How long before toothache stops

A toothache may settle briefly, but pain that persists or returns usually needs dental examination because the cause can remain active.

Pain can arise from decay reaching dentin or pulp, a cracked tooth, an abscess, gum inflammation, exposed root dentin, or pressure from an erupting tooth. Pain relief does not show that the underlying problem has healed.

Protect the tooth from extreme temperatures, keep the area clean, and use a suitable labelled pain reliever if appropriate for your health history. Do not place chemicals or tablets on the tooth or delay care because the pain temporarily fades.

Seek urgent care for facial swelling, fever, pus, difficulty swallowing or breathing, severe pain, or a toothache after injury. Book an examination for pain that lasts, wakes you, or returns with chewing or temperature changes.

Ask what structure is causing the pain and whether testing or an X-ray is needed. Ask which treatment will preserve the tooth and what could happen if the pain is left untreated.
