Emergency Dentist Ottawa: Where to Go and What's Covered

A toothache at 8 p.m. on a Sunday does not have to end in a hospital waiting room, but a swollen face that makes swallowing hard should.

If you need an emergency dentist in Ottawa, start with the Ottawa Dental Society's on-call line at 613-523-4185. It runs from 9 a.m. to 9 p.m., seven days a week, and it points you to the dentist on duty that day. Go to a hospital emergency department instead when the problem has moved beyond the tooth: trouble breathing or swallowing, or fever with facial swelling. Public programs, including the Canadian Dental Care Plan (CDCP) and the Ontario Seniors Dental Care Program, can cover part of the bill for people who qualify.

Key Highlights

TL;DR: Call your own dentist first, because Ontario dentists must tell patients how to reach emergency care. If you have no dentist, or yours cannot be reached, call the Ottawa Dental Society line between 9 a.m. and 9 p.m. Use a hospital emergency department for breathing or swallowing trouble, fever with swelling, or bleeding that will not stop.

What Counts as a Dental Emergency in Ottawa

The Ottawa Dental Society (ODS) runs its emergency service for four things only: pain relief, a tooth abscess, facial swelling, and a knocked-out tooth. The society says the service is for "emergency symptoms only", so a lost filling that does not hurt is better handled by your regular dentist during office hours.

The Royal College of Dental Surgeons of Ontario (RCDSO), the regulator, offers a slightly wider list of "true emergencies": trauma, significant infection, prolonged bleeding, or pain that over-the-counter medication cannot manage. The Ontario Dental Association (ODA) adds that a loose adult tooth is a serious problem and a chipped or broken tooth can often be saved if you act quickly.

Pain alone can be hard to read. A tooth abscess is a pocket of pus caused by a bacterial infection, and Mayo Clinic notes that if it bursts, the pain may ease and make you think the problem is gone. You still need treatment, because an abscess will not clear up without it.

What to Do Until You Reach an Emergency Dentist

The ODA gives practical steps for the wait. For a toothache, call a dentist right away and ask about pain medication. Do not put a heating pad or hot water bottle on your jaw, because heat makes things worse. Do not place a pill on the sore tooth either. For a chipped or broken tooth, rinse your mouth with water, use a cold compress for swelling, and keep any fragment in cold milk.

A knocked-out adult tooth is the one case where minutes matter. The ODA says to rinse it gently in cool water without scrubbing or soap, and to place it back in the socket if you can, holding it with clean gauze or a washcloth. If that is not possible, or it might be swallowed, store it in cold milk. A tooth put back within 10 minutes has a fair chance of taking root again, and after an hour the chances are poor. Go to a dentist right away.

A knocked-out baby tooth is different. The ODA says baby teeth are never replanted, so keep the child calm, rinse the mouth, and use gauze if there is bleeding. Ottawa Public Health gives the same warning and adds that any sign of a head injury, such as unconsciousness, nausea or headache, means calling 911.

For a bitten lip or tongue that is bleeding, press a clean cloth on it. If the bleeding does not stop, the ODA says to go to the hospital right away. If something is stuck between your teeth, try floss gently and never a pin or sharp object.

Emergency Dentist in Ottawa After Hours, on Weekends and on Holidays

Your own dentist is the best first call, even in the evening. Under Ontario's professional misconduct regulations, a dentist who fails to arrange emergency services for their patients, or to tell them how to get them, can face a professional misconduct finding. The RCDSO says that during office hours, an emergency patient should be seen the same day or the next day at the latest. When the office is closed, the message on the line should tell you where to go.

If you have no dentist, or yours cannot be reached, use the ODS Dental Emergency Service. The process is simple and slightly unusual. Call 613-523-4185 and listen to the recording for the name and number of the dentist on duty. Do not leave a message. Hang up and phone the dentist named to book an appointment. On-call dentists take emergency cases from 9 a.m. to 9 p.m., seven days a week.

Seven days a week covers weekends. The ODS page lists no exceptions for statutory holidays, so on a holiday call the same number and listen to the recording. If it does not give you a dentist, treat that as a reason to try Health811 or the hospital rather than waiting.

Before the dentist's office will see you, expect a short list of requests from the ODS: proof of identification with your name and address, any dental insurance or government program details, a method of payment such as cash or credit card, and your medical history, including current medications and allergies.

Outside 9 a.m. to 9 p.m., the ODS lists no on-call dentists. Health811 is a nurse line you reach by dialling 8-1-1, 24 hours a day, according to CHEO, and a nurse can help you decide how urgent the problem is. For red-flag symptoms, skip the phone and go to hospital.

Medical walk-in clinics treat medical problems, not teeth. Our walk-in clinics guide explains where they fit if you also need a doctor, and the Ottawa healthcare resources guide collects other services. If you want to find a regular dentist before an emergency happens, browse the 406 dentist listings in our directory or check a dentist's registration on the RCDSO Find a Dentist register.

When a Hospital Emergency Department Is the Right Place

Go to a hospital when the infection or injury is bigger than the tooth. Mayo Clinic advises going to an emergency room if you have a fever and facial swelling and cannot reach your dentist, or if you have trouble breathing or swallowing. Those signs can mean the infection has spread deeper into the jaw, throat or neck. If breathing is severely affected, call 911.

The Ottawa Hospital's emergency departments at the Civic and General campuses are open 24 hours a day, seven days a week. There is no emergency department at the Riverside Campus. Bring your health card, a list of your medications, and any health records you have. A triage nurse sees everyone first and the sickest patients are treated first, so a stable toothache will wait behind more serious cases.

Expect the hospital team to deal with the medical side and send you back to a dentist for the tooth. CHEO's own page describes the process for children: after hours, a dental emergency is assessed in the emergency department by a physician, who decides whether a dentist needs to be called. Mayo Clinic notes that it is dentists who drain an abscess, treat it with a root canal, or pull the tooth.

For a visit to hospital, OHIP covers doctor and nursing services and tests such as blood work and x-rays. It does not cover dental services provided in a dentist's office. It does cover some dental surgery in hospital, such as fracture repair, tumour removal and reconstructive surgery, and medically necessary tooth removal with prior approval.

What an Emergency Dentist Visit Costs in Ottawa

No official price list exists for emergency dental visits in Ottawa, and any figure you find online is one clinic's own estimate. The ODS is plain about it: there will be a fee for services provided, and patients are responsible for the diagnosis and treatment they receive. Treatment can include an exam, x-rays and then the procedure itself, so the bill depends on what the dentist finds.

Ontario dentists set their own fees. The ODA says the annual Suggested Fee Guide is only a reference, dentists are not required to follow it, and fees may land above or below it. The guide is not published on the ODA website either, so you cannot look up a fair price in advance. Ask for an itemized estimate by phone or in the chair before you agree to treatment.

Two protections are worth knowing. The RCDSO says it is not appropriate to require a deposit as a condition of emergency care. It also says a patient's inability to pay should not be a barrier to appropriate palliative treatment of true emergencies. On-call dentists should offer the same payment terms as the patient's regular dentist, such as accepting payment from specific social services plans.

If you have private dental coverage, bring the details. If you are enrolled in a public program, bring that card. The next two sections explain what those programs pay.

CDCP and the Ontario Seniors Dental Care Program: What They Cover

The Canadian Dental Care Plan covers a share of many urgent services. According to Canada.ca, the list includes emergency exams, x-rays, pain control for diseased teeth, root canal treatments, procedures to reduce infection and relieve pain, treating abscesses, removal of teeth and roots, and surgical incisions, including draining. Some services require preauthorization, and orthodontic services are not available.

To apply, you must meet all four requirements: no access to private dental insurance or coverage, you and your spouse or partner filed tax returns in Canada, your adjusted family net income is under $90,000, and you are a Canadian resident for tax purposes. Applications for the 2026-2027 benefit period are open. If you had coverage in 2025-2026 and did not renew, you can re-apply, but you will have a gap in coverage.

How much the plan pays depends on income. Below $70,000 the CDCP covers 100 per cent of its established fees. Between $70,000 and $79,999 it covers 60 per cent, and between $80,000 and $89,999 it covers 40 per cent. Your dentist's fee may be higher than the CDCP's established fee, and you pay the difference. In the plan's own example, a provider charges $145 for a service with an established fee of $134, and the patient pays the remaining $11. The plan pays providers directly, so you should not have to pay the full cost upfront, but you must go to a participating dentist. Ottawa Public Health points people to Sun Life's CDCP provider search or 1-888-888-8110 to find one, and the plan's own line is 1-833-537-4342. There is no fee to apply, so be careful of scams.

The Ontario Seniors Dental Care Program (OSDCP) offers free routine dental care to low-income seniors 65 or older, and its covered services include repairing broken teeth, removing teeth, and treating infection and pain. You qualify with an annual net income of $25,480 or less as a single senior, or $42,290 or less as a couple, and no other dental benefits apart from the CDCP. You can hold both programs. Dentures are only partly covered.

The catch for emergencies is where the OSDCP is delivered: through public health units and partner Community Health Centres, not through private dental offices. It is therefore not an after-hours option. The Ottawa Dental Society says OSDCP clients should call the Dental Information Line at 613-580-3300 and choose option 3. The program's own line is 1-833-207-4435. Coverage ends on July 31 each year no matter when you enrol. For other money-saving options for older residents, see our senior discounts guide.

Emergency Dental Care for Children and Low-Income Adults

Healthy Smiles Ontario (HSO) covers urgent and emergency dental care for children and youth 17 and under, including treatment of a child's toothache. For emergency or essential care, you must show a clinical need and financial hardship. Coverage lasts six months from enrolment, and each child can use that stream a maximum of three times in their lifetime. Call your dentist's office or your public health unit to see who participates. If you have no dentist, Ottawa Public Health says to check the Ottawa Dental Society's list of participating dentists (613-523-3876) or call its own Dental Information Line at 613-580-3300.

CHEO's Emergency Department treats ages 0 to 18 and is open 24 hours a day. CHEO's page says its dental clinic handles emergencies during regular working hours of 8:45 a.m. to 4:30 p.m., and after hours a child is assessed in the emergency department first. CHEO also notes that work is affecting access to its main entrance until October 30, 2026, so plan your arrival.

Adults on low incomes have a few routes. Ottawa Public Health runs four dental clinics, at 255 Centrum Boulevard in the east, 1580 Merivale Road in the west, 2525 St. Laurent Boulevard in the south and 40 Cobourg Street downtown. They are by appointment only, and the Dental Information Line is the way in. They serve people enrolled in programs such as Healthy Smiles Ontario, the OSDCP, Ontario Works, the Essential Health and Social Supports program and the CDCP. CDCP clients must call first to confirm eligibility.

Ontario Works recipients can get urgent dental care through the same line. Limited emergency dental care may be available for low-income adults and older adults who qualify for Essential Health and Social Supports (EHSS); call 3-1-1 or 613-580-2400. If you have just moved here and are still setting up health coverage, our newcomer settlement guide covers the first steps.

FAQ

Q: Is there a 24-hour emergency dentist in Ottawa?

The Ottawa Dental Society's on-call line, 613-523-4185, is listed as 9 a.m. to 9 p.m., seven days a week, so it is not a round-the-clock service. Outside those hours, call Health811 at 8-1-1 for nurse advice. Go to a hospital emergency department if you have trouble breathing or swallowing, fever with facial swelling, or bleeding that will not stop.

Q: Can I go to the emergency room for a toothache?

Yes, if you have red flags such as fever with facial swelling or trouble swallowing. For pain alone, expect an assessment and a referral. CHEO's page says an emergency physician decides whether a dentist needs to be called, and Mayo Clinic notes dentists are the ones who drain abscesses, perform root canals and pull teeth.

Q: Does OHIP cover emergency dental care?

OHIP covers a hospital emergency visit, including doctor and nursing services and tests such as x-rays. It does not cover dental services provided in a dentist's office. It covers some in-hospital dental surgery, including fracture repair and medically necessary tooth removal with prior approval, so the dentist's bill is usually yours unless a dental program pays it.

Q: Will the Canadian Dental Care Plan pay for an emergency visit?

If you are enrolled, the plan covers emergency exams, x-rays, pain control, root canals and tooth removal, at its established fees. Your share depends on income, and your dentist may charge more than the plan pays. Ask whether the dentist participates before you book, and bring your CDCP card to the appointment.

Q: Can seniors use the Ontario Seniors Dental Care Program after hours?

Not easily. The program delivers care through public health units and partner Community Health Centres, not private offices. Ottawa seniors should call the Dental Information Line at 613-580-3300 and choose option 3. For a true emergency at night, such as facial swelling or breathing trouble, use a hospital emergency department.

Q: What should I do if an adult tooth is knocked out?

Handle it gently, rinse it in cool water without scrubbing, and try to place it back in the socket, holding it with gauze. If you cannot, keep it in cold milk. The ODA says a tooth reinserted within 10 minutes has a fair chance of taking root again. Call a dentist right away.

Final Thoughts

Most dental emergencies in Ottawa come down to one phone call. Try your own dentist, because Ontario dentists must arrange emergency care for their patients. If that fails, the Ottawa Dental Society line connects you with the dentist on duty from 9 a.m. to 9 p.m., every day. Keep the hospital for the symptoms that mean the problem has left the tooth.

Money should not keep you from calling. Dentists set their own fees, so ask for an itemized estimate, and check now whether you qualify for the CDCP, the seniors program or Healthy Smiles Ontario. Save 613-523-4185 in your phone today. If you are still looking for a regular dentist, start with our Ottawa dentist directory.
