Impacted Wisdom Teeth in Canberra: Assessed Properly Before Anything Is Removed
Impaction describes a position, not automatically a problem. The x-ray decides, not the word.
An impacted wisdom tooth is one that cannot come through into a normal position. At Dental Embassy in Braddon we assess impaction on imaging, explain what your particular teeth involve, and remove them in-house under sedation when removal is genuinely warranted.

Not every one needs removing
Being told your wisdom teeth are impacted sounds like a verdict. It is closer to a map reference. Impaction describes where a tooth is sitting and which way it is pointing, and on its own it does not decide whether anything needs to happen.
Plenty of impacted wisdom teeth sit quietly for a lifetime. Others cause repeated infections, damage the tooth in front, or build a cyst around the crown without producing a single symptom until the damage is done. Telling those groups apart is the entire job, and it is done on imaging rather than on the word itself.
The Types of Impaction
Wisdom teeth get stuck in a handful of recognisable ways, and the pattern matters because it predicts both the risk of trouble and the difficulty of removal.
A vertical impaction is pointing the right way but has not fully come through. A mesial impaction leans forward into the tooth in front, which is the most common pattern and the one most likely to cause decay on the back of the second molar. A distal impaction leans backwards. A horizontal impaction lies on its side, effectively pointing at the roots of its neighbour, and is usually the most involved to remove.
Depth matters as much as angle. A tooth fully covered by bone behaves very differently from one that has broken through the gum, which brings us to the single most useful distinction on this page.
Partly Erupted Teeth Cause the Most Trouble
A fully buried wisdom tooth is sealed away from the mouth. A partly erupted one is not, and that is the problem.
Where a flap of gum sits over part of the crown, it creates a pocket that no toothbrush can reach. Bacteria collect, the gum becomes inflamed, and you get pericoronitis: swelling and pain at the back of the jaw, often with a bad taste and difficulty opening. It typically settles with rinsing or antibiotics, then returns, because the pocket that caused it is still there.
That recurring pattern is one of the clearest indications for removal. It is also the reason a tooth that has been mildly annoying for two years can suddenly become the reason you cannot chew.
What the Imaging Tells Us
Assessment starts with an OPG, a single x-ray that shows both jaws and all four wisdom teeth in one image. That is usually enough to establish angle, depth, root shape and whether the tooth in front is being damaged.
For lower wisdom teeth there is a second question the OPG cannot always answer. The inferior alveolar nerve runs through the lower jaw and supplies sensation to your lip and chin. Where the roots appear to overlap it on a flat image, we take a CBCT scan, which shows the relationship in three dimensions and tells us whether the roots genuinely wrap the nerve or merely appear to.
That distinction changes the plan. It may change the surgical approach, and occasionally it is the reason we recommend leaving a tooth alone, because the risk of removing it outweighs the risk of keeping it. You will be told which group you are in.
When Monitoring Is the Better Answer
A fully buried, symptom-free wisdom tooth with no sign of damage to its neighbour and no cyst on the x-ray does not have to come out. Reviewing it at your regular check-ups is a defensible plan, and we are comfortable recommending it.
What tips it toward removal is evidence rather than anticipation: repeated pericoronitis, decay starting on the back of the second molar, bone loss behind that tooth, or a widening follicle around the crown that suggests cyst formation. Those are things we can show you on the image rather than assertions you have to take on trust.
There is one honest caveat. When removal does become necessary, it is generally more straightforward earlier, because roots are shorter and bone is less dense in younger patients. That is a reason to keep watching rather than a reason to operate now.
Removal, and Who Does It
Most dentists refer impacted wisdom teeth to an oral surgeon. Dr Simon Flanagan holds postgraduate qualifications in oral surgery, so at Dental Embassy the assessment and the removal happen in the same practice, with the same team, and without a referral or a separate waiting list.
Removing a buried tooth is a surgical procedure rather than a simple extraction. It usually means lifting the gum, removing a small amount of bone, and often sectioning the tooth so it can come out in pieces through a smaller opening. Sectioning sounds worse than it is: taking a tooth out in parts removes less bone than taking it out whole.
You can be awake, relaxed on happy gas, drowsy on oral sedation, or deeply relaxed under IV sedation administered by Dr Anna Huang, our dedicated sedationist. Most patients having more than one impacted tooth removed choose IV sedation and have all four done in a single visit.
Recovery
Expect more swelling and stiffness than after a simple extraction, because more tissue has been disturbed. Stitches are common, and jaw stiffness in the first few days is normal rather than a complication.
Days two and three are usually the peak, then it improves steadily. Most people take two to three days away from work, and longer if the job is physical. Avoid straws, smoking and vigorous rinsing for the first few days, because dislodging the clot is what causes dry socket. If pain increases three to five days afterwards rather than settling, call us: dry socket is easily treated once we see you, and it is not something to wait out.
Our recovery guide covers the day-by-day detail, and if you are in genuine trouble outside a planned appointment, see emergency dentistry.
Cost and Timing
Impacted teeth cost more to remove than erupted ones, because they take longer and involve a surgical approach. The variables are how many teeth, how deep and angled each one is, and which sedation you choose. You get an itemised quote after the consultation and imaging, before anything is booked.
On timing, we see a lot of students from the ANU campus at Acton, where the median age is 19, and this is exactly the age band when wisdom teeth declare themselves. If removal is on the cards, doing it during a semester break rather than in the middle of an assessment period is worth planning for. We are preferred providers for HCF, nib and Defence Health, claim through HICAPS, and offer interest-free payment plans. See our fees page.
Common Questions
Frequently Asked Questions
An impacted wisdom tooth is one that cannot come through into a normal position, because there is not enough room or because it is angled the wrong way. It may be fully buried in bone, partly buried, or partly through the gum. Impaction is a description of position, not a diagnosis in itself, and plenty of impacted wisdom teeth never cause a problem.
No. If an impacted tooth is fully buried, causing no symptoms, and shows no sign of damaging the tooth in front or developing a cyst, monitoring it at your regular check-ups is a legitimate approach. What changes the recommendation is evidence of a problem: recurrent infection, decay in the second molar, bone loss behind it, or cyst formation on the x-ray.
A partly erupted wisdom tooth creates a pocket between the gum flap and the crown that cannot be cleaned. Bacteria collect there and the gum becomes repeatedly inflamed, a condition called pericoronitis. It tends to flare, settle with rinsing or antibiotics, then flare again. Fully buried teeth are sealed away from the mouth and often stay quiet for decades.
From imaging. An OPG gives the overall picture, and where the roots appear close to the inferior alveolar nerve in the lower jaw we take a CBCT scan to see the relationship in three dimensions. Depth, angle, root shape and bone density all influence the approach, and we go through what your particular teeth involve before anything is booked.
The inferior alveolar nerve runs through the lower jaw near the roots of lower wisdom teeth and supplies feeling to the lip and chin. Where the roots sit close to it there is a risk of temporary altered sensation, and much less commonly of it being longer lasting. This is precisely why imaging matters before a lower extraction, and why we will tell you if your x-rays put you in a higher-risk group.
Usually not. Impacted wisdom teeth are routinely removed in the practice by Dr Simon Flanagan under local anaesthetic, with happy gas, oral sedation or IV sedation depending on what you want. IV sedation, administered by Dr Anna Huang, our dedicated sedationist, is the deepest option available here. If a case genuinely warrants a hospital general anaesthetic we will tell you and help arrange it.
Generally yes, though the difference is often smaller than people expect. Removing a buried tooth usually involves lifting the gum and taking away some bone, so there is more swelling and stiffness than after a simple extraction, and stitches are common. Most people find days two and three the worst, then a steady improvement. Plan two to three days away from work.
Only where the imaging suggests trouble is likely, rather than as a routine. What is true is that when removal is needed, it is usually more straightforward at a younger age: roots are shorter, bone is less dense, and healing is quicker. That is biology rather than a sales argument, and it does not mean every impacted tooth should come out.
