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. Those patterns point to infection, nerve damage, or advanced decay rather than passing sensitivity. Pain of that kind does not improve on its own.

The usual causes are deep cavities, an infected or abscessed tooth, a cracked or fractured tooth, and exposed tooth nerves. Each involves irritation or infection reaching the pulp, the sensitive tissue inside the tooth. Because the pulp sits inside a rigid chamber, the pressure of inflammation produces pain that is often intense.

Pain sometimes fades, but that is not proof the problem resolved. When an infected nerve dies, the pain can stop while the infection continues spreading into the bone below. Treating a disappearing toothache as a cure is one of the more common reasons a savable tooth eventually ends up needing extraction.

Not always, but deep cavities and infected nerves often do require root canal treatment to save the tooth. The dentist examines the tooth, tests the nerve, and takes an X-ray before deciding. Some cases need only a filling or gum treatment. Emergency care relieves the pain first, then plans the definitive repair.
