Toothache at night usually gets worse because lying down increases pressure in the head and inside an inflamed tooth, and because nothing distracts you from the pain. Raising your head, taking a suitable painkiller, avoiding hot or cold food and rinsing gently can help until morning. Pain that wakes you is a sign to see a dentist soon, and swelling or fever need urgent care.
Why does toothache get worse at night?
- Lying flat: when you lie down, more blood flows towards the head. Inside a tooth with an inflamed nerve there is no room to swell, so the extra pressure is felt as throbbing.
- Fewer distractions: during the day, work, conversation and noise compete for your attention. At night the pain has your full attention.
- Grinding and clenching: many people clench or grind their teeth during sleep without knowing it, which loads a sensitive tooth.
- Painkillers wearing off: a dose taken in the evening may stop working in the middle of the night.
Pain that starts on its own at night, without any trigger, is a classic sign that the nerve inside the tooth is irreversibly inflamed. Our article on the inflamed tooth nerve explains what that means.
The most common causes of night-time toothache
- Deep decay reaching the nerve
- A cracked tooth or a broken filling
- An abscess at the root tip, often with pain on biting
- An erupting or inflamed wisdom tooth
- Gum infection around a tooth
- Sinus congestion, which can make several upper back teeth ache at once, especially when lying down
- Grinding at night, which causes morning jaw ache and tender teeth
How to relieve toothache at night until you can see a dentist
- Sleep with your head raised on an extra pillow to reduce pressure and throbbing.
- Take a suitable over-the-counter painkiller, following the package dose, and if allowed, time it shortly before bed so it covers the first hours of sleep. Ask a pharmacist if you take other medicines or have a medical condition.
- Avoid very hot, very cold and sweet food and drinks in the evening.
- Rinse gently with warm salt water to clean the area, especially if food is stuck.
- Clean carefully around the tooth with a soft brush and floss: trapped food can cause surprising pain.
- Place a cold compress on the cheek for 10 to 15 minutes if there is swelling or throbbing.
- If the pain is relieved by cold water, keep a glass of cool water nearby and sip as needed; this is temporary relief, not treatment, and suggests advanced inflammation.
Things to avoid: placing aspirin or crushed tablets on the gum (it burns the tissue), applying heat to the face, alcohol as a “painkiller”, and taking more painkillers than the recommended dose.
Do antibiotics help night-time toothache?
Usually not. Most night-time toothache comes from an inflamed nerve, which antibiotics do not treat. They are only useful if the infection spreads, with swelling or fever. Our article on antibiotics for a tooth infection explains why self-medicating can delay proper treatment.
When is night-time toothache an emergency?
Seek urgent care the same night or early the next morning if you have:
- Swelling of the face, cheek or under the jaw
- Swelling near the eye or under the tongue
- Fever or feeling very unwell
- Difficulty swallowing, breathing or opening your mouth
- Severe pain after an injury to the mouth
These signs suggest an infection that is spreading or a serious injury. If none of these is present, call your dentist in the morning. Our guide on severe toothache gives more first steps.

Frequently asked questions
Why does my tooth only hurt at night?
Lying down increases pressure inside an inflamed tooth, and you are less distracted at night. Some people also clench or grind during sleep. A tooth that hurts mainly at night often has an inflamed nerve or a crack, and it should be examined even if it is calm during the day.
Can I go to sleep with a toothache?
Yes, if the pain is manageable and you have no swelling, fever or difficulty swallowing or breathing. Raise your head, take a suitable painkiller and avoid hot, cold and sweet food. Book a dental appointment for the next day. If any warning sign appears, seek urgent care instead of waiting.
Can sinus problems cause toothache at night?
Yes. The roots of the upper back teeth lie close to the maxillary sinuses. When the sinuses are congested, for example with a cold or allergy, several upper teeth can ache, especially when you lie down or bend forward. If the pain affects one tooth only, or persists after the sinus problem clears, a dental cause is more likely.
Is it normal for toothache to stop and then come back?
Toothache often comes in waves, especially when a nerve is inflamed. Pain that suddenly disappears after a period of strong pain can mean the nerve has died, which can lead to infection later. Recurring or disappearing pain both deserve an examination.
What should I tell the dentist when I call?
Describe where the pain is, how long it lasts, what triggers it, whether it wakes you up, whether it is worse when biting or with hot or cold, and whether there is any swelling or fever. This helps the clinic judge how urgently you need to be seen.
