01In brief
Swollen cheek and toothache: what should I do?
Urgent: get it seen today
A swollen cheek with a toothache most often signals an infection coming from a tooth (an abscess). It needs to be seen quickly, ideally the same day. In Valleyfield, the Go Dentiste clinic sees emergencies 7 days a week: call 514-533-3368 to get an arrival time, subject to availability. If the swelling spreads to your eye or neck, or if you have trouble swallowing or breathing, go straight to the hospital emergency room or call 911.

02What to do now
What to do while you wait to be seen
These steps bring relief, but they do not treat the infection: only treating the tooth deals with the cause.
- Call the clinicAt 514-533-3368, from 8 a.m. Monday to Thursday and from 9 a.m. Friday to Sunday. Mention the swelling: it is seen as a priority.
- Cold, never heatA cold compress wrapped in a cloth on your cheek, 15 minutes at a time. Heat can make swelling worse.
- Keep your head raisedSleep with an extra pillow: pressure and swelling often go down when your head is raised.
- Ask your pharmacistFor a pain reliever suited to your health and your medications. An antibiotic, if needed, does not replace treating the tooth.
What to avoid
- Piercing or squeezing the swelling yourself
- Putting heat on your cheek
- Putting aspirin directly on the gum
- Taking an old antibiotic you found at home
- Waiting for the swelling to “go away” on its own
Warning signs: Call 911 or go to the hospital emergency room (Hôpital du Suroît, in Valleyfield) if swelling spreads to the eye, under the jaw or to the neck, if you have trouble breathing, swallowing or opening your mouth, or if you have a high fever.

Hospital, clinic or appointment: how to decide

04At the Valleyfield clinic
How a swollen cheek is relieved at the clinic
The dentist examines the tooth and gum, then takes a digital X-ray to locate the infection. The dentist then relieves the pressure: draining the abscess, opening the tooth and starting a root canal, or extracting the tooth when it cannot be kept.
The options and their costs are explained to you before any treatment. An antibiotic may be prescribed if the infection is spreading, in addition to treating the cause. A follow-up is planned to finish the treatment.

06FAQ
Frequently asked questions: swollen cheek in Valleyfield
Can a swollen cheek wait until tomorrow?
If you are breathing and swallowing normally, with no high fever, call the clinic as soon as it opens: the swelling needs to be seen quickly, ideally the same day (subject to availability). If it is getting worse fast, spreading to your eye or neck, or making it hard to breathe, do not wait: go to the hospital emergency room.
Is an antibiotic enough to fix the problem?
No. An antibiotic can calm the infection, but its source is in the tooth or the gum. Without treating the tooth, the infection usually comes back. The dentist determines the right treatment after the exam.
Ice or heat on my cheek?
Cold. A cold compress wrapped in a cloth, 15 minutes at a time. Avoid heat, which can make swelling worse.
Why is the swelling worse in the morning?
When you lie down, more fluid builds up in your face. Sleeping with your head raised helps. Swelling that gets bigger day after day needs to be seen quickly.
Do you see new patients for a swollen cheek?
Yes. New patients are seen for emergencies in Valleyfield, no referral needed. Bring ID, your insurance card or your Canadian Dental Care Plan (CDCP) number, and a list of your medications.
