What Counts as a Dental Emergency?

A dental emergency is a mouth or tooth problem that needs care the same day: severe pain, a knocked-out or broken tooth, bleeding that will not stop, or signs of infection. The setting depends on the symptoms. Most urgent problems belong in a dental office, but trouble breathing or swallowing, or swelling that is spreading, needs 911 or a hospital first.

Key Takeaways

• A dental emergency is any oral problem where waiting risks losing a tooth, spreading infection, ongoing bleeding or severe uncontrolled pain.
• Call the dental office the same day for severe toothache, a knocked-out permanent tooth, a broken or loose tooth, a suspected abscess or a lost crown that hurts.
• Call 911 or go to the Emergency Department at the Colchester East Hants Health Centre in Truro for difficulty breathing or swallowing, rapidly spreading facial or neck swelling, uncontrolled bleeding or serious facial injury.
• Nova Scotians can call 811 at any hour to speak with a registered nurse when they are unsure which kind of help they need.
• A problem that can wait for a regular appointment still needs to be booked, and it becomes urgent if pain, swelling or fever appears.

What is a dental emergency?

A dental emergency is an injury or condition of the teeth, gums or mouth that needs prompt professional attention to relieve severe pain, stop bleeding, control infection or save a tooth. The defining feature is time: waiting days for a routine visit is likely to make the outcome worse.

Urgency is set by symptoms and risk, not by how dramatic a problem looks. A small cosmetic chip can look alarming but carry little risk, while a quiet swelling under the jaw can be far more serious. A dental emergency also differs from a medical emergency, and knowing the difference tells you where to go first.

Think of three levels:

1. Medical emergency. The airway, breathing, circulation or the whole body is at risk. Call 911 or go to a hospital emergency department.
2. Dental-office urgency. The problem is in the mouth and needs a dentist today or as soon as possible.
3. Routine but important. The problem needs a dentist, but a regular appointment in the coming days or weeks is reasonable if nothing gets worse.

The rest of this guide helps you sort a symptom into the right level.

Dental office or hospital? A quick triage table

The table below summarizes common situations. It is a decision aid, not a diagnosis. When symptoms fit more than one row, follow the most urgent one.

Situation	Call the dental office today	Call 911 or go to the emergency department
Severe toothache	Pain that keeps you awake or does not ease with over-the-counter pain relief	Toothache with trouble breathing or swallowing, or swelling spreading into the neck
Knocked-out tooth	Permanent tooth knocked out: call right away and bring the tooth, kept moist	Knocked-out tooth with head injury, loss of consciousness or heavy bleeding
Broken or cracked tooth	Sharp edges, pain, a loose piece or pink tissue showing	Suspected broken jaw, major facial injury or bleeding you cannot control
Swelling or abscess	Gum swelling, a pimple-like bump, bad taste or mild fever	Swelling closing an eye, under the tongue or down the neck; high fever with feeling very unwell
Bleeding	Bleeding that slows but keeps returning after an extraction	Bleeding that does not stop with firm pressure
Lost filling or crown	Pain, a sharp edge or trouble biting	Rarely a hospital problem on its own
Cut lip, tongue or cheek	A small cut that keeps oozing or a flap of tissue	A deep or gaping wound, or bleeding that will not stop

If you are unsure, calling is better than guessing. A dental office can tell you how soon you should be seen, and 811 can help decide whether hospital care is needed.

Problems that usually need same-day dental care

Dental-office urgency means you should contact a dentist promptly, often the same day, because delay may increase pain, infection risk or the chance of losing a tooth.

Severe or escalating tooth pain

Severe tooth pain that interferes with sleep or daily life often signals a deep cavity, an abscess or a cracked tooth. Pain with swelling, fever or a bad taste deserves a same-day call. Over-the-counter pain relief and a cold compress on the cheek can ease symptoms, but they do not treat the cause. Our guide to toothache causes and relief covers pain that is less urgent.

A knocked-out permanent tooth

A knocked-out permanent tooth is one of the most time-sensitive problems in dentistry. The American Association of Endodontists advises acting within about 30 minutes and seeing a dentist as soon as possible. Handle the tooth by the crown only and keep it moist. Baby teeth are handled differently and are not put back. The steps are in our guide to what to do with a knocked-out tooth.

A loose, displaced or broken tooth

A tooth that is pushed out of position or feels very loose after an injury has damaged its supporting ligament and possibly bone. A dentist may reposition and splint it. A cracked or broken tooth with pain, sharp edges or exposed inner tissue also needs prompt care, because cracks can spread and exposed pulp can become infected.

A suspected dental abscess

A dental abscess is a pocket of bacterial infection at the root of a tooth or in the gum. Signs include throbbing pain, gum or face swelling, a pimple-like bump that may drain, a bad taste and fever. A localized abscess needs timely dental treatment even when hospital care is not required. See our guide to dental abscess signs.

Bleeding that keeps coming back

Bleeding from the mouth after an extraction or injury should slow with firm pressure from clean gauze. Landmark Dental Care's emergency guidance treats bleeding that has not stopped after 10 to 15 minutes of pressure as a reason for immediate care. Bleeding that soaks gauze quickly or will not stop at all is a hospital situation.

A lost filling or crown that hurts

A lost filling or crown is often urgent but not always an emergency. It moves up the list when the tooth is painful, the edge is cutting your tongue, or you cannot bite comfortably.

Soft-tissue injuries

A cut to the lip, cheek, gum or tongue often heals well with pressure and gentle rinsing. A wound that keeps bleeding, gapes open or leaves a flap of tissue may need stitches or other care.

When to call 911 or go to the emergency department

Some situations are medical emergencies first and dental problems second. Call 911 or go to the Emergency Department at the Colchester East Hants Health Centre if you have:

• difficulty breathing, or noisy breathing after a facial injury;
• difficulty swallowing, or you cannot manage your own saliva;
• swelling of the face, under the tongue or down the neck that is spreading or getting worse quickly;
• swelling that is closing an eye;
• bleeding that continues despite firm, steady pressure;
• a suspected broken jaw, major facial injury or any loss of consciousness;
• high fever with confusion, marked weakness or feeling severely unwell;
• a tooth or piece of tooth that may have been inhaled, especially a child who is coughing or struggling to breathe.

Hospital teams can protect the airway, control serious bleeding, manage major trauma and start treatment for a spreading infection. They may not complete dental repair. After a hospital visit, follow up with a dentist so the tooth or source of infection is treated.

This boundary exists for a reason. A dental office is equipped for most oral urgencies, but airway problems and major trauma need hospital resources. Do not drive yourself if you are struggling to breathe; call 911.

What can wait for a regular appointment

Not every dental problem is an emergency. These issues often fit a routine or soon-scheduled visit:

• mild, brief sensitivity to cold that settles within seconds;
• a tiny enamel chip with no pain, no sharp edge and no change in your bite;
• staining or cosmetic concerns without pain or swelling;
• a lost filling or crown with no pain and no sharp edge;
• food catching around a crown or bridge without pain or swelling;
• a loose orthodontic retainer wire that is not stabbing your cheek and can be covered with orthodontic wax (call your orthodontist).

"Can wait" does not mean "ignore." Book soon, and move the visit up if pain grows, swelling appears, pain wakes you at night or you develop a fever. Many dental emergencies begin as small problems that were left alone.

Routine checkups are the main way to prevent emergencies. Regular exams, digital X-rays when indicated and cleanings can catch deep decay or cracked fillings before they cause pain. Keeping up with those visits is the simplest way to avoid an urgent call later.

What to do while you wait to be seen

While you arrange care, focus on safety and comfort, not home diagnosis.

1. Call promptly. Explain the main symptom, when it started and any red-flag features.
2. Control bleeding. Press clean gauze or a clean cloth firmly on the area. If bleeding is heavy or will not stop, seek emergency medical care.
3. Use a cold compress. A cold pack wrapped in a cloth on the outside of the cheek can ease swelling from an injury.
4. Keep the tooth or pieces. Save a knocked-out permanent tooth in milk or saliva, and keep broken pieces in a clean container.
5. Cover sharp edges. Dental wax or orthodontic wax can protect your tongue and cheek for a short time.
6. Eat soft foods and chew on the other side.
7. Do not self-treat. Do not drain a swelling, use superglue, or place aspirin on the gum, which can burn the tissue.

Over-the-counter pain relievers such as ibuprofen or acetaminophen may help some adults when used as the label directs and when they are safe with your health conditions and medications. They reduce symptoms for a while; they do not treat the cause. A pharmacist can tell you which product suits you.

When you call the office, have this ready:

• your name and a callback number;
• whether the problem followed an injury, and how;
• which tooth or area hurts;
• whether there is swelling, fever, drainage or trouble opening your mouth;
• medications you take, allergies and relevant medical history.

Special situations that change the urgency

Children

Children's injuries need a quick call because baby teeth and permanent teeth are treated differently. Tell the team the child's age and which tooth was injured. A knocked-out baby tooth is not put back in, but the child still needs to be checked. In Nova Scotia, the provincial Children's Oral Health Program covers some basic dental care, including fillings and necessary extractions, for children aged 14 and younger with a valid health card.

Pregnancy

Dental pain and infection during pregnancy should not be put off. Tell the dental team you are pregnant and how far along you are. Check with your pharmacist, doctor or midwife before taking any pain reliever.

Medical conditions and medications

Diabetes, a weakened immune system, some heart conditions and blood thinners can all change how quickly a dental infection or bleeding should be seen. Mention these when you call. What would be a next-day problem for one person may be a same-day problem for another.

Older adults and denture wearers

A broken denture or a sore spot under a denture is usually urgent rather than an emergency. Swelling, fever, or a sore that does not heal in about two weeks needs an exam.

Dental anxiety

Fear of the dentist is a common reason people wait until a problem becomes an emergency. Say so when you call. Knowing ahead lets the team explain each step and plan pauses, which often makes an urgent visit easier.

Getting emergency help in Truro and Colchester County

If you live in Truro, Bible Hill or elsewhere in Colchester County, here is how the local options fit together.

When you are unsure, day or night, call 811 to speak with a registered nurse. The nurse can help you decide whether to manage at home, call a dentist in the morning or go to the hospital now.

If your problem starts on an evening or weekend and has no red flags, keep it clean, manage the pain and call the dental office when it opens. If you have questions about coverage, such as the Canadian Dental Care Plan, call the office to confirm current participation and billing before your visit, and see our CDCP page.

FAQ

Is a toothache a dental emergency?

A toothache is a dental emergency when the pain is severe, keeps you awake, or comes with swelling, fever or a bad taste. Call the dental office the same day. If the toothache comes with trouble breathing or swallowing, call 911 instead.

Should I go to the ER for a dental emergency?

Go to the emergency department for breathing or swallowing problems, spreading facial or neck swelling, uncontrolled bleeding or serious facial injury. Most other dental emergencies are treated best by a dentist, because a hospital usually cannot repair the tooth itself.

Is a lost filling a dental emergency?

A lost filling with no pain and no sharp edge is usually urgent but not an emergency, so booking within a few days is often reasonable. Call sooner if the tooth hurts, feels sharp or your bite changes.

What counts as a dental emergency for a child?

A knocked-out, loose or broken tooth, a swollen face or gum, or a toothache that stops a child from eating or sleeping all need a same-day call. A child who is struggling to breathe or may have inhaled a tooth needs 911.

Who do I call for a dental emergency at night in Nova Scotia?

Call 911 or go to the nearest emergency department for any life-threatening symptom. For advice at any hour, call 811 to speak with a registered nurse. Otherwise, call your dental office as soon as it opens.
