Tooth Pain Emergency: Signs You Should See a Dentist Immediately

Tooth pain is an emergency when it is severe, keeps you awake, throbs constantly, or comes with swelling, fever, or a bad taste in the mouth. Pain triggered by pressure or heat that lingers for minutes afterward also points to nerve involvement. These signs suggest infection or damage that will not settle without treatment.

The most common causes are deep decay reaching the nerve, an infected or dying pulp, a dental abscess, a cracked tooth, and advanced gum disease. Trauma, a lost filling, or an erupting wisdom tooth can also produce intense pain. Because the causes need different treatments, a dentist has to identify the source first.

No. Over the counter pain relief can make an infected tooth bearable for a short time, but it does nothing about the bacteria causing the problem. Antibiotics may reduce swelling, yet the infection usually returns unless the source is treated, typically with root canal therapy or extraction along with drainage where that is needed.

Sudden relief is not always good news. When the nerve inside a badly infected tooth dies, the pain can disappear even though the bacteria remain and continue spreading into the bone around the root. Many people who ignore this quiet phase return later with swelling. A dentist should still examine a tooth that stopped aching.
