Toothache at Night: 5 Safe Steps, Sleep Tips, and Red Flags
Toothache at night feels worse because lying down sends more blood to your head and the quiet leaves nothing to distract you. Decay, infection, a cracked tooth or grinding are the usual causes. Tonight, rinse with warm salt water, take pain relief only as the label directs, hold a cold pack to your cheek and prop your head up. Call a dentist if red-flag signs appear.
TL;DR:
- For temporary relief, rinse with warm salt water, floss gently, apply a cloth wrapped cold pack, elevate your head, and avoid chewing on that side.
- Use paracetamol or ibuprofen only as the label directs; ask a pharmacist or doctor first if you are pregnant, take medicines, or have health conditions.
- Swelling that spreads, fever, pus, unrelieved severe pain, or a loose tooth after injury warrants emergency care; call emergency services for breathing or swallowing trouble.
- Antibiotics are reserved for infections that spread beyond the tooth; root canal therapy treats infected pulp, while an unsalvageable tooth may need extraction.
- Pain affecting several upper teeth alongside a blocked nose may come from sinus pressure rather than a dental problem, especially when it eases upright.

Why does tooth pain feel worse when you lie down at night?
Two things change when you get into bed. First, lying flat lets more blood flow to your head. Inside a tooth, the nerve sits in a small, rigid space, so even a slight rise in pressure can turn a dull ache into a throb. Second, the day’s distractions disappear. With no work, noise or conversation to occupy your mind, you notice every pulse of pain.
The underlying cause still matters most. The source of tooth pain may be dental decay, a cracked tooth, or an infection, and each can flare after dark. Common culprits include:
- A deep cavity that has reached the pulp, the soft tissue inside the tooth
- A cracked tooth or a filling that is failing
- An erupting or impacted wisdom tooth
- Pulpitis, which is inflammation of the pulp
- An abscess, a pocket of infection at the root
Grinding is another night-time suspect. If you wake with a sore jaw, or your teeth look flattened or worn, you may clench in your sleep. That sustained pressure can bruise the ligament around a tooth and leave it aching by morning.
Not every toothache starts in the tooth. Sinusitis and a blocked nose can press on the roots of your upper back teeth, and that ache often peaks when you lie down. If several upper teeth hurt at once and you have a stuffy nose, your sinuses may be involved.
Late-night snacks can also add fuel. Hot drinks, ice cream, acidic fruit or lollies can set off sensitive teeth just as you are trying to settle. Our page on sensitive teeth causes and treatment explains why some teeth react so strongly.
What can you safely do at home tonight?
The aim is simple: calm the pain and protect the area until you can see a dentist. Try these steps in order:
- Rinse gently with warm salt water. Follow your dentist’s advice on how to prepare and use a rinse.
- Floss carefully around the sore tooth to remove trapped food, and avoid poking the area with a toothpick or fingernail.
- Hold a cold pack wrapped in a cloth against your cheek for a short time, then remove it. Repeat as needed.
- Prop your head up on extra pillows to ease the pressure.
- Avoid chewing on the painful side, and skip anything hot, cold or sugary.
Over-the-counter medicines can offer temporary relief until you can get specialist care. Paracetamol and ibuprofen are the common choices. Follow the product label for the dose and the gap between doses, and check with a pharmacist or doctor if you have any health conditions, take other medicines, or are pregnant. Never place an aspirin tablet directly against your gum, as it can burn the tissue.
If a filling or crown comes out, keep the piece in a clean container, rinse your mouth gently and avoid chewing on that tooth. Our guide on what to do when a filling falls out covers the first few hours in more detail.
Pro Tip: Before you call the dentist, jot down when the pain began, how severe it feels, and whether you have any swelling or a fever. It helps the team triage you faster.
How can you sleep with a toothache?
Rest helps your body cope, so it is worth trying a few practical tactics:
- Sleep with your head raised on two or three pillows so blood does not pool around the sore tooth.
- Time your pain relief so it is working when you lie down, following the label’s dose and spacing, and never doubling up.
- Give your mind something else to hold: slow breathing, a podcast, or steady white noise such as a fan.
- Use a numbing gel only if the pack allows it. Skip it for young children, and avoid it if you have had an allergic reaction to similar products.
None of these fixes the cause, but they can buy you a few hours of sleep while you arrange care.
When is a toothache at night an emergency?
Toothache can have different causes, and this article cannot determine whether it is safe to wait. Seek immediate emergency care if you have concerning symptoms, and contact a dentist for assessment.
- Facial or neck swelling that is spreading
- Fever alongside tooth pain
- Difficulty breathing or swallowing
- Severe pain that nothing eases
- Pus, a bad taste or a draining bump on the gum
- A loose tooth after a knock or fall
If breathing or swallowing is affected, call emergency services straight away. For concerning symptoms, seek immediate emergency care. Our emergency dentist page explains how to reach us and what to expect at an urgent visit.
When you call, tell the team when the pain started, whether you have a fever or swelling, any antibiotics you are already taking, and which pain relief you have used. That detail helps them judge how quickly you need to be seen.
What will a dentist do about your toothache?
Expect a few clear steps. We start by asking about your symptoms, then examine your mouth, take a dental X-ray, and may tap on the tooth or test it with cold to see how the nerve responds.
Treatment depends on what we find:
- A filling for decay
- Repair of a fractured tooth
- Root canal therapy for an infected pulp
- Extraction when a tooth cannot be saved, including some problem wisdom teeth
A root canal is the definitive treatment when the pulp is infected or inflamed, and it can relieve pain while saving the tooth when appropriate. Antibiotics are only needed when infection has spread beyond the tooth. To keep you comfortable, we can use local anaesthetic and temporary dressings, then plan follow-up care.

How can you tell a toothache from other facial pain?
Not all pain around the mouth comes from a tooth. A few clues can help you tell the difference, though only an examination can confirm it.
Tooth pain usually points to one spot. It often worsens with hot, cold or sweet foods, or when you bite down, and you can usually find the tooth that reacts. The pain tends to throb or ache and may spread to the ear or jaw.
Jaw joint problems feel different. Pain in the joint in front of your ear, clicking or popping, and a jaw that tires or locks when you chew all point to a temporomandibular (TMJ) disorder. These problems are often linked with clenching. Clinical overviews describe how TMJ problems, sleep apnoea and airway issues connect with night-time jaw pain and grinding.
Nerve-related pain, such as trigeminal neuralgia, tends to feel like sudden, sharp, electric jolts. A light touch to the cheek, brushing your teeth or a breeze on your face can set it off, and the attacks usually last seconds to minutes. No single tooth explains it.
Sinus pain affects several upper teeth together, often with pressure behind the cheeks, a blocked nose or pain that eases when you stand up.
If you cannot tell which type you have, that is a good reason to book a check. Treating the wrong problem wastes time while the real cause carries on.
Can a dry mouth make toothache worse at night?
Saliva is your mouth’s built-in defence. It washes away food, neutralises acids and helps protect enamel. During sleep your saliva flow naturally drops, and if you breathe through your mouth, snore or take certain medicines, your mouth can become even drier.
A dry mouth can raise your risk of decay, and decay is a common starting point for tooth pain. It can also leave exposed areas of tooth feeling more sensitive, because there is less saliva to buffer acids and cushion the surface. A tooth that was only mildly irritated during the day can feel much worse during the night.
Some simple habits can help:
- Sip water before bed and keep a glass beside you
- Avoid alcohol-based mouthwashes in the evening, as they can dry the mouth further
- Skip sugary or acidic drinks before sleep
- Treat a blocked nose so you can breathe through it
- Mention any long-term dry mouth to your dentist or doctor, as some medicines are a common cause
If you wake with a parched mouth most mornings, or you snore heavily, it is worth raising at your next visit. It may be part of a bigger picture that affects both your teeth and your sleep.
How can you prevent toothaches at night in the long run?
Most night-time toothaches start as small problems that went unnoticed. Catching them early is the best protection.
Brush twice a day with fluoride toothpaste and clean between your teeth daily. Plaque left behind feeds decay, and decay is one of the most common reasons for tooth pain. Pay extra attention to the gumline and to the back teeth, which are easy to miss.
Look at what you eat and drink, too. Frequent sugary snacks and acidic drinks keep your teeth under attack all day. Try to keep sweet treats to mealtimes, and rinse your mouth with water afterwards. Avoid grazing in the hours before bed.
If you grind your teeth, a mouth guard can protect them from the pressure. We offer mouth guards.
Regular check-ups and cleaning matter most of all. A routine dental exam lets us spot early decay, worn fillings and cracks before they wake you at night. Many problems are quick and simple to fix when found early, but become painful and costly once they reach the nerve. Booking regular check-ups, or following the schedule we advise for you, is a useful step you can take.
Clinician note: you do not have to get through the night alone
A sleepless night with tooth pain is exhausting, and it is not something you have to put up with. A dentist can assess the cause and discuss treatment. If you notice swelling, fever or trouble breathing or swallowing, call for urgent help straight away. For persistent pain, reach out early, and check our website for after-hours contact details.

FAQ
Why do my teeth ache more at night?
Lying down increases blood flow to your head, which raises pressure inside an irritated tooth. With fewer distractions at night, you also notice the pain more. The underlying cause is usually decay, a crack, infection or grinding.
Can a salt water rinse help a toothache?
A warm salt water rinse can soothe the area and wash out trapped food, which may ease mild discomfort. It does not treat the cause. If the pain continues, see a dentist for evaluation and treatment.
How can I sleep with a tooth infection?
Raise your head on extra pillows, take pain relief as the label directs, and use white noise or breathing exercises to settle your mind. A tooth infection needs a dentist, so book urgent care. Go to emergency care if swelling spreads or you struggle to breathe or swallow.
When should I see a dentist for a toothache?
See a dentist if the pain persists, wakes you at night, or comes with swelling, fever or a bad taste. Severe pain or swelling calls for an urgent appointment.
