Wisdom tooth pain is usually caused by a tooth that is trying to come through without enough space, by inflammation of the gum flap covering it (pericoronitis), or by decay in a tooth that is hard to clean. Rinsing, painkillers and careful cleaning can ease it for a while, but recurring or severe pain needs a dental examination and often an X-ray.
What are wisdom teeth, and why do they hurt so often?
Wisdom teeth are the third molars, the last teeth at the very back of each side of the jaw. Most people have four, some have fewer, and a few have none at all. They usually appear in the late teens or twenties, long after the other permanent teeth are in place.
By that time the jaw often has little room left. The tooth may come through only partly, grow at an angle or stay trapped in the bone. Each of these situations can cause pain, either constantly or in episodes that come and go over months or years.
The most common causes of wisdom tooth pain
1. Eruption pressure
When a wisdom tooth pushes through the gum, the area can feel sore, tight and tender, a little like teething in children. This discomfort often comes in waves and may settle on its own if the tooth has room to come through fully.
2. Pericoronitis: an infected gum flap
When a tooth is only partly through, a flap of gum often remains over part of it. Food and bacteria collect underneath, and the gum becomes red, swollen and painful. This is called pericoronitis and it is the classic cause of a “swollen wisdom tooth”. It can make biting painful, leave a bad taste and sometimes limit how wide you can open your mouth.
3. Decay in the wisdom tooth or the tooth in front
Wisdom teeth are hard to reach with a toothbrush. Decay can develop in the wisdom tooth itself or in the back of the second molar in front of it, especially when the wisdom tooth is tilted against it. Deep decay can reach the nerve and cause strong, throbbing pain.
4. Pressure from an impacted tooth
A tooth that is stuck in the bone (impacted) does not always hurt, but it can press on the neighbouring tooth, trap food or, less often, be linked to a cyst. Read more in our guide to the impacted wisdom tooth.
Symptoms that point to a wisdom tooth problem
- Pain at the very back of the upper or lower jaw, sometimes spreading to the ear, the temple or the throat
- Red, swollen gum behind the last molar
- Pain when chewing or when closing your teeth together
- A bad taste or bad breath that comes from the back of the mouth
- Difficulty opening the mouth fully
- A headache on the same side, which many patients notice during a flare-up
Fever, swelling of the cheek or under the jaw, or difficulty swallowing are signs that the infection is spreading. These need urgent care; our article on facial swelling caused by a tooth explains when to go to the emergency room.
What you can do at home to ease the pain
Home measures do not treat the cause, but they can make the first days more comfortable while you arrange an appointment.
- Rinse gently with warm salt water (about half a teaspoon of salt in a glass of warm water) several times a day, especially after eating.
- Keep the area clean. Brush carefully right to the back with a soft brush, even if the gum is sore. Leaving it alone usually makes the inflammation worse.
- Take an over-the-counter painkiller such as paracetamol or ibuprofen, following the dose on the package and only if it is safe for you. Ask a pharmacist if you take other medicines or have a medical condition.
- Apply a cold compress on the outside of the cheek for 10 to 15 minutes at a time.
- Choose soft food and chew on the other side.
Avoid putting aspirin or crushed tablets directly on the gum: this burns the tissue. Avoid heat on the cheek when there is swelling, and do not try to “drain” a swollen gum yourself.
Do you need antibiotics?
Antibiotics are sometimes prescribed when there is a spreading infection, fever or marked swelling. They can calm the episode, but they do not remove the reason it started: the gum flap and the trapped bacteria remain, so the problem often returns. Antibiotics should always be prescribed by a dentist or doctor after an examination. Our article on antibiotics for a tooth infection explains what they can and cannot do.
How a dentist treats wisdom tooth pain
The first step is an examination and usually an X-ray, often a panoramic image, to see the position of the tooth, its roots and its relationship to the nerve and the neighbouring teeth.
Depending on what is found, treatment may include:
- Cleaning under the gum flap and rinsing the area, which often brings quick relief in mild pericoronitis
- Treating decay in the wisdom tooth or in the tooth in front of it
- Removing the wisdom tooth when it keeps causing inflammation, cannot come through properly, is decayed beyond repair or is damaging the neighbouring tooth
- Waiting and monitoring when the tooth is healthy, well positioned and causes no repeated problems
Not every wisdom tooth needs to come out. The decision depends on symptoms, position and the risk of future problems. Our complete guide to wisdom tooth removal describes the procedure, and our page on what to do after an extraction covers recovery.
When should you see a dentist?
Book an appointment if the pain lasts more than a few days, keeps coming back, wakes you at night or makes eating difficult. Seek urgent care the same day if you have swelling of the face or neck, fever, difficulty swallowing or breathing, or if you cannot open your mouth.
Early treatment is usually simpler, more comfortable and less expensive than treatment after several infections.

Frequently asked questions
Can wisdom tooth pain cause a headache or earache?
Yes. The nerves of the jaw, ear and temple are closely connected, so pain from an inflamed lower wisdom tooth is often felt in the ear, the temple or the side of the head. Many patients first think they have an ear problem. If the pain is on one side, near the back of the jaw, and gets worse when chewing, a wisdom tooth is a likely cause and a dental examination is worthwhile.
How long does wisdom tooth pain last?
Discomfort from a tooth that is simply coming through often settles within a few days. Pericoronitis may calm down in a few days with cleaning and rinsing, but it tends to come back as long as the gum flap remains. Pain that lasts longer than a week, keeps returning or becomes stronger should be checked by a dentist rather than managed with painkillers alone.
Can I go to work or school with wisdom tooth pain?
Usually yes, if the pain is controlled with simple painkillers and you have no fever or facial swelling. Keep the area clean, rinse after meals and eat soft food. If you develop swelling, fever, difficulty swallowing or a limited mouth opening, stop waiting and seek urgent dental or medical care the same day.
Is it safe to have a wisdom tooth removed while it is inflamed?
It depends on how severe the inflammation is. In many cases the dentist first calms the infection with cleaning, rinses and sometimes medication, and removes the tooth a little later when the tissues are less inflamed and the mouth opens more easily. In other cases removal can be done straight away. The decision is made after an examination.
Does a wisdom tooth that hurts always have to be removed?
No. Pain from normal eruption can disappear once the tooth is fully through, and a single mild episode of pericoronitis can sometimes be managed with cleaning. Removal is usually advised when episodes keep returning, when the tooth cannot come through properly, when it is decayed beyond repair or when it is damaging the tooth in front of it.
Can I use clove oil for wisdom tooth pain?
Clove oil has a mild numbing effect and some people find short-term relief from a small amount on cotton held against the area. It does not treat the infection, and using too much can irritate the gum. Salt-water rinses, careful cleaning and an appropriate painkiller are more reliable, and an examination is still needed if the pain continues.
