Sleep propped up on an extra pillow, take an over-the-counter painkiller as directed on the packet, rinse with warm salt water, and hold a cold compress against your cheek. Those 4 things get most people through to morning.
Night-time toothache is common and almost always means something needs treating rather than something that will pass. Home measures buy you hours, not a cure, so book with a Barrie dental clinic as soon as the phones open.
Why does it get worse after dark? Two reasons, and neither is bad luck.
Lying flat sends more blood to your head, which raises pressure inside an already inflamed tooth. And with no distractions, your brain has nothing else to attend to. If pain is keeping you up repeatedly, an examination is the step that actually ends it.
What to do tonight
- Raise your head. Two pillows, or sleep in a recliner. This single change helps more than people expect because it reduces blood pressure at the tooth.
- Take pain relief as directed on the package. Follow the dosing instructions and check with a pharmacist if you take other medication.
- Rinse with warm salt water. Half a teaspoon in a glass, swished gently for 30 seconds.
- Cold compress on the outside of the cheek, 15 minutes on and 15 off. Cold reduces swelling and dulls the nerve.
- Clean around the tooth gently. Trapped food between teeth causes a surprising amount of night pain, and flossing it out sometimes resolves things entirely.
- Avoid very hot, very cold and sweet things before bed.
- Clove oil on a cotton bud, applied to the tooth rather than the gum. It’s a mild temporary numbing agent.
Keep the salt water rinse gentle. Vigorous swishing on a tooth that’s recently been treated or extracted can dislodge a clot and make things considerably worse.
What not to do
Don’t put aspirin against the gum. It causes a chemical burn and does nothing for the tooth. Aspirin works through the bloodstream, so swallow it instead if it’s appropriate for you.
Don’t apply heat. Heat increases blood flow and swelling. If there’s infection, warmth can help it spread.
Don’t drink alcohol to numb it. It interacts badly with painkillers and dehydrates you.
Don’t take leftover antibiotics. They won’t touch pain from a dying nerve, and partial courses contribute to resistance.
Don’t ignore it once the pain fades. A toothache that stops suddenly often means the nerve has died, and infection is still developing underneath.
What the pain is telling you
| Type of pain | Likely cause | Treatment usually needed |
|---|---|---|
| Sharp with cold, stops quickly | Sensitivity or a small cavity | Filling or desensitising |
| Lingering ache after hot or cold | Nerve inflammation | Root canal treatment |
| Throbbing, worse lying down | Infected pulp | Root canal or extraction |
| Sharp pain on biting | Cracked tooth or high filling | Crown or adjustment |
| Dull ache with pressure | Sinus or grinding | Depends on cause |
| Severe pain with facial swelling | Spreading infection | Urgent care |
The lingering versus brief distinction is the useful one at home. Pain that stops within seconds is usually reversible. Pain that carries on for minutes after the stimulus has gone generally means the nerve is in trouble.
When to go to hospital instead
Most toothache waits until morning safely. These don’t.
- Swelling spreading toward your eye or down your neck
- Difficulty breathing or swallowing
- A fever above 38 degrees alongside dental pain
- Being unable to open your mouth properly
- Pain uncontrolled by over-the-counter medication
- Confusion or feeling generally very unwell
Those point to infection spreading beyond the tooth. Go to the nearest emergency department rather than waiting for a dental appointment.
Preventing the next one
Nearly every night-time toothache has a history. Something was developing for months while nothing hurt.
Decay doesn’t produce pain until it reaches the nerve, by which point the simple filling stage has passed. Regular checkups and X-rays catch it at the stage where treatment is quick and quiet, which is the whole argument for preventive dental care.
Cleaning between teeth daily matters too, since decay between teeth is both common and invisible without X-rays. Professional dental cleanings handle what brushing can’t reach.
And if you grind at night, that pressure can cause cracks that ache without any decay present at all.

Frequently asked questions
Why does toothache get worse at night?
Lying flat increases blood flow to the head, which raises pressure inside an inflamed tooth. There are also fewer distractions, so the pain gets your full attention. Sleeping propped up addresses the first part directly.
Will the pain go away on its own?
It sometimes stops, which is misleading rather than reassuring. Pain ending suddenly often means the nerve has died, while the infection underneath continues and can develop into an abscess. Get it examined either way.
Do I need antibiotics for a toothache?
Usually not. Antibiotics treat spreading infection, not the inflamed nerve causing most toothache. They’re prescribed when there’s swelling or systemic signs, alongside treatment of the tooth itself rather than instead of it.
Is a cold compress better than heat?
For dental pain, yes. Cold reduces blood flow and swelling and numbs the area. Heat increases circulation, which raises pressure and can encourage infection to spread through the tissues.
How quickly can I be seen with severe pain?
Call first thing and describe the symptoms clearly. Practices generally keep time aside for urgent cases, and being specific about swelling, fever or sleep disruption helps the team judge how soon you need an appointment.
Conclusion
Prop your head up, use over-the-counter pain relief as directed, rinse with warm salt water and apply cold to the outside of your cheek. Those measures manage a night, and the tooth still needs diagnosing in the morning. Swelling, fever or trouble swallowing means hospital rather than waiting.
