Call 905-237-2353 for Emergency Availability
Medical emergency? Call 911 or go to a hospital emergency department for difficulty breathing or swallowing, uncontrolled bleeding, major facial trauma or another potentially life-threatening concern. Do not wait for an online reply.
Call Mackenzie Smiles at 905-237-2353 as soon as you can. Tell us what happened, which tooth is affected, and when the symptoms started. The table below covers the first steps that protect the tooth while you arrange care. If you have difficulty breathing or swallowing, bleeding that will not stop, or a suspected jaw fracture, call 911 or go to the nearest hospital emergency department.
| Problem | What to do now | How urgent |
|---|---|---|
| Knocked-out tooth | Hold the tooth by the crown, not the root. Rinse it briefly without scrubbing, then try to place it back in the socket — or keep it in milk or inside your cheek — and call us right away. | Time-critical: call immediately |
| Severe toothache | Rinse with warm water and use floss gently to remove anything trapped between the teeth. Do not place aspirin directly on the gum. | Call the same day |
| Broken or chipped tooth | Save any pieces, rinse your mouth with warm water, and use a cold compress on the cheek if there is swelling. | Call the same day |
| Lost filling or crown | Keep the crown if you still have it and avoid chewing on that side. Do not use household glue. | Call within 24 hours |
| Swelling, fever or a bad taste | These can be signs of infection. Call us the same day; swelling that affects breathing or swallowing is a medical emergency — call 911. | Same day; 911 if breathing is affected |
| Broken braces or appliance | Cover any sharp end with orthodontic wax, keep loose pieces, and bring them to your appointment. | Call the same day for advice |
Severe tooth pain, swelling or a dental injury needs prompt assessment. Call the clinic rather than waiting for a routine check-up. Tell us if pain is affecting sleep or eating, and whether you have fever or swelling. Dental emergencies and medical emergencies require different care; RCDSO guidance explains this distinction.
Our emergency dental clinic provides urgent dental care, including:
Visit Mackenzie Smiles Dentistry at 250 Harding Blvd W, Suite 103, Richmond Hill, ON L4C 9M7, near Major Mackenzie Drive. Call before travelling so the team can review your concern and appointment availability. New patients are welcome.
Published hours are Monday–Friday, 9 a.m.–7 p.m., and Saturday, 9 a.m.–5 p.m. Mackenzie Smiles holds same-day emergency appointment slots on the days the clinic is open — call to confirm a time. We do not advertise 24-hour emergency care. If the clinic is closed and your concern cannot wait, seek another available dental provider. Use emergency medical services for potentially life-threatening symptoms.
Our general dentists review your symptoms, relevant health history, medications and allergies. An examination and dental X-rays, when appropriate, help identify the cause. The dentist will explain suitable options, their limitations and whether treatment, follow-up or referral is needed. A temporary measure may be followed by another visit; immediate permanent treatment cannot be guaranteed.
Depending on the assessment, care may include a dental filling, root canal therapy, tooth extraction or repair of a restoration.
Eligible CDCP patients are welcome. Emergency examinations, X-rays and certain related treatments may be covered under program rules. Not every service is covered; program limits, preauthorization and patient contributions may apply. Bring your plan information and ask the team to review proposed care before treatment.
Read our CDCP information and the official CDCP covered services.
Routine reviews, oral hygiene and a suitable sports mouthguard can help reduce preventable problems. Avoid using teeth to open packaging. Ask your dentist which preventive steps suit your circumstances; accidents can still happen despite good daily care.
For further patient education, read the CDA explanation of root canal treatment. This emergency service page helps you decide how to contact the clinic; our guide to warning signs provides additional background. Find our address and visit details on the Richmond Hill clinic location page.
Severe or persistent tooth pain, swelling, a knocked-out permanent tooth or a significant dental injury can need urgent dental attention. Contact a dentist promptly and describe your symptoms so the urgency and appropriate care can be assessed.
Call the clinic if you have swelling, an injury or pain that affects sleep or eating. If bleeding from a mouth injury does not stop despite pressure with a clean cloth, seek hospital care immediately. Do not wait for an online appointment response when urgent help is needed.
Call the dentist and explain how long the pain has lasted, whether you have swelling and what medicines you take. Ask a dentist or pharmacist about pain relief suitable for your health conditions. Do not place pain tablets directly against the tooth or gums.
The dentist must first assess the break and the health of the tooth. A filling, crown or other treatment may be recommended. Some problems need a temporary measure followed by a later appointment; immediate permanent repair cannot be guaranteed.
A dentist assesses the source and extent of the infection. Definitive care may involve drainage, root canal treatment or extraction. Antibiotics may be prescribed when indicated, but they do not replace treatment of the dental source. Tell the clinic promptly about swelling or fever.
Contact the dentist or orthodontic provider and describe what has broken and whether it is causing pain or injury. Avoid trying to glue or alter the appliance yourself. The team can advise on an assessment, temporary steps and whether a repair or replacement is appropriate.
Dental pain, swelling, dental injuries, broken teeth, or other urgent dental concerns should be assessed by a dentist.
