Irreversible pulpitis is characterized by inflammation of the dental pulp that is no longer capable of healing. The primary symptom associated with this condition is constant sharp pain, which often occurs spontaneously and can be severe. This intense pain often persists regardless of external stimuli, such as hot or cold.

In irreversible pulpitis, the pain is typically categorized as throbbing or sharp, and may lead to significant discomfort that disrupts daily activities or sleep. This clear symptom differentiates irreversible pulpitis from other dental issues where pain may be intermittent or less severe, such as in cases of reversible pulpitis or minor tooth sensitivity.

The other options reflect symptoms that either suggest a less severe dental issue or indicate insufficient discomfort that typically would not be associated with irreversible pulpitis. Consequently, the presence of constant sharp pain is a defining characteristic of this condition.
