Wisdom Tooth Pain: Why It Happens and How to Get Relief
Dr Tristan Tinn

Key Takeaways
- •Wisdom teeth cause pain because there is often not enough room for them. The most common causes are impaction, pericoronitis (gum flap infection), and decay.
- •Home remedies like ibuprofen, salt water rinses, and clove oil can provide temporary relief, but they are not a long-term fix.
- •Not all wisdom teeth need removal. NICE guidelines advise against extracting wisdom teeth that are not causing problems.
- •NHS extraction costs £75.50 (Band 2). Private extraction ranges from £100 to £500+ per tooth depending on complexity.
- •Most people recover within one to two weeks. Avoid smoking, straws, and vigorous rinsing to prevent dry socket.
Wisdom teeth are the third molars at the very back of your mouth. They typically try to come through between the ages of 17 and 25, though they can cause trouble at any age.
For many people, there simply is not enough room. This leads to pain, swelling, and sometimes infection. Here is what is going on and how to find relief.
Why Do Wisdom Teeth Cause Pain?
There are several reasons wisdom teeth can become painful. Understanding the cause helps determine the right treatment.
Impaction
When there is not enough space in the jaw for a wisdom tooth to fully emerge, it may become impacted. This means it is stuck against the neighbouring tooth, trapped within the jawbone, or angled in the wrong direction.
Impacted wisdom teeth can cause a deep, aching pain in the back of the jaw that may radiate to the ear or temple. They can also put pressure on adjacent teeth, potentially causing damage or crowding.
Pericoronitis (Gum Flap Infection)
This is one of the most common causes of wisdom tooth pain. When a wisdom tooth only partially breaks through the gum, a flap of gum tissue (called an operculum) can remain over part of the tooth.
Food and bacteria easily become trapped under this flap, causing infection and inflammation. Symptoms include pain, swelling, a bad taste, and sometimes difficulty opening the mouth fully. Pericoronitis can recur repeatedly until the wisdom tooth fully erupts or is removed.
Decay
Wisdom teeth are notoriously difficult to clean because of their position at the very back of the mouth. This makes them particularly vulnerable to decay.
Because they are hard to access, decay may go unnoticed until it becomes extensive enough to cause pain. A decayed wisdom tooth can cause persistent toothache and may eventually lead to a dental abscess.
Cyst Formation
In uncommon cases, a fluid-filled cyst can develop around an unerupted or impacted wisdom tooth. These are usually painless initially but can grow over time and damage surrounding bone and teeth. Cysts are typically discovered on routine X-rays.

Symptoms of Wisdom Tooth Problems
Not sure if your pain is coming from a wisdom tooth? Here are the common signs to watch for.
- Pain or tenderness at the back of the jaw, behind the last visible tooth
- Swollen, red, or tender gums at the back of the mouth
- A bad taste or unpleasant smell from the back of the mouth
- Difficulty opening the mouth fully (trismus)
- Pain that radiates to the ear, temple, or side of the face
- Swelling of the cheek or jaw
- Headaches or earaches with no other obvious cause
- Difficulty chewing or biting on that side
Home Remedies for Wisdom Tooth Pain
These measures can help manage discomfort while you wait to see a dentist. They provide temporary relief but are not a substitute for professional treatment.
- Salt water rinses: Dissolve half a teaspoon of salt in a glass of warm water and rinse gently around the affected area several times a day. This can help reduce inflammation and flush out trapped debris.
- Ibuprofen: Usually the most effective over-the-counter painkiller for wisdom tooth pain as it reduces both pain and inflammation. Take 400mg up to three times daily with food, or alternate with paracetamol for maximum relief.
- Cold compress: Apply an ice pack wrapped in a towel to the outside of your cheek for 15 to 20 minutes to help reduce swelling.
- Clove oil: A small amount of clove oil on a cotton ball, applied to the affected area, may provide temporary numbing relief. The active ingredient (eugenol) has natural anaesthetic properties.
- Thorough but gentle cleaning: Use a small-headed toothbrush to carefully clean around and behind the wisdom tooth, including under any gum flap. An interdental brush or water flosser can help reach difficult areas.
- Corsodyl (chlorhexidine) mouthwash: Can help control bacteria around a partially erupted wisdom tooth. Use for no more than two weeks as it can stain teeth with prolonged use.
When to see a dentist urgently: Home remedies are a stopgap, not a cure. See a dentist if pain lasts more than a few days, keeps returning, or you develop swelling, difficulty opening your mouth, a fever, or a bad taste that will not go away. For severe symptoms, see our dental emergency guide.
When Does a Wisdom Tooth Need to Be Removed?
Not all wisdom teeth need to come out. Your dentist may recommend extraction if:
- You have had recurrent episodes of pericoronitis
- The tooth is impacted and causing pain or damaging the adjacent tooth
- There is decay that cannot be easily treated due to the tooth's position
- An abscess or cyst has developed
- The tooth needs to be removed as part of orthodontic treatment planning
NICE guidelines advise against removing wisdom teeth that are not causing problems (prophylactic extraction), even if they are impacted. If your wisdom teeth are not causing symptoms, they are generally best left alone with regular monitoring.

What Does Wisdom Tooth Extraction Involve?
Wisdom tooth extraction is one of the most commonly performed dental procedures in the UK. Here is what to expect depending on the complexity.
| Type | When It's Used | What's Involved | Anaesthetic |
|---|---|---|---|
| Simple extraction | Fully erupted, accessible tooth | Tooth loosened and removed. Socket heals naturally. | Local anaesthetic |
| Surgical extraction | Impacted, partially erupted, or curved roots | Small gum incision, may need bone removal. | Local, sedation, or general |
| Hospital referral | Deeply impacted, near the nerve | Specialist oral surgery team. | Usually general anaesthetic |
If you are nervous about the procedure, ask about sedation options. Many practices and hospitals offer this for wisdom tooth removal. You should not feel pain during the procedure, only pressure and pushing. Most people describe it as less painful than they expected.
Cost of Wisdom Tooth Removal in the UK
The cost depends on whether you are treated on the NHS or privately, and the complexity of the extraction.
| Treatment | NHS Cost | Private Cost |
|---|---|---|
| Simple extraction | £75.50 (Band 2) | £100 to £300 per tooth |
| Surgical extraction | £75.50 (Band 2) | £200 to £500+ per tooth |
| Sedation (if required) | Included if clinically needed | £200 to £400 additional |
| X-rays | Included in Band 2 | £20 to £100 |
The NHS Band 2 charge applies whether one or multiple wisdom teeth are removed in the same course of treatment. If you are struggling to find an NHS dentist, see our guide on the NHS dentist crisis and how to find available appointments. Many private dentists also offer payment plans to spread the cost.
Recovery After Wisdom Tooth Extraction
Most people recover well within one to two weeks. Here is a typical timeline.
| Timeframe | What to Expect | Tips |
|---|---|---|
| First 24 hours | Some bleeding, swelling, and discomfort | Rest. Avoid hot drinks. Do not rinse or spit vigorously. |
| Days 2 to 3 | Swelling peaks around day 2 | Continue painkillers. Begin gentle salt water rinses. |
| Days 4 to 7 | Pain and swelling gradually improving | Return to normal eating gradually. Avoid extraction site. |
| Weeks 1 to 2 | Most discomfort resolved. Stitches dissolving. | Dissolvable stitches fall out in 7 to 10 days. |
What to Eat After Wisdom Tooth Removal
Stick to soft, cool foods for the first few days. Good options include yoghurt, lukewarm soup, mashed potato, scrambled eggs, smoothies, and ice cream. Avoid hot foods and drinks for the first 24 hours, as heat can increase bleeding. Gradually return to normal foods as comfort allows, but avoid chewing directly on the extraction site for at least a week.
Watch out for dry socket: If pain suddenly worsens 2 to 4 days after extraction, you may have developed dry socket (alveolar osteitis). This happens when the blood clot is lost from the socket, exposing the underlying bone. It is more common with lower wisdom teeth. Avoid smoking, drinking through straws, and vigorous rinsing in the first few days to reduce your risk. Your dentist can treat dry socket with a medicated dressing. See our full guide on dry socket for more.
Bottom line: Wisdom tooth pain is very common and usually very treatable. Whether it is managed with good cleaning and monitoring or requires extraction, your dentist can help you find the right approach for your situation.
Frequently Asked Questions
How long does wisdom tooth pain last?
It depends on the cause. Eruption pain may come and go over several weeks. Pericoronitis may settle within a week or two but often recurs. Pain from decay or an abscess will not resolve without dental treatment. See a dentist if pain lasts more than a few days, keeps returning, or is accompanied by swelling.
Can I manage wisdom tooth pain at home?
You can manage mild pain temporarily with ibuprofen, salt water rinses, and clove oil. But home remedies are a stopgap. If pain persists, keeps returning, or you develop swelling or difficulty opening your mouth, see a dentist.
How much does wisdom tooth removal cost on the NHS?
NHS wisdom tooth extraction costs £75.50 (Band 2) in 2026, covering the extraction and any X-rays. Private extraction costs £100 to £300 for simple removal and £200 to £500+ for surgical extraction, plus £200 to £400 for sedation if needed.
Do all wisdom teeth need to be removed?
No. NICE guidelines advise against removing wisdom teeth that are not causing problems. If yours are symptom-free, they are best left alone with regular monitoring. Removal is only recommended for recurrent infections, decay, damage to adjacent teeth, or other specific clinical reasons.
What is dry socket and how do I avoid it?
Dry socket occurs when the blood clot is lost from the extraction site, exposing bone. It causes sudden worsening pain 2 to 4 days after extraction. Avoid smoking, straws, spitting, and vigorous rinsing to reduce your risk. See our dry socket guide for more detail.
How long is recovery after wisdom tooth removal?
Most people recover within one to two weeks. Swelling peaks around day two and gradually improves. You can usually return to work after 2 to 3 days for simple extractions. See our tooth extraction recovery guide for a full timeline.
Can a wisdom tooth cause ear pain or headaches?
Yes. Impacted or infected wisdom teeth can cause referred pain to the ear, temple, or along the jaw. The nerves serving wisdom teeth connect closely to those supplying the ear and side of the head. If you have persistent ear pain or headaches with no other cause, have your wisdom teeth checked.
Is wisdom tooth removal painful?
During the procedure you should not feel pain as the area is numbed with local anaesthetic. You may feel pressure and pushing but no sharp pain. Sedation options are available if you are anxious. After the procedure, some discomfort is normal for a few days but is managed with painkillers.
What should I eat after wisdom tooth removal?
Stick to soft, cool foods for the first few days: yoghurt, lukewarm soup, mashed potato, scrambled eggs, smoothies, and ice cream. Avoid hot foods for 24 hours. Return to normal foods gradually. Stay hydrated but avoid straws.
