Wisdom Tooth Pain — Gum Flap or Pressure
Pain at the back of the jaw is often a wisdom tooth, and swelling toward the throat should not wait.
What is happening?
Wisdom-tooth pain usually comes from a tooth that is short of room: pressure on the molar in front, an infected gum flap over a partly erupted tooth (pericoronitis), decay in a third molar you cannot clean, or a cyst around an impacted tooth.
Same-day care
Common symptoms
- Pain or pressure at the back of the jaw
- A swollen, tender gum flap over the tooth
- Pain when you open wide or chew
- A bad taste
- Pain radiating toward the ear
Is it urgent?
Swelling spreading toward the throat. Trouble opening your mouth. Trouble swallowing — same day.
While a wisdom tooth is flaring
Rinse the flap
Warm salt water, especially under the gum flap if you can reach it gently.
Soft food, other side
Chew away from the sore corner. Pain relief by mouth, as the label directs, and a cold compress on the outside of the jaw.
Call if it is spreading
Facial swelling, limited opening, or trouble swallowing makes this today, not the next cleaning.
Common causes
Impaction pressure against the neighbouring molar · Pericoronitis — an infected gum flap over a partly erupted tooth · Decay in a third molar that is hard to clean · A cyst around an impacted tooth
How we diagnose it
We look at the gum flap, how far the tooth has erupted, and whether opening is limited. An x-ray, and sometimes a focused 3D scan, shows the angle of the tooth and the nerve. Removal is a recommendation after that image, not a default.
How we treat it
Calm the flare first
A swollen flap may need cleaning, rinses, and sometimes antibiotics before anyone talks about surgery.
Plan removal if it will keep returning
Surgical removal is scheduled with the sedation level you actually need. Same-day emergency removal is for infection and pain, not for a convenient four-tooth plan invented over the phone.
Sedation for this kind of treatment
The painful visit itself is managed with local anesthetic, and nitrous may be available. Taking a wisdom tooth out under IV sedation or general anesthesia is a booked procedure: fasting, an escort, and a provider on the schedule.

(416) 483-0000Is wisdom tooth pain always an extraction today?
No. Many flares are an infected gum flap that we clean and settle first. Removal is planned from an x-ray and your symptoms, often within a day or two if the infection is the reason.
I can barely open. Is that urgent?
Yes. Limited opening, swelling toward the throat, or trouble swallowing should be the same day.
Can I be asleep for the removal?
If we hold the authorization for that level, it is scheduled — not added when you walk in unfasted. Tell us when you book the surgical visit.
