Tooth pain at 2am — what to do tonight

By the Berala Dental clinical team. Educational information only — this article is general information and is not a substitute for personalised dental advice. Please book a consultation to discuss your individual needs.

If you're woken by severe toothache, you can usually ease it overnight with simple measures — then get it assessed as soon as possible, because pain that wakes you often signals a problem that won't fix itself. Rinse with warm salty water, take over-the-counter pain relief as directed on the packet, keep your head slightly elevated, and avoid very hot, cold or sugary foods. Here's what's going on and what to do.

If the pain has woken you, we can look at the tooth as soon as we open.

How to ease toothache overnight

• Rinse with warm salt water — a gentle swish can help soothe the area.
• Take over-the-counter pain relief as directed on the packaging, provided it's safe for you. If you're unsure, ask a pharmacist.
• Keep your head raised with an extra pillow — lying flat can make throbbing worse.
• Use a cold compress on the outside of the cheek for swelling.
• Avoid triggers — very hot, cold, sweet or hard foods on that side.
• Floss gently in case food is trapped between teeth.

These steps manage the pain; they don't treat the cause, so still book to be seen.

Why does toothache feel worse at night?

There are a few reasons night-time toothache can feel more intense: lying down increases blood flow to the head, there are fewer distractions than during the day, and you may not have eaten or taken anything recently. It's not your imagination — but it does usually settle with the measures above.

What might be causing it

• Tooth decay reaching the sensitive inner part of the tooth
• A dental abscess or infection
• A cracked or broken tooth
• A lost or loose filling
• Gum problems or something stuck between teeth
• Grinding or clenching

Some of these are urgent, which is why persistent or severe pain should always be checked.

When is toothache a dental emergency?

Call us promptly — or seek urgent medical care — if you have:

• Facial swelling, or swelling spreading towards the eye or neck
• Difficulty breathing or swallowing (seek emergency medical help immediately)
• A high fever alongside the toothache
• Severe, unrelenting pain that isn't controlled by over-the-counter relief
• Bleeding that won't stop

Swelling and fever can indicate a spreading infection that needs prompt treatment. See our emergency page.

How we can help

We offer same-day emergency appointments Monday to Saturday. As soon as we're open, call and tell us you're in pain so we can prioritise you, find the cause, and get you comfortable.

Frequently asked questions

What's the fastest way to stop toothache at night?

A warm salt-water rinse, over-the-counter pain relief taken as directed, a cold compress on the cheek, and keeping your head elevated usually help most. These ease symptoms until you can be seen.

Should I put painkillers directly on the tooth or gum?

No — don't place tablets like aspirin against the gum, as this can burn the tissue. Take pain relief as directed on the packet instead.

Can a toothache go away on its own?

Pain can ease temporarily, but if it's caused by decay, a crack or infection, the underlying problem usually remains and can worsen. It's best to get it checked even if the pain settles.

When should I go to a hospital instead of a dentist?

Seek emergency medical care immediately if you have difficulty breathing or swallowing, or rapidly spreading facial swelling. These can be signs of a serious infection.
