Wisdom teeth cause more grief than almost any other tooth in the mouth. They are the last to come through, often there is no room for them, and the problems they cause range from a mild ache to a full-on emergency with facial swelling. At Dentist Pymble, we assess and remove wisdom teeth for patients across the Ku-ring-gai region, and the questions we get are almost always the same: does it have to come out, what does the procedure involve, and what is recovery really like. This page answers all of those in plain language.
What causes wisdom tooth pain?
The most common cause is pericoronitis — inflammation and infection of the gum flap sitting over a wisdom tooth that has only partially come through. Food and bacteria get trapped under the flap, the gum swells, and you end up with a throbbing pain at the back of the jaw, often with a bad taste, difficulty opening the mouth, and swollen lymph nodes under the jaw.
The other common causes are decay (a partially erupted wisdom tooth is hard to clean and decays quickly), pressure from a wisdom tooth pushing against the tooth in front, and — for fully impacted teeth — a cyst forming around the crown. Any of these can produce pain that ranges from a dull background ache to a severe throbbing that wakes you at night.
Do all wisdom teeth need to be removed?
No, and this is worth saying clearly. Plenty of people have wisdom teeth that come through straight, clean well, and never cause trouble. The decision to remove should be based on the angle, depth, available space, and the presence of active disease — not on age alone, and not on the assumption that everyone needs them out.
The wisdom teeth that usually do need to come out are those that are impacted against the tooth in front, horizontally angled, partially erupted with repeated infections, decayed beyond repair, or associated with a cyst. The wisdom teeth we leave alone are fully erupted, accessible to clean, and not causing any symptoms. The right answer is the one your dentist reaches after looking at an x-ray (usually an OPG) and examining the mouth.
What is an impacted wisdom tooth?
An impacted wisdom tooth is one that does not have enough room to come through into the mouth in a useful position. It might be angled forward into the tooth in front (mesioangular), angled backward (distoangular), lying on its side (horizontal), or pointing straight up but stuck against bone or gum (vertical). The deeper the impaction, the more complex the surgery tends to be. We use an OPG or a small 3D scan to plan the approach and to flag any proximity to the nerve that runs through the lower jaw.
When should I see a dentist about wisdom tooth pain?
Sooner rather than later. If the pain has lasted more than a day or two, if the gum at the back is swollen or bleeding, if you can see a flap of gum over a partially erupted tooth, if you are finding it hard to open your mouth, or if you have a fever or swelling under the jaw, it is time to book in. We keep same-day emergency dentist slots for exactly this kind of presentation at our Pymble practice.
The earlier we see you, the more options we have. A first episode of pericoronitis often settles with a clean-out and a saltwater rinse. Repeated episodes are usually the trigger to plan an extraction rather than waiting for a full-blown infection or facial swelling.
How is a wisdom tooth extracted in Pymble?
A wisdom tooth that has fully come through can often be removed under local anaesthetic with the same instruments used for any other extraction. The tooth is rocked gently to expand the socket and then lifted out. Stitches are usually not needed, and the appointment is short.
A wisdom tooth that is impacted or partially erupted usually needs a surgical extraction. The gum is lifted, a small amount of bone is removed from around the tooth, and the tooth is either lifted out whole or sectioned into smaller pieces that come out through a smaller opening. Stitches are usually placed, and the appointment takes 30-60 minutes. We offer local anaesthetic with or without oral or IV sedation for nervous patients, and we can refer complex cases to a specialist oral surgeon under general anaesthetic in a day-stay hospital setting when needed.
What does wisdom tooth recovery look like?
The first 24 hours are the most uncomfortable. Expect some oozing, facial swelling that peaks at day 2-3, and a dull ache that responds to over-the-counter pain relief (ibuprofen plus paracetamol is the usual combination, assuming no medical reason to avoid them). Keep your head elevated, use cold packs on the cheek for 15 minutes on, 15 minutes off, and stick to a soft food diet — yoghurt, smoothies (no straws), scrambled eggs, mashed potato.
From day 2, gentle saltwater rinses after meals help keep the socket clean. Avoid smoking, vaping, and alcohol for at least 72 hours, as all of them increase the risk of dry socket. Most people are back at work or study within 2-4 days for a simple extraction, and 5-7 days for a surgical one. The socket itself takes a few weeks to fully heal, with the gum closing over gradually.
How much does wisdom tooth removal cost in Pymble?
The cost varies significantly based on the complexity of the case. A simple extraction under local anaesthetic is at the lower end. A surgical extraction with sedation is in the middle. A hospital-based general anaesthetic case with a specialist oral surgeon is at the top. We will always provide a written quote after the assessment and OPG, run a health-fund check on the day, and talk through item numbers so you know exactly what is and is not covered.
If you live in Pymble, Gordon, Turramurra, Wahroonga or anywhere else in the Ku-ring-gai area and you have wisdom tooth pain, call our practice. We see neighbouring Gordon patients and other nearby residents, and we will always be honest with you about whether removal is the right call or whether it is worth waiting.
Frequently asked questions
At what age do wisdom teeth come through? Most people see their wisdom teeth emerge between 17 and 25, but the range is wide. Some people never develop them at all, and some develop them in their 30s or later.
Is wisdom tooth removal painful? No — the procedure itself is done under local anaesthetic, with sedation available if you are nervous. The first few days of recovery involve some swelling and discomfort, but this is manageable with over-the-counter pain relief and responds well to ice and rest.
Can I drive home after wisdom tooth removal under sedation? No. If you have had oral or IV sedation, you will need a responsible adult to drive you home and stay with you for the rest of the day. For a straight local anaesthetic without sedation, most patients are fine to drive.
How long does wisdom tooth recovery take? Most people feel back to normal within a week for a simple extraction and 1-2 weeks for a surgical one. The gum takes longer to fully close over the socket — usually 2-4 weeks — but that does not usually cause symptoms.
What happens if I leave an impacted wisdom tooth alone? It depends. If the tooth is symptom-free, fully covered by bone, and being monitored with regular x-rays, leaving it alone is reasonable. If it is decayed, infected, pushing on the tooth in front, or associated with a cyst, leaving it almost always leads to bigger problems later. The right answer depends on the individual case.
