A dental emergency does not give you a warning. One minute you are biting into something at dinner, and the next you are holding a cracked tooth in your hand wondering what to do. In those first few moments, most people freeze – because nobody teaches you what to do when a dental emergency happens.
What you do in the first 30 to 60 minutes often determines whether a tooth can be saved, whether an infection spreads, and how much treatment you will ultimately need. This guide gives you clear, actionable steps for the most common dental emergencies so that when the moment comes, you know exactly what to do – and when to call us for same-day emergency care.
How to Identify a Dental Emergency
Not every dental concern requires an emergency appointment, but some absolutely do. Knowing the difference helps you respond with the right level of urgency.
A situation is a dental emergency when any of the following apply:
- Uncontrolled bleeding that does not slow after 10 to 15 minutes of firm pressure
- Severe, throbbing pain that is not relieved by over-the-counter pain medication
- A knocked-out permanent tooth – time is critical here, as reimplantation success drops sharply after one hour
- Significant swelling in the jaw, face, or neck, especially if it is spreading or making it difficult to swallow or breathe
- A broken tooth with exposed nerve causing sharp sensitivity to air, temperature, or pressure
- A suspected dental abscess – a visible pimple-like bump on the gum, fever, or foul taste
- A lost crown or filling leaving a tooth exposed and painful
If you are in pain and unsure, call our emergency dental care line. Our teams across Milton, Mississauga, and Brampton are available to assess your situation and get you in for same-day treatment when needed.
Common Dental Emergencies and First Aid Steps
Each type of dental emergency calls for a different immediate response. Here is what to do for the situations we see most often.
Knocked-Out Tooth
A knocked-out tooth – called an avulsed tooth – is one of the few dental emergencies where minutes genuinely matter. With the right first aid and fast care, there is a real possibility of saving the tooth entirely.
Follow these steps immediately:
- Pick up the tooth by the crown – the white part you can see – never by the root. The root contains delicate ligament cells that must stay intact for reimplantation to work.
- If the tooth is dirty, rinse it gently with clean water. Do not scrub it, wrap it in a cloth, or let it dry out.
- Try to reinsert it into the socket if possible. Hold it in place by gently biting on a clean piece of gauze or cloth. This is the best storage option.
- If reinsertion is not possible, store the tooth in a small container of cold milk, or hold it between your cheek and gum on the way to the dentist. Do not store it in water.
- Get to an emergency dentist within 30 minutes. Every minute counts. Contact our offices immediately.
Note that this advice applies to permanent teeth only. A knocked-out baby tooth should not be reimplanted, as doing so can damage the developing adult tooth underneath. Call us and we will advise you on next steps.
Broken or Cracked Tooth
A broken tooth can range from a minor chip with no pain to a severe fracture that exposes the inner pulp of the tooth. The right response depends on the severity.
- Rinse your mouth with warm water to clean the area.
- Save any pieces of the tooth if you can find them and bring them to your appointment.
- Apply a cold compress to the outside of your cheek to reduce swelling if the break is causing facial swelling.
- Take an over-the-counter pain reliever as directed on the label if you are in pain. Do not place aspirin directly on the gum or broken tooth – this can cause a chemical burn to the soft tissue.
- Cover sharp edges with temporary dental wax or sugar-free gum to protect your tongue and cheek until you can be seen.
A small cosmetic chip may be able to wait a day or two for a regular appointment. But if you have pain, sensitivity, or a large piece of tooth has broken off, treat this as an emergency and contact us for same-day care.
Severe Toothache
A severe toothache is your body’s way of telling you something is seriously wrong. It should never be dismissed or masked with pain medication and left untreated for days.
- Rinse with warm saltwater to reduce inflammation and clear any debris around the tooth.
- Use dental floss gently to check whether something is lodged between teeth causing the pain. Sometimes a trapped piece of food is the culprit.
- Take ibuprofen or acetaminophen as directed to manage pain while you arrange to be seen.
- Apply a cold compress externally to reduce swelling. Do not apply heat to the outside of your jaw – it can worsen swelling and pain.
- Avoid extremely hot, cold, or sweet foods and drinks that may intensify the pain.
If the pain is severe, constant, or accompanied by swelling and fever, this may indicate a dental abscess – which requires urgent care. Do not wait for the pain to pass on its own.
Lost Filling or Crown
Losing a filling or crown is uncomfortable and can leave a tooth vulnerable to further damage, but it is rarely dangerous. Here is what to do while you wait for your appointment:
- Locate the crown if you can and keep it safe. In some cases, your dentist may be able to re-cement it.
- Rinse the inside of the crown with water. If you are going to attempt to temporarily reattach it, you can use a small amount of dental cement (available at most pharmacies) or even toothpaste as a short-term fix.
- Do not use super glue. This seems obvious, but it is worth saying – super glue is not safe to use in your mouth and can damage the tooth and crown.
- Avoid chewing on that side of your mouth until the crown or filling is properly restored.
- If the exposed tooth is sensitive, clove oil applied with a cotton swab can provide temporary relief – it is a natural analgesic that dentists have used for generations.
A lost filling or crown should be addressed within a day or two. The exposed tooth can decay quickly and the underlying structure may shift.

Dental Abscess
A dental abscess is a pocket of infection that forms inside the tooth or in the gum. This is one of the most serious dental emergencies because the infection can spread beyond the mouth to the jaw, neck, or even the bloodstream if left untreated.
Signs of a dental abscess include:
- A severe, persistent toothache that may radiate to your jaw, neck, or ear
- Swelling in your cheek or jaw
- A pimple-like bump on the gum near the affected tooth
- Fever or a general feeling of being unwell
- A sudden rush of foul-tasting fluid followed by pain relief – this can indicate the abscess has ruptured
First aid steps for a suspected abscess:
- Rinse with a mild saltwater solution several times a day to draw out some of the infection and relieve discomfort.
- Take over-the-counter pain relievers as directed.
- Do not attempt to pop or drain the abscess yourself – this risks spreading the infection.
- Contact us immediately for emergency care. If you develop difficulty swallowing, breathing, or the swelling is spreading to your neck, proceed to the emergency room rather than waiting for a dental appointment.
Bleeding That Won’t Stop
Some bleeding after a tooth extraction is normal, but prolonged bleeding – or bleeding that starts suddenly without an obvious cause – requires attention.
- Apply direct pressure with a clean piece of gauze or a folded clean cloth. Bite down firmly and hold for 15 to 20 minutes without checking underneath, as lifting the gauze disrupts clot formation.
- Avoid rinsing vigorously, spitting, or drinking through a straw – these actions can dislodge the clot.
- Do not take aspirin for pain if you are trying to stop bleeding – aspirin thins the blood and will make things worse. Use acetaminophen instead.
- Keep your head raised – lying flat increases blood pressure to the area. Rest with your head propped up on a pillow.
- If bleeding does not slow after 30 to 45 minutes of sustained pressure, contact us or proceed to an emergency room, especially if you are on blood thinners or have a known bleeding disorder.
When to Go to the ER vs. an Emergency Dentist
This is a question we hear often, and the answer matters. Most dental emergencies are best handled by an emergency dentist – not a hospital emergency room. ER physicians are not trained in dental procedures and generally cannot treat the underlying dental problem. They can prescribe antibiotics and pain medication, but that is typically the extent of it.
Go directly to a hospital emergency room when:
- You have difficulty breathing or swallowing – this can indicate a spreading infection that is affecting your airway
- Facial swelling is severe and spreading rapidly, particularly toward the neck or floor of the mouth
- You have been in a trauma that may have caused jaw fracture or head injury alongside the dental damage
- You have a high fever alongside dental pain and facial swelling
- Bleeding is completely uncontrolled and not responding to pressure
Call or visit an emergency dentist when:
- A tooth has been knocked out
- You have severe, unrelenting tooth pain
- A tooth is cracked or broken with nerve exposure
- You have a dental abscess without the severe systemic symptoms listed above
- A crown or filling has come out and left the tooth exposed and painful
- You have localized swelling in the gum area
Our emergency dental care teams at The Dental Team offer same-day appointments at our locations across the Greater Toronto Area. Call us before heading to the ER – in most cases, we can see you faster and treat the actual problem.
What to Bring to Your Emergency Dental Appointment
Arriving prepared helps us treat you faster. Here is what to bring:
- The tooth or tooth fragment, stored properly as described above
- A list of any medications you are taking, including blood thinners, aspirin, diabetes medications, or immunosuppressants – these affect treatment options
- Your dental insurance information if you have it, though we will treat the emergency regardless
- Information about any allergies, particularly to antibiotics or local anesthetics
- A description of when the pain started, what triggered it if anything, and whether it is constant or intermittent
- Any dental work you had recently, such as a crown, filling, or extraction – this context helps us diagnose faster
If your child is the patient, bring their health card and any allergy information. Our teams are experienced in treating pediatric dental emergencies and will work to keep the experience as calm as possible for both of you.
How to Prevent Common Dental Emergencies
You cannot prevent every accident. But many of the dental emergencies we treat could have been avoided – or at least reduced in severity – with a few consistent habits.
- Wear a mouthguard during sports. A custom-fitted sports guard is one of the most effective protections against knocked-out and broken teeth. This applies to adults and children in hockey, basketball, soccer, martial arts, and even cycling.
- Do not use your teeth as tools. Opening packages, cracking nuts, or biting your nails all create micro-fractures over time. One of those micro-fractures eventually becomes a full break – usually at the worst possible moment.
- Address small problems before they become big ones. A minor cavity that you delay treating can become an abscess. A slightly loose crown you ignore can fall off unexpectedly. Regular dental cleanings and checkups catch these problems early, when treatment is simpler.
- Wear a night guard if you grind your teeth. Bruxism causes significant wear and makes teeth more vulnerable to cracking. A custom night guard distributes pressure and prevents this damage from accumulating.
- Be cautious with hard and sticky foods. Hard candies, ice, popcorn kernels, and sticky candies are common culprits in broken and dislodged crowns – especially if you already have older fillings or root canal-treated teeth, which are more brittle.
Prevention is the most cost-effective dental care there is. Treating a knocked-out tooth or a dental abscess costs significantly more – in time, discomfort, and money – than the routine checkup that might have caught the issue early.
Frequently Asked Questions About Dental Emergencies
What counts as a dental emergency?
A dental emergency is any situation involving severe pain, uncontrolled bleeding, significant swelling, a knocked-out tooth, or signs of infection such as fever and abscess. If you are unsure, call us – we will help you assess the situation quickly over the phone.
Can a knocked-out tooth be saved?
Yes, often it can – but time is critical. A permanent tooth that is kept moist and brought to an emergency dentist within 30 to 60 minutes has a realistic chance of successful reimplantation. After two hours, the odds drop considerably. Baby teeth are not reimplanted, but should still be assessed by a dentist.
Should I go to the emergency room for a toothache?
In most cases, no. Hospital ERs can prescribe pain medication and antibiotics, but they cannot perform dental procedures. You are better served by an emergency dentist who can identify and treat the actual cause. Go to the ER if you have difficulty breathing or swallowing, high fever with facial swelling, or signs of a spreading jaw infection.
What is the best way to store a knocked-out tooth?
The best option is to reinsert the tooth into its socket and hold it in place. If that is not possible, store it in a container of cold milk. Do not store the tooth in water and do not wrap it in a dry cloth – drying out damages the root cells needed for reimplantation.
How do I know if I have a dental abscess?
Signs include a severe, throbbing toothache that may radiate to the jaw or ear, visible swelling on the gum or cheek, a pimple-like bump on the gum, fever, and sometimes a sudden release of foul-tasting fluid. Contact an emergency dentist right away – dental abscesses do not resolve on their own and can spread.
Will emergency dental care hurt?
Our goal is to relieve your pain, not add to it. We use local anesthesia for any procedures that require it and work at your pace. Letting the pain continue untreated is far more harmful than getting it addressed right away.
Does the Canadian Dental Care Plan cover dental emergencies?
Coverage under the CDCP varies based on the treatment required. Many emergency services are covered for eligible patients. Our teams can help clarify your coverage when you call, and we welcome patients with and without insurance for emergency care.
