Description
People with sensitive teeth feel discomfort when the teeth are touched or when they drink or eat certain things. Dentinal sensitivity occurs when the outer protective layer of a tooth wears away. Causes include hard brushing, poor oral hygiene, untreated cavities and exposed tooth roots. Pulpal sensitivity affects the center layer of the tooth. Causes include decay or infection, a recent filling, clenching or grinding of teeth, or a cracked or broken tooth. Gums tend to recede as people get older. This may expose sensitive root surfaces.

Sensitivity to temperature or pressure. Sensitivity to cold food and drink is more common. Sensitivity to heat can be a more serious symptom.

Treatment
Dentinal sensitivity can be treated with a fluoride varnish to protect teeth. The dentist may use a laser or other treatment to reduce sensitivity. Pulpal sensitivity will be treated with a root canal if the tooth's nerve is dead or dying. The outlook for symptom relief depends on the cause of the sensitivity.
