Can wisdom teeth cause jaw pain?

The ache sits at the back of your jaw and your mouth will not open as far as usual. A wisdom tooth is the obvious suspect, and many people reading this are either waiting to find out or still recovering from having one taken out.

Below I explain how wisdom teeth cause jaw pain, what is normal after removal and how your jaw muscles can mimic a tooth problem. You will also find a self-check from my physiotherapy practice and a guide to when this cannot wait.

Key takeaways

Yes, wisdom teeth can cause jaw pain. The NHS lists pain, swelling, gum infection and abscesses among the problems they cause when there is no room for them to come through (NHS Wisdom tooth removal, 2024). A Scottish dental guideline points out that TMD causes the same pain and limited opening, so a wisdom tooth with no signs of infection may not be the culprit (SDCEP, 2026).

• Infection around a partly erupted wisdom tooth usually brings swollen gum, a bad taste and sometimes fever (SDCEP, 2026).
• A sore, stiff jaw after removal is common and usually settles within 2 weeks (NHS Wisdom tooth removal, 2024).
• Trouble breathing or swallowing, or a lot of swelling in your mouth, needs emergency care (NHS Dental abscess, 2026).

How do wisdom teeth cause jaw pain?

When wisdom teeth lack the space to come through fully, they can stay impacted, blocked by another tooth or partly covered by the gum. The NHS lists problems this can lead to, including pain, swelling, gum infection, tooth decay, cysts and abscesses (NHS Wisdom tooth removal, 2024).

A common source of sudden pain is pericoronitis, an infection or inflammation of the flap of gum that sits over a partly erupted tooth. The Scottish Dental Clinical Effectiveness Programme describes pain that is usually well localised to that tooth, with gum swelling that can spread into the face, especially around lower molars. Swallowing can hurt, opening is limited, there may be a bad taste, and some people feel feverish or unwell (SDCEP, 2026).

A recent review on trismus, the medical term for restricted mouth opening, names pericoronitis and dental abscesses as common causes, with the muscles tightening as a protective reflex (Falletti et al., 2026).

Is it your wisdom tooth or your jaw joint?

The SDCEP guideline says that pericoronitis and TMD can both cause pain and limited mouth opening, and advises considering TMD when a partly erupted wisdom tooth shows no signs of infection (SDCEP, 2026). The NHS describes TMD as pain around the jaw, ear or temple, with clicking or grinding noises and pain that gets worse with chewing or stress (NHS TMD, 2023).

It works the other way round too. An international review of toothache with no cause in the tooth itself put myofascial pain, meaning pain from the chewing muscles referred into the teeth, as one of eight groups of causes, and concluded that unnecessary dental treatment should be avoided (Yatani et al., 2014).

Often both are present. In an Australian clinic, 60 people referred for wisdom tooth removal were examined. 13.3% had signs and symptoms of jaw joint pain and dysfunction, and a further 23.3% had them alongside a wisdom tooth that was causing symptoms (DeAngelis et al., 2009). If your pain is mostly on one side, my article on why your jaw hurts on one side walks through the other common causes.

Why does your jaw hurt after wisdom tooth removal?

According to the NHS, pain and swelling can last up to 2 weeks and should start improving after 1 or 2 days. Bruising on the cheek, a sore and stiff jaw and discomfort when chewing or swallowing are all common (NHS Wisdom tooth removal, 2024).

The trismus review calls post-surgical trismus a common complication of dental procedures and links it to swelling after complicated wisdom tooth extractions and to local anaesthetic injections. The review notes that trismus in general often settles on its own within 2 weeks, although some people have symptoms that persist (Falletti et al., 2026).

Dry socket

Pain that gets much worse a few days after the extraction can mean dry socket. The blood clot in the socket fails to form or comes loose early, leaving bone exposed. Cleveland Clinic says it affects roughly 2% to 5% of extractions, is more common after wisdom tooth removal and usually appears within the first three days. Typical signs are pain spreading from the jaw towards the head and neck, a bad taste or bad breath. Smoking, straws and vigorous rinsing raise the risk, and with care it usually heals in about 7 to 10 days (Cleveland Clinic, 2025).

Can removal trigger TMD?

The research is mostly reassuring. A Danish study followed 72 people for six months after wisdom tooth surgery and compared them with 25 people without surgery. Jaw muscle and joint tenderness was more common for up to six months. Compared with the control group, the rise in TMD at six months was not statistically significant. Within the surgery group, though, painful TMD was more common at six months than before the operation (Juhl et al., 2009), so mention any existing jaw pain to your surgeon beforehand. A US study of 2,217 people with and 2,217 matched people without wisdom tooth removal found no statistically significant increase in TMD risk (Huang et al., 2008).

Do wisdom teeth need to come out?

Wisdom teeth do not automatically need to come out. A dentist may take X-rays to check how they are positioned, and a tooth that is not causing problems is usually left in place and monitored at routine check-ups (NHS Wisdom tooth removal, 2024). NICE guidance from 2000 states that preventive removal of impacted wisdom teeth with no disease should be discontinued in the NHS. It adds that a first episode of pericoronitis, unless particularly severe, should not count as a reason for surgery, while a second or later episode should be considered one (NICE TA1, 2000).

A Cochrane review found insufficient evidence to decide whether symptom-free, disease-free impacted wisdom teeth should be removed or kept. The authors recommend shared decision-making with your dentist and regular check-ups if you keep them (Ghaeminia et al., 2020).

Try it: tooth or muscle?

I use this check in physiotherapy when the source is unclear. It does not replace a dental examination.

1. Look behind your last molar. Use a mirror and note whether the gum there is red, swollen or tender, and whether you notice a bad taste.
2. Take your temperature. A fever points towards infection rather than TMD (SDCEP, 2026).
3. Measure your opening. Open slowly and see how many of your fingers, stacked flat, fit between your front teeth. Note the number and check again over the next few days to see whether it is improving.
4. Press your chewing muscles. With your jaw relaxed, press firmly but comfortably on the masseter, the thick muscle you feel bulge on your cheek above the angle of your jaw when you clench, and then on your temple. Notice whether that pressure reproduces your familiar ache.
5. Track it for a day. Write down whether the pain gets worse with chewing or when you feel stressed, which the NHS describes as typical of TMD (NHS TMD, 2023).

Red, swollen gum, a bad taste or a fever belongs with your dentist. In my practice, when pressing on the muscles sets off the familiar pain and the gum looks calm, the muscles are usually involved.

What helps with jaw pain around a wisdom tooth?

In the moment

For pericoronitis, the SDCEP guideline recommends good pain relief, rinsing with salt water or chlorhexidine mouthwash and seeing a dentist. Antibiotics are reserved for spreading or whole-body infection, or for people with weakened immunity, and the tooth may be removed in severe or repeated cases (SDCEP, 2026). After an extraction, the NHS advises paracetamol or ibuprofen, soft food and gentle salt water rinses, and no smoking or alcohol (NHS Wisdom tooth removal, 2024).

Long term

When the jaw muscles are the problem, the NHS suggests soft food, gentle massage and a wrapped cold or warm pack, whichever feels better. It also advises keeping your teeth apart except when eating (NHS TMD, 2023). The trismus review notes that stretching exercises may help after the acute phase when stiffness lasts longer than a week (Falletti et al., 2026). Start them only once your dentist says the area is healing well. Our TMJ exercises page has guided routines.

How JawBuddy helps

JawBuddy is a digital companion for guided jaw exercises and self-management, which suits the muscle side of the problem once your dentist has dealt with the tooth.

JawBuddy does not replace emergency care or an individual diagnosis from a qualified healthcare professional. Gum infection, swelling and problems after surgery always belong with your dentist first.

When should you see a dentist or doctor?

Emergency: call 999 or go to A&E (in the US, call 911) if:

• you find it hard to breathe, speak or swallow (NHS Dental abscess, 2026)
• you have a high-pitched sound when breathing or your voice becomes hoarse or muffled (SDCEP, 2026)
• you have a lot of swelling in your mouth, or swelling or signs of infection together with difficulty opening your mouth (NHS Dental abscess, 2026; SDCEP, 2026)
• your eye is swollen or painful, or you suddenly have problems with your eyesight (NHS Dental abscess, 2026)

Urgent: get an urgent dentist appointment or contact NHS 111 if:

• bleeding after an extraction will not stop (NHS Wisdom tooth removal, 2024)
• pain and swelling are severe or getting worse and painkillers do not help (NHS Wisdom tooth removal, 2024)
• you have pain with a bad taste in your mouth, a high temperature or feel unwell (NHS Wisdom tooth removal, 2024)
• your gum or face is swollen and you think you might have an abscess (NHS Dental abscess, 2026)
• pain after an extraction disrupts your sleep or does not ease with medication (Cleveland Clinic, 2025)

If you cannot eat or drink or your jaw locks, the NHS advises an urgent GP appointment (NHS TMD, 2023).

You do not have to guess where the pain comes from

Pain at the back of your jaw is unsettling. Do the tooth or muscle check, write down what you notice and take those notes to your next dental appointment. If the tooth turns out not to be the cause, our jaw pain page and the TMJ disorder guide are good next steps.
