In reversible 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. In irreversible pulpitis, pain occurs spontaneously or lingers minutes after the stimulus (usually heat, less frequently cold) is removed.

How do I know if I have irreversible pulpitis?

If your pain occurs with temperature extremes but goes away quickly, you may have a reversible condition. But if the pain is intense, lingers after temperature changes, occurs spontaneously, or is referred to other teeth, making it hard to determine the exact location, you may have irreversible pulpitis.

How do you get irreversible pulpitis?

Irreversible pulpitis occurs when the inflammation of the pulp of a tooth causes pain that lasts, lingers, or does not go away even if the irritant is removed from the tooth. This is a sign that the pulp of your tooth is damaged beyond repair. This can happen with dental trauma or injury to a tooth.
