The 10-second rule
Tooth problem → dentist. Airway, spreading infection, or trauma beyond the teeth → ER. Hospitals don't fix teeth; dentists don't manage life-threatening swelling. During office hours call us at (613) 491-3300 for same-day care; after hours, the Ottawa Dental Society Emergency Service is 613-523-4185.
Why the ER Usually Can't Help Your Tooth
Ontario hospital ERs are staffed for medical emergencies — and almost none have a dentist, a dental chair or dental x-ray equipment. For a toothache or broken tooth, the typical ER visit ends with painkillers, possibly antibiotics, and the advice to see a dentist — after a multi-hour wait. The tooth still needs the dentist it needed at the start.
Go to the Dentist (Same Day) For:
- Severe toothache — usually an inflamed or infected nerve; definitive fix is a root canal or extraction, both dentist territory
- Knocked-out or loosened tooth — a dentist can often re-implant within 30–60 minutes; an ER generally cannot
- Broken, cracked or chipped teeth
- Lost fillings or crowns
- Dental abscess without facial spread — a localized gum "pimple" or swelling confined near the tooth
- Bleeding after an extraction that's oozing but controllable with pressure
- Wisdom tooth flare-ups and food-trap infections
We reserve same-day emergency appointments for new and existing patients — the entire visit, x-ray to treatment, typically takes less time than an ER triage line. How our emergency visits work →
Go to the ER (or Call 911) For:
- Swelling affecting breathing or swallowing, a muffled "hot potato" voice, or inability to open your mouth — dental infections can spread toward the airway, and this is genuinely life-threatening
- Rapidly spreading facial swelling — especially reaching the eye or neck — or dental infection with high fever and feeling very unwell
- Uncontrolled bleeding that doesn't slow with 20 minutes of firm pressure
- Facial or jaw trauma — possible fracture, a blow with loss of consciousness, or injuries beyond the teeth
These are medical emergencies where a hospital's airway management, IV antibiotics and imaging matter. Go. The tooth can be fixed later — we'll handle that part once you're safe.
The Grey Zone: Bad Pain at 2 A.M.
Pain alone — even severe — without swelling or fever is miserable but rarely dangerous overnight. Take over-the-counter pain relief as directed (ibuprofen and acetaminophen can be alternated), keep your head elevated, use a cold compress, and call us at opening. If you can't wait, the after-hours line (613-523-4185) exists for exactly this. And read our tooth pain at night guide for why nighttime makes it worse.
