Toothache can feel more intense at night because there are fewer distractions and lying down may increase pressure around an inflamed tooth. Pain is a symptom rather than a diagnosis, so even if it settles temporarily, the underlying cause may still need treatment.
Quick answer: Dental symptoms cannot be diagnosed reliably online. If pain, swelling or damage is significant, call a dentist for individual advice.
Common causes of night-time toothache
Possible causes include tooth decay, a cracked tooth, an inflamed or infected dental nerve, gum infection, food trapped between teeth, a loose filling or teeth grinding. Pain that is triggered by hot, cold or biting gives the dentist useful clues, but an examination and sometimes an X-ray are needed to confirm the cause.
What you can do tonight
Use pain relief only if it is suitable for you and follow the packet instructions; a pharmacist can advise. Eat soft foods, avoid very hot, cold or sugary items, and try not to chew on the painful side. Gently clean the area. Children under 16 should not take aspirin, and aspirin should never be placed directly against a tooth or gum.
When to contact a dentist
Arrange an assessment if pain lasts more than two days, keeps returning, wakes you repeatedly, is not controlled by appropriate pain relief, or comes with pain on biting, a bad taste, fever or swelling. Earlier assessment usually gives more treatment choices.
Emergency warning signs
Go to A&E or call 999 if swelling around the mouth or neck affects breathing, swallowing or speaking, or if swelling extends towards the eye. If you need urgent dental help outside normal hours and cannot contact a dentist, use NHS 111.
Frequently asked questions
Will antibiotics cure toothache?
Not usually. Many toothaches need dental treatment to remove decay, repair a crack, treat the nerve or address gum disease. Antibiotics are used only for particular infections.
Can toothache disappear on its own?
Symptoms can fade when a dental nerve changes or pressure reduces, but the cause may remain. A dentist should assess persistent or recurring pain.
