Pulpitis
Symptoms and Signs of Pulpitis
Inreversible pulpitis,pain occurs when a stimulus (usually cold or sweet) is applied to the tooth. When the stimulus is removed, the pain ceases within 1 to 2 seconds. Inirreversible pulpitis,pain occurs spontaneously or lingers minutes after the stimulus (usually heat, less frequently cold) is removed. A patient may have difficulty locating the tooth from which the pain originates, even confusing the maxillary and mandibular arches (but not the left and right sides of the mouth). The pain may then cease for several days because of pulpal necrosis. When pulpal necrosis is complete, the pulp no longer responds to hot or cold but often responds to percussion. As infection develops and extends through the apical foramen, the tooth becomes exquisitely sensitive to pressure and percussion. A periapical (dentoalveolar) abscess elevates the tooth from its socket, and the tooth feels “high” when the patient bites down.
