What are the symptoms of tooth nerve pain?

Pulpitis-induced tooth nerve pain mainly presents in the following ways: 1. Spontaneous and paroxysmal pain: The affected tooth suddenly experiences severe pain without any external stimulation. The pain is sharp and paroxysmal, meaning it occurs intermittently—sometimes painful, sometimes relieved—but the onset time is unpredictable. 2. Nighttime pain: Pain often intensifies at night and is more severe compared to daytime, frequently causing insomnia or even waking patients from sleep. 3. Temperature-induced pain: Pain symptoms are triggered or worsened by consuming hot or cold foods. In later stages of pulpitis, a phenomenon known as "heat pain with cold relief" may occur, whereby holding cold water in the mouth or inhaling cold air temporarily alleviates the pain. 4. Difficulty in localizing the pain: Patients often cannot accurately identify the affected tooth. The pain is usually radiating or referred, extending to one side of the head or face, making it difficult to determine the exact location of the discomfort. It is recommended to seek timely medical attention and receive professional treatment.
