Most people who book in about their wisdom teeth aren’t sure whether what they’re feeling is actually a problem. A bit of soreness. A funny taste. A jaw that feels tight in the morning. Here’s what we look for in our practice — the symptoms that genuinely point to removal, the ones that usually don’t, and the handful that mean you shouldn’t wait until Monday.
The symptoms that actually matter
Pain that keeps coming back
A single sore day while a wisdom tooth pushes through is normal. Pain that flares up every few weeks, or a dull ache that never quite goes, is the body telling you something’s stuck. Most commonly the tooth is partially erupted and the gum around it is getting re-infected — we see this pattern a lot.
Swelling around the back gum
Puffy, red gum tissue over a wisdom tooth — often with a bad taste when you press on it — is usually pericoronitis. Healthdirect describes it as inflammation of the gums around a wisdom tooth, and it’s one of the top reasons we end up recommending removal. Food and bacteria slip under the gum flap, you can’t clean it properly, and it becomes a grumpy little pocket that flares repeatedly.
Mild cases settle with saltwater rinses and good cleaning. Recurrent cases don’t — and that’s the tipping point where the tooth usually needs to come out.
Bad breath or a bad taste you can’t shift
When you can’t clean around a half-erupted wisdom tooth, food rots in there. Patients often describe it as a metallic or “off” taste at the back of the mouth, or persistent bad breath despite brushing properly. On its own it’s a nuisance; combined with swelling or pain, it’s a pretty clear sign.
Jaw stiffness or trouble opening your mouth
If opening wide hurts, or your jaw feels stiff in the morning, there are a few possible causes — but an infected or impacted wisdom tooth is one of them. Struggling to open your mouth beyond a couple of fingers’ width (trismus) is a red flag for infection and warrants a same-day appointment.
Pressure or shifting on the next tooth
Sometimes the wisdom tooth pushes on the molar in front of it — Healthdirect notes impacted teeth can “come through at an angle and put pressure on the next tooth or the gums.” This can cause a persistent dull ache, or trap food between the two teeth where you can’t floss it out. On X-ray we often see early decay on the back of the second molar because of this, which is a legitimate reason to act.
Headaches and facial ache
A wisdom tooth biting awkwardly, or clenching around a sore one, can refer pain into the jaw muscles and temples. It’s not the first thing I’d blame a headache on, but if the pain patterns with chewing or sleeping on one side, it’s worth an examination.
Cysts or anything unusual on X-ray
Rarely, an impacted wisdom tooth develops a cyst around it — a fluid-filled sac that can damage bone or nearby teeth. You won’t feel this until it’s advanced, which is exactly why an OPG X-ray at your check-up matters. It’s uncommon, but when we see it we act.
If any of that is ringing bells, it’s worth booking a consult with me at Biltoft so we can take an X-ray and talk through whether removal actually makes sense for your situation.
Symptoms that usually don’t mean removal
Not every ache is a problem. In our practice these are the ones we reassure people about:
- A few days of tenderness as the tooth erupts. If it settles within a week or two and you can eat normally, that’s just eruption.
- Mild soreness after a tough chew. Gums bruise. Give it 48 hours.
- A tooth that “feels weird” but looks straight on X-ray. If it’s upright, cleanable, and asymptomatic, leaving it alone is a valid plan. The Australian Dental Association’s patient resources and Healthdirect both reinforce that not every wisdom tooth needs to come out.
We genuinely don’t remove healthy wisdom teeth just because they exist. If yours are doing their job, we’ll check them at your regular visits and leave them alone. You can read more about this approach in our full wisdom teeth guide.
When it’s urgent — don’t wait
Some symptoms mean same-day care, not “I’ll ring on Monday”:
- Fever alongside tooth or gum pain
- Swelling spreading across your cheek, under your jaw, or down your neck
- Difficulty swallowing or feeling like your airway is tightening
- Difficulty opening your mouth beyond a finger or two
- A hot, hard lump under the jaw
These can indicate a spreading dental infection, which occasionally becomes serious. Ring us on (02) 6672 1980 during hours, or go to the nearest emergency department if it’s out of hours or the swelling is progressing quickly. I’d rather see you at 8am and send you home reassured than have you tough it out.
What happens when you come in
A wisdom teeth consult at Biltoft is pretty straightforward. We’ll talk through your symptoms, look at the teeth, and take an OPG (the panoramic X-ray that shows all four wisdom teeth and how they sit in the jaw). From there we’ll sort you into one of three plans:
- Leave it alone and monitor. Often the right answer.
- Treat conservatively. Sometimes a clean, a better brushing routine, and a course of antibiotics for an active infection is all that’s needed — buying the tooth time to finish erupting properly.
- Plan removal. If the pattern of symptoms and the X-ray both point that way.
If removal is on the cards, we do straightforward extractions in-chair under local anaesthetic. Our fee is $500 to $650 per tooth. We don’t offer IV sedation or general anaesthetic at Biltoft — for patients who need that (very anxious, all four impacted, complex anatomy), we refer to a specialist oral surgeon and explain what to expect. It’s honest rather than ideal, and it means you get the right setting for your case.

The short version
Book a consult if you’ve got:
- Pain that keeps coming back
- Swelling, pus, or a bad taste around a back tooth
- Jaw stiffness that’s not settling
- Persistent bad breath you can’t explain
- Pressure or food-trap issues with the tooth in front
Skip the worry if it’s a few days of eruption tenderness with no swelling or fever.
Go straight to urgent care if you’ve got spreading swelling, fever, or difficulty swallowing or opening your mouth.
If you’re somewhere in the middle and just not sure, that’s exactly what a consult is for. Ring us on (02) 6672 1980 or book online and we’ll take a proper look. Individual cases vary — the plan we make together will be the one that suits your mouth, not a one-size-fits-all.

Frequently asked questions
Is mild soreness at the back of my mouth always a sign I need surgery? +
No. Wisdom teeth pushing through the gum can cause a few days of tenderness, the way a toddler's molar does. If it settles within a week or two, eating is normal, and there's no swelling or bad taste, it's usually just eruption. It's the symptoms that stick around, come back repeatedly, or get worse that matter.
What's pericoronitis? +
It's inflammation of the gum flap over a partially erupted wisdom tooth. Food and bacteria get trapped under the flap and the gum becomes red, swollen, and sore. Healthdirect describes it as 'when the gums around your wisdom teeth become inflamed.' It's one of the most common reasons we end up recommending removal.
When is wisdom tooth pain a dental emergency? +
Call us straight away if you have spreading facial swelling, fever, difficulty swallowing, trouble opening your mouth beyond a finger's width, or swelling that's moving down your neck. Those signs can point to a spreading infection and need same-day care — if you can't reach a dentist, head to an emergency department.
Can wisdom teeth cause headaches or jaw pain even if they look fine? +
They can. A tooth biting awkwardly against the one opposite, or clenching around a sore gum flap, can refer pain into the jaw muscles and temples. We'd want to examine you and take an OPG X-ray before blaming the wisdom teeth, though — plenty of headaches have nothing to do with them.
Do I need removal if my wisdom teeth are coming in straight and not hurting? +
Usually not. If they're upright, fully erupted, you can clean them, and they're not causing symptoms, leaving them alone is a legitimate plan. We'd keep an eye on them at your regular check-ups. We don't remove healthy wisdom teeth just because they're there.
How much does wisdom tooth removal cost at Biltoft? +
Our fee is $500 to $650 per tooth under local anaesthetic. We don't offer IV sedation or general anaesthetic in-house — if you need that, we'll refer you to a specialist oral surgeon and explain why. Individual cases vary, so the exact number comes out of your consult.
