Irreversible pulpitis in a primary tooth is indicated by persistent, ongoing inflammation of the pulp with signs that affect surrounding tissues. Spontaneous pain means the tooth hurts without any stimulus, showing the pulp is actively inflamed and cannot recover. Lingering pain after a stimulus (for example, after a cold test) suggests the pulp’s nerves are irritated in a way that does not resolve quickly. Tenderness to percussion points to inflammation extending to the periapical tissues, and swelling reflects an acute inflammatory process that may involve soft tissues around the tooth. Taken together, these signs indicate the pulp cannot heal and an endodontic or extraction approach is needed.

Intermittent pain with cold stimulus is more typical of reversible pulpitis, where the pulp inflammation is mild and can still recover. No symptoms do not indicate irreversible pulpitis. Pain only with sweets could be dentin hypersensitivity or caries without irreversible pulpitis.
