What is irreversible pulpitis?

1. A condition that heals spontaneously

2. A condition where the pulp cannot heal itself

3. A type of caries without symptoms

4. An acute form of gum disease

The correct answer is: A condition where the pulp cannot heal itself

Irreversible pulpitis is characterized by the inability of the dental pulp, the innermost part of the tooth containing nerves and blood vessels, to heal itself after becoming inflamed due to infection, trauma, or decay. This condition typically arises when the pulp tissue is severely damaged, often leading to a significant amount of pain and sensitivity to temperature changes, as the inflammation puts pressure on the nerves within the pulp chamber. Patients with irreversible pulpitis usually require treatment such as root canal therapy to remove the affected pulp and prevent further complications, including tooth loss. Unlike conditions that heal spontaneously or that may resolve without intervention, irreversible pulpitis indicates a permanent state of pulp damage, making it critical for dental professionals to address promptly to alleviate pain and save the tooth.
