Dental Emergencies in Canada: What to Do
Dental emergencies can happen anywhere—on the ice, at work, or at home. Quick, calm action can save a tooth and prevent infection. This guide gives step-by-step first aid for common problems, explains when to seek urgent care, and shares prevention tips that cut your risk.
What should I do in a dental emergency?
Stay calm and call a dentist. For a knocked‑out adult tooth, rinse gently, place it back in the socket, or store it in milk, and seek care within 30 minutes. Use gauze for bleeding and a cold compress for swelling.
First, decide if it’s urgent
Get immediate help if you have severe pain, facial swelling, a fever, trouble breathing or swallowing, a knocked-out adult tooth, uncontrolled bleeding, or a jaw injury. Call your dentist or a 24/7 emergency line. If you have trouble breathing, heavy bleeding that won’t stop, or head/neck trauma, call 911 or go to the nearest emergency department.

Knocked-out tooth (avulsed tooth)
What to do, step by step
Time matters. A knocked-out adult tooth has the best chance of survival if it’s put back in place within 30 minutes.
1) Find the tooth. Pick it up by the crown (the white chewing part). Don’t touch the root (the yellowish end).
2) If dirty, gently rinse with milk or saline. Don’t scrub. Don’t use soap or tap water.
3) Try to reinsert it. Gently push it into the socket. Bite on clean gauze to hold it in place.
4) If reinsertion isn’t possible, keep it moist in cold milk, saline, or your cheek. Don’t let it dry out.
5) See a dentist immediately.
Note: Do not reinsert a baby tooth.

Severe toothache
Calm the pain without making it worse
1) Rinse with warm salt water (½ teaspoon salt in a cup of warm water).
2) Floss gently to remove trapped food.
3) Use a cold compress on the cheek for 10 minutes on, 10 minutes off.
4) Take an over-the-counter pain reliever as directed (ibuprofen or acetaminophen). Don’t place aspirin on your gums—it can burn tissue.
Call your dentist if pain is severe, lasts more than 24–48 hours, or you notice swelling, fever, or a pimple on the gum (possible abscess, which is an infection).
Chipped or broken tooth
Protect the area and reduce sensitivity
1) Rinse your mouth gently with warm water.
2) Save any broken pieces in milk if you can.
3) Cover sharp edges with dental wax or sugarless gum to avoid cutting your tongue or cheek.
4) Use a cold compress for swelling.
5) Eat soft foods and avoid chewing on the injured side until repaired.
Call your dentist soon. Small chips may be smoothed or bonded. Larger breaks may need a crown. If the nerve (pulp) is involved, a root canal could be required to save the tooth.
Lost filling or crown
Temporary steps until you’re seen
1) Rinse your mouth gently.
2) If a crown comes off, clean it, try it in gently to confirm orientation, and use temporary dental cement (from a pharmacy) to hold it in place until your appointment.
3) If you can’t re-seat a crown, keep it safe and bring it to your dentist.
4) For a lost filling, place a small piece of sugarless gum or temporary filling material into the cavity to protect the area.
Avoid sticky and hard foods, and schedule a repair as soon as possible to prevent further damage or decay.
Soft tissue injuries (lip, cheek, tongue)
Control bleeding and prevent infection
1) Apply firm pressure with clean gauze for 10–15 minutes.
2) Use a cold compress to limit swelling.
3) If bleeding doesn’t slow within 15–20 minutes, or the cut is deep or gaping, seek urgent care.
Something stuck between teeth
Remove it safely
Gently floss to lift debris out. Don’t use pins, toothpicks, or anything sharp—they can cut the gums or chip enamel. If flossing fails and you’re uncomfortable, call your dentist.
Possible infection or abscess
Watch for warning signs
A dental abscess (a pocket of infection) can spread. Signs include constant throbbing pain, facial swelling, fever, bad taste, or a pimple on the gum. This needs prompt dental care. Don’t try to pop a gum pimple. Use cold compresses and pain relievers as directed, and call your dentist or seek urgent care the same day.
When to go to the ER instead of the dentist
Head or neck trauma, broken jaw, deep cuts that won’t stop bleeding, difficulty breathing, or swelling that threatens your airway require emergency medical care (call 911). For most tooth-related problems, a dentist is the best first call. For a clear, handy checklist and timing tips, see step-by-step first aid for dental emergencies.

Pain and swelling: what helps
Use a cold compress on the outside of your face for 10 minutes on and 10 minutes off. Take over-the-counter pain relievers as directed. Avoid heat on the face—it can worsen swelling. Don’t apply aspirin directly to gums or teeth.
Prevention tips that really work
Protect your teeth before trouble starts
– Wear a mouthguard for hockey, ringette, lacrosse, and other contact sports. A custom guard fits best and protects more.
– Don’t chew ice, pens, or hard candies.
– Keep up daily brushing with fluoride toothpaste and flossing to prevent decay that can turn into emergencies.
– See your dentist regularly for checkups and cleanings to catch small problems early.
– If you grind your teeth (bruxism), ask about a night guard to prevent cracks and breaks.
Build a simple home emergency kit
Keep these items in one place at home and when travelling: clean gauze, small container with lid, saline or contact lens solution, a small carton of shelf-stable milk, over-the-counter dental cement, sugarless gum, a cold pack, and your dentist’s phone number.
Conclusion
Dental emergencies are stressful, but a few quick steps can protect your smile. Control bleeding, avoid heat and aspirin on the gums, and get professional help fast—especially for a knocked-out tooth within 30 minutes. Wear a mouthguard, skip hard chewing, and keep up regular checkups to lower your risk. If you’re unsure whether it’s urgent, call your dentist—better safe than sorry.
FAQ
Is a knocked-out baby tooth an emergency?
It’s urgent to call your dentist, but do not reinsert a baby tooth. Reinserting can harm the adult tooth under the gum. Your dentist will assess the area and advise on next steps.
Should I go to the ER or the dentist?
Go to the ER for heavy bleeding that won’t stop, head or neck injury, trouble breathing, or severe facial swelling. For most toothaches, lost fillings, broken teeth, and knocked-out teeth, call a dentist first and follow the first-aid steps above.
What pain reliever is best for tooth pain?
Over-the-counter ibuprofen or acetaminophen can help. Follow the label or your pharmacist’s advice. Don’t place aspirin on the gums—it can burn tissues. If pain is severe or lasts beyond 24–48 hours, call your dentist.
What if I break a tooth while travelling?
Rinse gently, cover sharp edges, and avoid chewing on that side. Use a cold compress for swelling. Contact a local dentist for urgent repair. Keep your home emergency kit in your carry-on for easy access.
How long do I have to save a knocked-out tooth?
The sooner the better. Aim for reinsertion within 30 minutes. Keep the tooth moist in milk or saline, or reinsert it if you can. Handle it by the crown, not the root.
What should be in a dental emergency kit?
Clean gauze, small lidded container, saline or contact solution, shelf-stable milk, temporary dental cement, sugarless gum, a cold pack, and your dentist’s phone number. These basics help you protect the tooth and tissues until you’re seen.
