamel layer or gum tissue (in the case of root sensitivity). When the dentin is exposed, cold or hot temperature or pressure can affect nerve branches that are sitting in tiny openings (tubules) inside the dentin, causing sensitivity.

Pulpal sensitivity is a reaction of the tooth's nerve. These nerves and blood vessels, referred to as "the Pulp" occupy the center of each tooth.  Inflammation of this tissue can result from many causes, including decay or infection, a deep filling, excessive pressure from clenching or grinding, or a cracked or broken tooth.

What are some common causes of tooth sensitivity?

There are many things that could trigger discomfort or pain for those with sensitive teeth. Common causes include cold foods and drinks, hot foods and drinks, sweet foods, cold air, improper tooth brushing and even poorly applied whitening techniques.
