Is a Toothache a Dental Emergency? How to Tell Tonight
Updated October 30, 2026
Reviewed by Dr. Allison Atchison, D.M.D., Camden Dental, Abbotsford, BC
It's 11 pm, a back tooth is throbbing, and your dentist's office closed hours ago. So, is a toothache an emergency? Often it isn't the kind that needs the ER tonight. For many toothaches, HealthLink BC's advice for the evening is to watch your symptoms and call your dentist in the morning [1].
A few signs change that. Swelling in your face with a fever, or any trouble breathing or swallowing, means you get help tonight [2]. Below, you'll see how to tell which group you're in and what to do for the pain overnight. You'll also see when the ER is the right call instead of a dentist.
TL;DR
How long a toothache has lasted is one clue, not the test. BC's checker also weighs pain level, lost sleep, face swelling, fever and health conditions [1].
Trouble breathing or swallowing, swelling into the neck, or facial swelling with fever when you can't reach a dentist means emergency care now [2][6].
If BC's checker says seek care today and it's evening, watch your symptoms and call your dentist in the morning [1].
Overnight: ice on the cheek, a pain reliever taken as labelled, no heat, no pills against the tooth [3][7].
Not sure? 8-1-1 connects you to a registered nurse 24 hours a day [4].
The ER treats infection and pain but doesn't fix teeth, and MSP doesn't cover the dental visit that follows [5][6].
A toothache that fades still needs a dentist [3].
One liner: Many toothaches can wait for a morning call to your dentist, but a short list of signs can't.
Is a Toothache an Emergency?
In short: Duration alone doesn't make it an emergency; swelling, fever, and breathing or swallowing trouble do.
How long a toothache has lasted doesn't decide, on its own, whether it's an emergency. HealthLink BC's toothache checker treats duration as one question among several, and only some answers point to care right away [1].
Is a toothache an emergency? It needs care tonight if it comes with facial swelling and fever, or any trouble breathing or swallowing [2]. Without those signs, it still needs a dentist [3]. If BC's checker says seek care today and it's evening, watch your symptoms and get care in the morning [1].
A rule you'll often see online says any toothache lasting more than a day or two is automatically an emergency. BC's checker asks more than that. It wants to know:
How bad the pain is on a scale of 0 to 10
Whether it has lasted more than 2 days
Whether it's disrupting your sleep or daily activities
Whether you have swelling or pain in your face
Whether you might have a fever
Whether you have diabetes, a weakened immune system, or surgical hardware in the area [1]
Your answers lead to one of five outcomes, from home treatment up to calling 9-1-1. Two toothaches of the same length can get different answers once swelling, fever or lost sleep enter the picture. The next section shows what each outcome means for tonight.
How to Tell Tonight If It Can Wait Until Morning
In short: Find your row in BC's five outcomes. In the evening, "seek care today" means watch your symptoms and call in the morning.
HealthLink BC's toothache checker sorts your answers into five outcomes [1]. Here's what each one means when it's late and your dentist's office is closed.
Outcome | What it means | What to do tonight |
Call 9-1-1 now | You need emergency care | Call 9-1-1 and wait for the ambulance. Don't drive yourself. |
Seek care now | You may need care right away | Call your dentist now. If you can't reach one, seek care within the hour. |
Seek care today | You likely need care soon | In the evening, watch your symptoms and get care in the morning. Go sooner if things get worse. |
Make an appointment | It may not improve without care | Book a dental visit within 1 to 2 weeks and use home treatment while you wait. |
Home treatment | You can likely manage it at home | Use home care, and call if it gets worse or doesn't improve as expected. |
Watching your symptoms overnight means checking for change, not waiting it out no matter what. HealthLink BC lists new or worse redness, warmth, swelling, pus or fever as reasons to call for help. So are symptoms that come more often or feel more severe [1]. If any of those show up at 2 am, move up a row.
Not sure which row fits? Call 8-1-1. HealthLink BC's registered nurses answer 24 hours a day, 7 days a week, and can advise whether you should be seen in person. Its pharmacists are on from 5 pm to 9 am if you have a question about pain medicine [4]. The call is free. For trouble breathing or swallowing, skip the call and get emergency help [2].
If you land in the "seek care today" row, your next step is a call to your dentist as soon as the office opens.
When to Go to the Emergency Room for Tooth Pain Instead
In short: Go for breathing or swallowing trouble or spreading swelling. The tooth still needs a dentist after.
If your question tonight is "can I go to emergency room for tooth pain," the answer is yes. For some signs, you should go without waiting for a dentist. Head to the ER, or call 9-1-1, if you have:
Any trouble breathing or swallowing [2]
Swelling that spreads down into your neck [6]
Swelling in your face with a fever, and you can't reach a dentist [2]
Jaw pain together with chest pain or pressure, sweating, shortness of breath or nausea, which can be signs of a heart attack. Call 9-1-1 [1]
A knocked-out adult tooth and no dentist who can see you right away (bring the tooth with you) [1]
You might picture the ER fixing the tooth. In practice, an emergency doctor treats the danger. They can start antibiotics for an infection and give you pain medicine, but emergency physicians don't pull or repair teeth [6]. The tooth still needs a dentist after you leave.
Cost works differently in BC than many people expect. The Medical Services Plan (MSP) doesn't cover dental services, apart from the limited ones listed under its benefits [5]. So the visit that actually fixes the tooth, whether that's a filling, a root canal or an extraction, falls outside MSP.
That doesn't make the ER the wrong choice. For the signs above, it's the right one. Once the swelling or breathing problem is under control, book the dental visit as soon as you can, so the source of the infection gets treated.
Toothache at Night: What to Do
In short: Ice outside, a pain reliever as labelled, no heat, no pills on the gum.
Once you've ruled out the warning signs, tonight is about comfort until you can reach your dentist. Keep an ice pack and a glass of water by the bed, and work through these steps.
Leave a message if you can. If your dentist has an after-hours line or answering service, describe your symptoms so the office knows to fit you in.
Clear the area. Rinse your mouth with warm water, then floss gently around the sore tooth to remove any trapped food [12].
Use cold on the outside. Hold an ice pack on your cheek for 10 to 15 minutes at a time, with a thin cloth between the ice and your skin [3].
Take an over-the-counter pain reliever. Acetaminophen or ibuprofen can help. Read and follow the label. If you're unsure what's safe with your other medicines, an 8-1-1 pharmacist can help overnight [3][4].
Go easy on food and drink. Skip anything hot, icy or sugary if it makes the pain worse [1].
Numbing gel is for adults. Adults can put an over-the-counter benzocaine gel on the tooth for short-term relief. Ask a doctor before using any mouth-numbing product on a child, since Health Canada warns some can be dangerous [1].
Two things to skip. Don't put heat on your jaw, such as a heating pad or hot water bottle, because heat makes it worse. And don't put a pill against the sore tooth or gum [7]. Aspirin and other painkillers can burn gum tissue [12]. Swallow it as the label directs.
These steps take the edge off. They don't treat the cause, so the morning call to your dentist still matters.
Tooth Pain Relief Until Appointment Day: What Helps and What to Skip
In short: Cold, labelled pain relief and gentle cleaning help. Heat and waiting through warning signs don't.
If your answers point to a booked visit rather than a same-day one, you may be managing pain for days, not hours. HealthLink BC suggests home treatment while you wait for an appointment that could be 1 to 2 weeks away [1]. Here's what's worth doing in that stretch, and what to leave alone.
Item | Helps or skip | Why |
Ice pack on the outside of your cheek | Helps | Eases pain and swelling. Use a cloth, 10 to 15 minutes at a time [3] |
Over-the-counter pain reliever, as labelled | Helps | Short-term relief while you wait [3] |
Toothpaste for sensitive teeth, rubbed on the spot 2 or 3 times a day | Helps | Reduces sensitivity to heat, cold or brushing [1] |
Gentle brushing and flossing every day | Helps | Keeps the area clean without irritating it [1] |
Warm salt-water rinse when you can't brush after eating | Helps | Listed for gum care: 1 teaspoon (5 mL) of salt in 1 cup (250 mL) of warm water [1] |
Heat on the jaw | Skip | Makes the pain worse [7] |
A pill held against the tooth or gum | Skip | Swallow pain relievers as directed instead [7] |
Numbing gel on a child without asking a doctor | Skip | Health Canada warns some can be dangerous [1] |
Waiting it out once swelling, fever or pus appear | Skip | These are signs to call for help [1] |
If the pain fades before your visit, keep the appointment. The next section explains why.
When to See a Dentist for Tooth Pain, Even If It Eases
In short: Pain that fades can hide growing decay or infection, so keep the appointment.
A toothache that stops isn't the same as a problem that's gone. With tooth decay, the pain can go away for a while as the decay keeps growing. An untreated cavity can get worse until the tooth dies [3]. An abscess can do the same. As the infection spreads, the bone around the tooth may start to dissolve, and you may feel less pain even though the infection is still there [8].
Slower signs still deserve a dental visit, and BC's checker asks about each of them [1]:
Sensitivity to hot, cold, sweet or sour that's moderate to severe, or lasts more than a week
A toothache or gum problem that has gone on for more than 2 weeks
Pain or discomfort from a filling, crown or denture
Moderate to severe sensitivity can point to a cracked tooth, a cavity or a lost filling, and treating it can keep the tooth from dying [1]. Depending on the cause, that might mean a filling, an extraction, or root canal therapy. Root canal therapy removes infected pulp from inside the tooth so the tooth can be kept [9].

Quick Answers
In short: Many toothaches can wait for a morning call, but swelling, fever, and breathing or swallowing trouble can't.
What to do if I have a toothache at night?
Hold an ice pack on your cheek for 10 to 15 minutes at a time. Take an over-the-counter pain reliever as the label directs, and avoid food or drink that makes the pain worse [1][3]. Don't use heat, and don't put a pill against the tooth [7]. Call your dentist in the morning.
When is tooth pain an emergency?
Tooth pain needs care right away if it comes with trouble breathing or swallowing, or with facial swelling and a fever when you can't reach a dentist [2]. Swelling that spreads down into your neck is also a reason to go to the emergency room [6].
What usually causes a toothache?
Tooth decay is the most common cause [1]. Other causes include an infection in or around the tooth (an abscess) and a tooth that hasn't broken through the gum. An injury or grinding can also damage the nerve in the centre of the tooth [1]. A dentist can find which one it is.
Can a toothache wait until morning?
Often, yes. When HealthLink BC's checker says to seek care today and it's evening, its advice is to watch your symptoms and get care in the morning [1]. If redness, warmth, swelling, pus or fever show up or get worse overnight, seek care sooner [1].
Can the ER pull a tooth?
An emergency doctor can give you antibiotics for an infection and medicine for the pain, but pulling or repairing teeth isn't part of their job [6]. You'll still need a dentist to treat the cause.
Should I use heat or ice on a toothache?
Ice. Hold an ice pack on the outside of your cheek, with a thin cloth between it and your skin, for 10 to 15 minutes at a time [3]. The Canadian Dental Association advises against a heating pad or hot water bottle on the jaw, because heat makes things worse [7].
Who can I call about a toothache at night in BC?
Call 8-1-1 to reach HealthLink BC. Registered nurses answer 24 hours a day, and pharmacists are available from 5 pm to 9 am [4]. If you have trouble breathing or swallowing, go to the emergency room or call 9-1-1 instead [2]. If your dentist has an answering service, leave a message too.
