That dull ache at the back of your jaw isn’t something you have to just put up with. Wisdom teeth have a habit of causing trouble right when you least expect it and if you’re reading this because your mouth is sore right now, you’re not alone.
Most adults feel some kind of wisdom tooth discomfort at some point, usually in their late teens or twenties, though it can crop up later too.
Here’s what’s actually going on and how to tell whether it’s something to keep an eye on or something to get looked at sooner rather than later.
Why Do Wisdom Teeth Hurt?
Wisdom tooth pain usually comes down to one thing: there often isn’t enough room at the back of the jaw for these teeth to come through properly.
Here’s why your wisdom teeth might be hurting:
- Wisdom Tooth Coming Through
As a wisdom tooth erupts, it’s fairly normal to notice:
- Pressure at the very back of the mouth
- Tender or slightly puffy gums around the area
- Mild discomfort, especially when chewing
- Food catching in the same spot again and again
- Impacted Wisdom Tooth
If there’s not enough space, the tooth can come through at an angle, only partly emerge, or stay trapped beneath the gum altogether. This is called impaction, and it’s one of the more common reasons people end up with ongoing pain, swelling, or pressure that doesn’t settle on its own.
- Food Trapped Around the Wisdom Tooth
As wisdom teeth sit so far back, they’re genuinely hard to clean properly. Food and plaque build up around a partially erupted tooth more easily than anywhere else in the mouth, which is often what tips a mildly uncomfortable tooth into an infected one.
- Inflammation Around a Wisdom Tooth
When gum tissue partly covers an erupting tooth, bacteria can get trapped underneath it. This leads to a condition called pericoronitis, a flare-up of inflamed, sore gum tissue that can come and go for weeks or months if it isn’t addressed.
What Are the Signs of a Problematic Wisdom Tooth?
Not every twinge means trouble, but a few signs are worth paying attention to:
- Pain or aching at the very back of the jaw
- Swollen, red or tender gums around the tooth
- Difficulty opening your mouth fully
- A bad taste or unpleasant odour that won’t go away
- Swelling that extends toward the jaw or cheek
- Discomfort that keeps coming back rather than settling
If you’re noticing a few of these together, it’s a good idea to have it checked rather than waiting to see if it passes.
Can a Wisdom Tooth Infection Go Away on Its Own?
Mild, short-lived irritation as a tooth erupts can settle by itself, particularly with good oral hygiene. An actual infection is a different matter: it may ease temporarily, especially with antibiotics if prescribed, but the underlying cause typically remains until the tooth is properly assessed and treated.
Left alone, infections around wisdom teeth can return and in some cases spread to nearby teeth, gum tissue, or the jaw. If you suspect infection, it’s best not to wait it out.
Do All Wisdom Teeth Need to Be Removed?
No. Plenty of people have wisdom teeth that come through straight, sit comfortably, and cause no issues at all and these can often be left alone and simply monitored at regular check-ups.
Removal is generally only considered when a tooth is impacted, causing pain, contributing to decay or infection, or affecting the health of surrounding teeth. This is very much a case-by-case decision, which is exactly why a proper dental assessment matters more than guessing based on symptoms alone.
When Is Wisdom Tooth Removal Considered?
Extraction tends to come up as an option when a wisdom tooth is:
- Repeatedly infected or inflamed
- Impacted at an angle that’s damaging or pressuring neighbouring teeth
- Contributing to decay that’s difficult to treat or clean around
- Causing cysts or other changes in the surrounding bone
- Making it hard to maintain oral hygiene in that part of the mouth
What Happens During a Wisdom Tooth Assessment?
Step 1: Dental Examination
Your dentist will check the position of the tooth, the condition of the gum tissue and look for signs of decay, infection, or crowding.
Step 2: Imaging if Clinically Indicated
An X-ray may be recommended to see how the tooth sits in relation to the jaw, nerves and neighbouring teeth, particularly if the tooth is impacted or only partly visible.
Step 3: Discussing Treatment Options
Not every case needs the same approach. You’ll be talked through whether monitoring, extraction or another form of management suits your situation.
Step 4: Personalised Treatment Planning
At Dental Studio Mooroolbark, our team includes Dr Henry Cheng, who has a particular interest in oral surgery and wisdom tooth extractions and Dr Rebecca Liu, who has completed further training in the surgical removal of impacted wisdom teeth. They will work through your options with you so you understand what’s involved before any decision is made.
Is Wisdom Tooth Removal Painful?
Modern extraction techniques and local anaesthetic are designed to keep you comfortable throughout the procedure itself and additional options such as sedation may be available for patients who feel anxious.
Everyone experiences recovery a little differently: some manage with over-the-counter pain relief, while others need a few more days to feel back to normal. Your dentist will talk you through what to expect for your specific case and how to manage any discomfort afterwards.
What Can I Eat After Wisdom Tooth Removal?
- Choose soft, cool foods during the first day or two, such as yoghurt, mashed potato, smoothies (without a straw), cooled soup and scrambled eggs.
- Avoid hot food and drinks while the area heals.
- Avoid crunchy or chewy foods that may irritate the extraction site.
- Avoid alcohol during the healing period.
- Follow your dentist’s aftercare instructions, as these will be tailored to your procedure.
How Long Does Wisdom Tooth Recovery Take?
Initial healing generally takes around a week to ten days, though this varies depending on how complex the extraction was and how many teeth were removed.
Full healing of the gum and bone underneath can take several weeks longer. Following your dentist’s aftercare advice closely gives you the best chance of a smooth recovery.
When Is Wisdom Tooth Pain a Dental Emergency?
Some symptoms shouldn’t wait for a routine appointment. Get in touch straight away if you’re experiencing:
- Severe, worsening pain that isn’t easing with pain relief
- Noticeable facial or jaw swelling
- Difficulty swallowing or opening your mouth
- Fever alongside tooth or gum pain
- A bad taste combined with visible discharge around the tooth

Conclusion
Wisdom tooth pain is common, but that doesn’t mean it should be ignored. Some discomfort settles on its own as the tooth finishes coming through, while other cases point to something that genuinely needs attention: infection, impaction or crowding that’s affecting the rest of your mouth.

Frequently Asked Questions
Why does my wisdom tooth hurt?
Wisdom tooth pain usually happens because there isn’t enough room at the back of the jaw for the tooth to come through properly. This can lead to pressure, an impacted wisdom tooth, or inflamed gum tissue around the area. A dental check-up can confirm exactly what’s causing your discomfort.
How do I know if my wisdom tooth is infected?
Signs of a wisdom tooth infection include swelling, a bad taste or odour, pain that worsens or keeps returning and difficulty opening your mouth fully. Some people also notice tenderness spreading toward the jaw. A dental examination is the only reliable way to confirm a tooth infection and start appropriate treatment.
Do all wisdom teeth need to be removed?
No, not every wisdom tooth requires wisdom teeth removal. Well-positioned teeth, fully erupted and causing no pain or crowding, can often simply be monitored at regular check-ups. Your dentist will only recommend extraction if there’s a clear clinical reason to do so.
What happens if I leave a painful wisdom tooth untreated?
An untreated impacted wisdom tooth or infection can worsen over time and may begin to affect neighbouring teeth, gum health, or the surrounding jawbone. Wisdom tooth pain that keeps returning is usually a sign the underlying issue needs attention rather than time. It’s best assessed early rather than left to progress.
Can an impacted wisdom tooth cause pain?
Yes, an impacted wisdom tooth is one of the most common causes of wisdom teeth pain, particularly when it’s pressing against a neighbouring tooth or trapped beneath the gum. This pressure can also lead to swelling, food trapping, and repeated gum inflammation. Treatment options will depend on the angle and depth of the impaction.
How do I know if I need wisdom tooth removal?
Whether you need tooth extraction depends on the position of the tooth, whether it’s causing pain or infection and how it’s affecting the teeth around it. This is best worked out through a dental examination and, if needed, imaging to see the tooth’s exact position. Every case is assessed individually rather than treated the same way.
Is wisdom tooth removal painful?
The procedure itself is carried out under local anaesthetic to keep you comfortable, with sedation options available for patients who feel anxious. Some mild discomfort during recovery is common and can usually be managed with pain relief as advised by your dentist. Your dental team will talk you through what to expect before you go ahead.
How long does wisdom tooth recovery take?
Initial recovery from wisdom teeth removal typically takes about a week to ten days, though this can vary depending on how complex the extraction was. Full healing of the gum and bone underneath can take a few weeks longer. Following your dentist’s aftercare instructions closely helps recovery go as smoothly as possible.
