Patient Safety and After-Hours Dental Emergencies
Have a dental problem when Riverfront Dental is closed? Here is what to do. For trouble breathing or swallowing, swelling spreading toward your eye or neck, or a serious injury to your face or jaw, call 911 or go to the nearest emergency department. Cambridge Memorial Hospital is across Coronation Boulevard from our clinic.
What should I do if the clinic is closed?
When Riverfront Dental is closed, leave a voicemail at (519) 621-2111 or email admin@riverfrontdental.ca. Describe what happened and your symptoms, and include a phone number where we can reach you. Messages may not be read until the office reopens. Do not wait for a reply if your symptoms are severe or getting worse. Go to an emergency department instead.
Our regular hours are:
- Monday to Wednesday: 9 a.m. to 5 p.m.
- Thursday: 11 a.m. to 7 p.m.
- Friday: 9 a.m. to 4 p.m.
- Saturday: 9 a.m. to 3 p.m., two Saturdays each month
- Sunday: closed
When should I go to the hospital instead?
Go to an emergency department or call 911 when a dental problem affects your breathing or your general health. A dental office is not set up for a spreading infection that affects breathing. It is not set up for a serious facial injury either. Most toothaches and broken teeth can wait for a dental visit. The signs below cannot.
Go to hospital right away if you have:
- Swelling in your face or neck that is spreading, or swelling near your eye
- Trouble breathing or swallowing
- Bleeding that will not stop with firm pressure
- An injury to your jaw, face or head
- A high fever along with dental swelling
Health advice overnight: call 811
Health811 is Ontario's free health advice line. Call 811 any time, day or night, to speak with a registered nurse. The nurse can help you decide whether a dental problem needs the emergency department or can wait for a dental appointment. Health811 is for non-urgent concerns and does not replace 911 in an emergency.
What can wait until the clinic opens?
Some dental problems are uncomfortable but not urgent. You can usually call us when we open if you have:
- A small chip with no pain
- A lost filling or crown with little discomfort
- Mild sensitivity to hot or cold that fades quickly
- Food stuck between teeth (try flossing gently first)
A knocked-out adult tooth is different. It is time-sensitive, so follow the first-aid steps on our emergency dental page and get care as soon as you can.
How we keep you safe during treatment
Your dentist at Riverfront Dental reviews your health history, medicines and allergies before treating you. Tell us about any changes at every visit. That includes new medicines, pregnancy or recent surgery. These details can change which freezing, medicine or X-ray is safe for you. If something feels wrong during treatment, tell us and we will stop.
X-ray and CBCT safety
Dental X-rays use a low dose of radiation. Your dentist chooses which images you need based on your exam and history. Tell us if you are or might be pregnant.
Infection control
Our team sterilizes reusable instruments and disinfects treatment rooms between patients. Read how on our infection prevention and control page.
Sedation
Nitrous oxide is the sedation option at Riverfront Dental. It wears off within minutes after the mask comes off. Riverfront Dental does not offer IV sedation.
How can I raise a concern about my care?
If you have a concern about the safety of your care, talk to your dentist or call the clinic at (519) 621-2111. You can also contact the Royal College of Dental Surgeons of Ontario, which regulates dentists in Ontario and handles complaints from the public. All three dentists at Riverfront Dental are general dentists.
