Wisdom Tooth Pain: Why It Happens and When Removal Makes Sense
Why wisdom teeth hurt, safe ways to ease the pain before your appointment, when removal is recommended, and the warning signs that need urgent care.
Wisdom teeth are the last molars to arrive, usually between the late teens and mid-twenties. For some people they come in quietly; for many they cause pressure, sore gums or repeated flare-ups. Here is what is going on and what you can do about it.
Why wisdom teeth hurt
As a wisdom tooth pushes through the gum, the tissue over it can become inflamed — especially when the tooth is coming in at an angle or there is not enough room for it. A partially erupted wisdom tooth is hard to clean, so food and bacteria collect around it and the gum beside it swells.
Pain can also come from the tooth pressing against the neighbouring molar, or from decay starting in a wisdom tooth that is difficult to brush.
Easing the pain before your appointment
These steps may settle symptoms temporarily, but they do not fix the underlying cause. Book an assessment so the tooth can be examined and X-rayed.
- Rinse gently with warm salt water several times a day
- Brush carefully around the area to keep food from lodging there
- Use an over-the-counter pain reliever as directed on the package
- Apply a cold pack to the outside of your cheek for swelling
- Avoid very hot, hard or crunchy foods on that side
When removal is recommended
Not every wisdom tooth needs to come out. Removal is usually advised when a tooth is impacted, repeatedly infected, damaging the neighbouring tooth, causing crowding problems, or too decayed or difficult to clean to save. Your dentist will show you the X-ray and explain the options before anything is scheduled.
Recovery
Most people take a few days of easier routines after an extraction: soft foods, gentle rinsing after 24 hours, no straws or smoking, and no strenuous exercise for the first couple of days. Some swelling is normal and peaks around the second day.
When it becomes urgent
Difficulty swallowing or breathing, rapidly spreading swelling of the face or neck, fever with facial swelling, or uncontrolled bleeding are not waiting-room problems — seek emergency medical care immediately, or call 911.
Common questions
How do I stop wisdom tooth pain at night?
Warm salt-water rinses, an over-the-counter pain reliever taken as directed, and sleeping with your head slightly elevated can take the edge off until you are seen. Persistent night pain usually means the tooth needs an assessment soon.
Do all wisdom teeth need to be removed?
No. Wisdom teeth that have come in fully, are healthy, cleanable and bite correctly can stay. Removal is recommended when a tooth causes repeated problems or threatens neighbouring teeth.
How long does recovery from wisdom tooth removal take?
Most people feel noticeably better within three to five days, with the area continuing to heal over a couple of weeks. Lower wisdom teeth, which are often more involved, can take a little longer.
What does an impacted wisdom tooth mean?
It means the tooth has not fully emerged because it is blocked by bone, gum or the angle of its growth. Impacted teeth can stay quiet for years or cause repeated flare-ups, which is why they are assessed with an X-ray.
