Tooth Pain Emergency: Signs You Should See a Dentist Immediately

Seek immediate care if the pain is severe or throbbing, wakes you up at night, radiates to the jaw, ear, or head, or comes with swelling or fever. These patterns point to infection, nerve damage, or advanced decay rather than ordinary sensitivity, and they rarely settle down on their own.

The most common causes are deep cavities, infected or abscessed teeth, cracked or fractured teeth, and exposed tooth nerves. Each of these irritates or inflames the nerve inside the tooth, which is why the pain can be so intense and constant. An exam and imaging identify which one is responsible.

Waiting it out is not advised. Pain that fades can mean the nerve has died rather than that the problem resolved, while the underlying infection keeps spreading. Over-the-counter pain relief may mask symptoms for a while but does nothing about the cause, so the tooth continues to deteriorate.

Not always, but persistent deep pain often signals that the nerve inside the tooth is inflamed or infected, and root canal treatment is the usual way to save the tooth in that situation. Some cases turn out to be decay that a filling can handle. Only an exam and imaging can tell the difference.
